Sooner or later, almost every French Bulldog needs anesthesia, whether for a spay or neuter, a dental cleaning, airway surgery or a scan, and French Bulldog anesthesia comes with a few extra steps. If you’ve read that flat-faced dogs are risky under anesthesia, it’s normal to feel nervous. Here’s the honest picture: anesthesia is very safe for most healthy dogs. Frenchies do need extra care, and most of that extra care is something you can ask for.

This guide covers how safe anesthesia really is, why flat-faced dogs need a different plan, the role of reflux, what a Frenchie-smart clinic does, the questions to ask, how to prepare and the red flags to watch for afterward. If your Frenchie snores or tires quickly, read our French Bulldog BOAS guide alongside this one. The airway is at the center of the anesthesia story.

🐾 Bodhi Says

If I ever need the sleepy medicine at the vet, my mom has a list of questions longer than my favorite chew. She says flat-faced guys like me need someone watching extra closely while we wake up. For the record, I am already an expert at waking up. Especially when the fridge opens.

How Safe Is Anesthesia for Dogs?

Anesthesia is very safe for most healthy dogs. In a large UK study, about 1 in 1,850 healthy dogs died from anesthesia-related causes, compared with about 1 in 75 sick dogs. A US study of 1.8 million procedures found about 1 in 2,000 dogs died. Most of the risk comes from illness, emergencies, bigger procedures and older age.

The best data come from two big studies. In the UK, researchers followed anesthetics and sedations in 117 vet practices from 2002 to 2004, counting deaths within 48 hours. Overall, 0.17% of dogs died from anesthesia-related causes, about 1 in 600. For healthy dogs the figure was 0.05%, about 1 in 1,850. For sick dogs it was 1.33%, about 1 in 75 (Brodbelt et al., 2008a). In the US, a study of 1,817,193 anesthetic events in 822 Banfield hospitals found a death rate of 0.05% in dogs, about 1 in 2,000 (Matthews et al., 2017).

What drives the risk? In the UK risk-factor analysis, each step up in the health score raised the odds of death about 6.6 times. Emergency surgery, major procedures, age 12 or older and weighing under 5 kg (about 11 lb) also raised the odds (Brodbelt et al., 2008b). Breed mattered only before adjusting for body weight, though the authors still advised caution with flat-faced breeds.

The part owners don’t expect. Many deaths happen after the procedure is over. In the UK study, 47% of dog deaths happened in the postoperative period (Brodbelt et al., 2008a), and AAHA notes that most of these happen within the first 3 hours (AAHA, 2020). In the US study, 60% of the dog deaths happened after the dog had gone home (Matthews et al., 2017). That’s why recovery gets so much attention in this guide.

The same US study found that dogs with no recorded exam before anesthesia had far higher odds of dying. The estimate was imprecise because it rested on small numbers, but the message is simple: a hands-on exam matters (Matthews et al., 2017). Being underweight and needing a non-elective procedure also raised the odds.

Why Flat-Faced Dogs Need Extra Care

Flat-faced (brachycephalic) dogs, including French Bulldogs, have narrow airways and are prone to reflux. In an Ohio State study, they had about four times the odds of a complication after anesthesia: about 1 in 7 flat-faced dogs vs 1 in 28 other dogs. Only flat-faced dogs developed aspiration pneumonia. Studies show more complications, not proof of more deaths.

Specialist anesthetists describe two sources of extra risk in flat-faced dogs: the airway and the gut. BOAS, the breathing disorder caused by a short face and crowded throat tissue, makes breathing harder once sedation relaxes the throat. Reflux of stomach contents adds a second risk (Downing & Gibson, 2018). Our BOAS guide covers the airway side.

The clearest numbers come from Ohio State University. Researchers matched 223 flat-faced dogs with 223 other dogs having the same procedures, routine surgery or imaging, and compared complications (Gruenheid et al., 2018). During anesthesia, the raw complication rates were almost the same, about half of each group. After adjusting for other factors, flat-faced dogs had about 1.57 times the odds of a complication during anesthesia. The real gap opened after anesthesia: 13.9% of flat-faced dogs had a complication in recovery, compared with 3.6% of other dogs, with adjusted odds about 4.33 times higher. Nine flat-faced dogs developed aspiration pneumonia, which happens when stomach contents are breathed into the lungs. None of the other dogs did. Two dogs died, both flat-faced.

The same study found that every extra 30 minutes of anesthesia raised the odds of complications by about 18%, and invasive surgery raised the odds of trouble in recovery (Gruenheid et al., 2018).

Are Frenchies more likely to die? We don’t know for sure. A 2018 Australian specialist review noted that, at the time, no published studies supported higher anesthetic death rates in flat-faced dogs (Fawcett et al., 2019). The UK study found breed wasn’t significant after adjusting for weight (Brodbelt et al., 2008b), and the US study didn’t report flat faces at all. What the research does show clearly is more complications, especially in recovery. We found no anesthesia study of Frenchies alone; these studies mix flat-faced breeds, including Frenchies.

Reflux, Regurgitation and Fasting

Many French Bulldogs have reflux or regurgitation, which raises the risk of stomach contents reaching the lungs during recovery. Tell your vet if your Frenchie ever regurgitates. Ask about an anti-reflux plan and a fasting plan. AAHA’s guidelines suggest that regurgitation-prone dogs may do better with a small meal 4–6 hours before anesthesia than a long fast.

Gut problems are very common in Frenchies with BOAS. In a UK study of dogs having airway surgery, 93% of the 43 French Bulldogs had gut signs such as vomiting, regurgitation or drooling, more than English Bulldogs or Pugs (Kaye et al., 2018). In an Italian series of 176 Frenchies with BOAS, 46.6% regurgitated and 26.7% had a hiatal hernia, where part of the stomach slides up through the diaphragm (Bottero et al., 2025). These are Frenchies with BOAS referred for surgery or endoscopy, so the numbers are likely higher than in Frenchies overall. Still, regurgitation is common enough to ask about. Our French Bulldog gut health guide covers the everyday side.

Why it matters under anesthesia. Reflux can inflame the esophagus, cause aspiration pneumonia and, rarely, scar the esophagus (AAHA, 2020). After airway surgery, a history of regurgitation predicted regurgitation afterward (Costa et al., 2020). So tell your vet if your Frenchie ever brings food back up, even occasionally.

Reflux can follow anesthesia, too. Dr. Judy Morgan lists general anesthesia among the causes of acid reflux, and Hemopet, Dr. Jean Dodds’s organization, notes that reflux can follow anesthesia, with signs such as regurgitation and constant lip licking. Dr. Katie Woodley adds that “silent” reflux often shows up as gulping and lip licking at night. If you see these signs in the days after a procedure, tell your vet and ask about gut support. Integrative vets lean on smaller meals, diet changes and soothing herbs such as slippery elm or marshmallow, given apart from meals and medicines, and Hemopet treats acid reducers as short-term aids rather than a long-term fix. Retching with a swollen belly is different: call your vet or an emergency clinic now.

Anti-reflux plans. No single pill reliably prevents regurgitation. AAHA’s anesthesia guidelines say the anti-nausea drug maropitant helps prevent vomiting but has less effect on reflux, and that metoclopramide, ranitidine and omeprazole combined with maropitant appear to have minimal impact on regurgitation. For at-risk dogs, AAHA says an acid reducer such as omeprazole, given the evening before and the morning of anesthesia, can be considered, to make any reflux less acidic (AAHA, 2020). A 2018 Australian specialist review advises starting omeprazole the day before elective surgery in flat-faced dogs (Fawcett et al., 2019). Doses and timing are your vet’s call.

Bundled protocols look more promising than any one drug. At one hospital, flat-faced dogs having airway surgery got a standard plan: two stomach medications before surgery (metoclopramide and famotidine), careful limits on opioid pain drugs and recovery in intensive care. Regurgitation after surgery fell from 35% to 9% (Costa et al., 2020). Pneumonia and breathing distress didn’t change, and several things changed at once, so no single drug gets the credit.

How long should a Frenchie fast? The old rule was “nothing after midnight.” AAHA’s 2020 guidelines say recommended fasts for healthy adults have become shorter, that water can usually stay available and that very young puppies (under 8 weeks or under 2 kg) shouldn’t fast for more than 1–2 hours. For dogs with a history of regurgitation, or at risk of it, AAHA suggests considering a small meal of 10–25% of the normal amount 4–6 hours before anesthesia, along with anti-nausea, antacid and gut-motility medications (AAHA, 2020). The Australian review also recommends short fasts for flat-faced dogs (Fawcett et al., 2019). Follow your clinic’s instructions, and ask whether a small early meal makes sense.

Before Anesthesia: Exam, Bloodwork and a Plan

Every Frenchie should have a hands-on exam before anesthesia, with a look at the airway, heart and lungs. Bloodwork helps your vet spot hidden problems and is especially worth it for older or sick dogs. Share your dog’s full history, including snoring, regurgitation, past anesthetics and every medication and supplement. Ask about calming medication if your dog gets anxious.

AAHA lists a documented physical exam before anesthesia as a key risk-reducing step, along with correcting problems such as low blood sugar, electrolyte imbalances and anxiety before the procedure (AAHA, 2020). The American College of Veterinary Anesthesia and Analgesia (ACVAA) explains in its owner guide that blood tests may be ordered to check how well the organs that handle anesthetic drugs are working (ACVAA owner guide). We found no study showing that routine bloodwork lowers deaths in young, healthy dogs, so we won’t claim it does. But it’s a small price for information, and many vets require it.

For a Frenchie, the exam should include the airway. Ask your vet to check the airway and to note any snoring, noisy breathing, gagging or regurgitation in the record. If your Frenchie has been graded for BOAS, bring the result. If your dog has had airway surgery before, say so; it may lower the risk of later anesthetics, as you’ll see below.

Medications on the day. AAHA’s guidelines say most medications continue as usual. Behavior medications, pain medications and steroids shouldn’t be stopped suddenly. Some heart medications called ACE inhibitors are usually held on the day of anesthesia, blood thinners may need to stop about two weeks ahead and a fasting diabetic dog shouldn’t get a full insulin dose (AAHA, 2020). Your vet will tell you exactly what to give and what to hold.

A calm, cool dog. AAHA says anti-anxiety medication should be given to fearful or aggressive patients and strongly considered for any dog with fear, anxiety or stress; gabapentin and trazodone are commonly used. Calming premedication also lowers the amount of anesthetic needed (AAHA, 2020). Heat matters too. We found no anesthesia study on it, but common sense says skip exercise, keep the car cool and avoid a hot waiting room on surgery day. See our French Bulldog heat safety guide.

No vaccines the same day. Vaccines are labeled for healthy animals. Dr. Morgan says they should never be given to a pet undergoing anesthesia (Morgan, 2019a), and recommends no vaccines for at least two weeks before or two months after spay or neuter surgery (Morgan, 2023). She also advises no Bordetella (kennel cough) vaccine within 4 weeks of anesthesia and considers flat-faced dogs poor candidates for the nose-drop version. We found no mainstream guideline that sets a specific gap, but scheduling shots apart from surgery is easy to ask for. Our French Bulldog vaccines and titers guide has the details.

During Anesthesia: Oxygen, Monitoring and Warmth

A Frenchie-smart clinic gives oxygen before putting your dog to sleep, places a breathing tube quickly and has one trained person watching your dog the whole time. The 2025 US veterinary anesthesia standards call for pulse oximetry, capnography, blood pressure, ECG and regular temperature checks with active warming. Ask whether your clinic does all of these.

Pre-oxygenation. Breathing oxygen for a few minutes before anesthesia builds a reserve in case placing the breathing tube takes longer. In a study of 20 healthy dogs, 3 minutes of oxygen by face mask gave about 298 seconds before oxygen levels dropped to 90%, compared with about 70 seconds on room air, roughly four times longer (McNally et al., 2009). AAHA says pre-oxygenation should be considered part of the standard sequence (AAHA, 2020), and the Australian specialist review calls it essential in flat-faced dogs because placing the tube can be difficult (Fawcett et al., 2019). The study was in healthy dogs; we found no pre-oxygenation study in flat-faced dogs.

Getting the tube in quickly. The Australian review recommends calming sedation first and fast-acting drugs to put the dog to sleep (Fawcett et al., 2019). In the Ohio State study, dogs induced with ketamine plus a benzodiazepine had higher odds of complications than dogs given propofol (Gruenheid et al., 2018). Drug choice is your vet’s call, but it’s fair to ask whether the plan is adjusted for a flat-faced dog. AAHA’s dental guidelines put it plainly: flat-faced breeds and their airways warrant particularly close attention, and every anesthetized patient should have a breathing tube (AAHA, 2019).

Monitoring. According to AAHA, a lack of monitoring raises the odds of anesthetic death by a factor of 5 to 35.5 (AAHA, 2020). In 2025, the ACVAA published minimum monitoring standards for every anesthetized dog and cat (Bailey et al., 2025). Here’s what they ask for, in plain English.

Warmth. Small dogs lose heat quickly under anesthesia, and the Ohio State team recorded low body temperature as one of the complications they tracked (Gruenheid et al., 2018). AAHA calls temperature monitoring critical, with warming started early and continued through recovery (AAHA, 2020). Ask how your clinic keeps your Frenchie warm during and after the procedure.

Waking Up: The Breathing Tube and Recovery

Recovery is the riskiest stretch for a flat-faced dog. Specialists advise keeping the breathing tube in until a Frenchie is fully awake and can’t tolerate it any longer, then not leaving the dog unattended for the first 12 hours after it comes out. The first 3 hours after anesthesia carry the highest risk, so ask who will watch your dog and for how long.

The breathing tube holds a Frenchie’s narrow airway open and protects the lungs from reflux. Take it out too early, while the throat muscles are still relaxed, and the airway can collapse or clog. The Australian specialist review says removing the tube in flat-faced dogs is normally delayed until the dog is fully awake and can no longer tolerate it, and that dogs must not be left unattended for the first 12 hours after it comes out (Fawcett et al., 2019). This is expert advice, not trial data. AAHA adds that the tube should come out only once breathing and oxygen levels are normal, with the nose angled down to lower the risk of aspiration (AAHA, 2020).

Dr. Judy Morgan describes a similar approach: the tube comes out once the pet is sitting up and able to swallow, and vital signs are watched until the pet is awake and walking (Morgan, 2022). The 2025 ACVAA standards call for continuous observation until the patient is stable and say pets should go home only when they’re warm, alert, walking (unless the procedure prevents it) and free of nausea and pain (Bailey et al., 2025).

After airway surgery, plan on an overnight stay. In a series of 248 dogs having airway surgery, about 23% had breathing complications afterward, mostly breathing difficulty needing oxygen, a new breathing tube or a temporary tracheostomy (a tube placed through the neck). About 2.4% died. Older dogs, dogs with existing airway disease and emergency cases were at higher risk. The authors recommend monitoring for at least 24 hours after surgery (Lindsay et al., 2020). Ask where your Frenchie will spend the first night.

10 Questions to Ask Your Clinic Before Anesthesia

Before any anesthetic, ask how often the clinic handles flat-faced dogs, who will watch your Frenchie, which monitors they use, how they keep dogs warm, whether they pre-oxygenate, what the anti-reflux and fasting plan is and when the breathing tube comes out. A good clinic will welcome the questions.

You don’t need to be an expert to ask good questions. Every question below traces back to a guideline, a study or specialist advice cited in this guide.

If a clinic brushes off these questions, that tells you something. For older, sick or severe-BOAS Frenchies, AAHA notes your vet can bring in a board-certified anesthesiologist or dentist (AAHA, 2019). Our veterinarian directory can help you find vets near you.

The Day Before, the Day Of and the First 24 Hours

Prepare ahead: book a pre-op exam, share your dog’s full history and get written fasting and medication instructions. On the day, keep your Frenchie calm and cool. At pick-up, ask what’s normal and who to call after hours. For the first night, keep your dog close, cool and quiet, and watch breathing, gum color and any vomiting or regurgitation.

These steps follow AAHA’s preparation and home-recovery advice (AAHA, 2020) and the ACVAA discharge standards (Bailey et al., 2025). “Don’t leave your dog alone tonight” is our own caution, based on the recovery risk in flat-faced dogs.

Red Flags After Surgery

Call your vet or emergency clinic now if your Frenchie struggles to breathe, has pale, blue or gray gums, collapses or can’t be woken easily. Call right away for vomiting or regurgitation, a moist or worsening cough or black, tarry stools while on pain medication, and call the same day if your dog refuses food or has low energy beyond 24 hours.

Most of the extra risk for flat-faced dogs comes after anesthesia, and most US deaths happened after discharge (Gruenheid et al., 2018; Matthews et al., 2017). Check your Frenchie’s gums before surgery day so you know what normal looks like.

Airway Surgery, Spay or Neuter and Combining Procedures

Many vets combine a Frenchie’s spay or neuter with airway surgery or another procedure, so the dog has one anesthetic instead of two. Airway surgery also appears to make later anesthetics safer. But every extra 15 minutes under anesthesia adds risk, so the right plan depends on your dog. Talk it through with your surgeon.

Airway surgery may make later anesthetics safer. Ohio State researchers compared 45 flat-faced dogs with themselves, across anesthetics before and after corrective airway surgery. After airway surgery, the odds of complications in recovery were 79% lower (Doyle et al., 2020). It’s a small, single-center study, but encouraging. It found that each extra 15 minutes of anesthesia raised the odds of a complication in recovery by about 12%.

What happens when procedures are combined? In a study of 55 dogs having airway surgery, 38% had other procedures at the same time, including 7 spays or neuters. The researchers found no separate effect of the extra procedures on major complications. But longer surgery was linked to needing a temporary tracheostomy, and the authors suggest limiting extra procedures (Ree et al., 2016). Insurance data from Australia show that vets do combine: 11% of flat-faced dogs had another surgery at the time of desexing, compared with 7% of other dogs. The most common were hernia repairs, airway surgery and cherry eye repair (Fawcett et al., 2019). No study has compared combined and separate surgeries in Frenchies.

Timing of airway surgery. Older age predicted complications after airway surgery in the 248-dog series, and those authors suggest considering surgery at a younger age as a planned procedure (Lindsay et al., 2020). But a Cambridge study found younger age predicted a poorer breathing outcome after surgery (Liu et al., 2017). So early assessment matters, and the timing of surgery is a decision for you and a surgeon experienced with BOAS. For a sense of cost, one UK referral hospital lists its BOAS surgery package at £3,775, including the anesthetic, intensive care and medication (prices correct at April 1, 2025; Langford Vets, 2025). It’s a good reason to have pet insurance in place early.

When to spay or neuter. No large study has set an ideal neuter age for French Bulldogs. An early Italian study linked spaying Frenchie females before 12 months with much higher odds of disc herniation, but it wasn’t adjusted for other factors and the authors call it preliminary (Tabbì et al., 2025). Dr. Karen Becker and Dr. Peter Dobias favor hormone-sparing options such as an ovary-sparing spay or a vasectomy, and Dr. Morgan rejects routine spay or neuter at 6 months (Becker, 2024; Dobias, 2026; Morgan, 2019b). Our French Bulldog puppy guide and IVDD guide cover the timing question in more depth.

Dental Cleanings Need Anesthesia

A real dental cleaning needs general anesthesia with a breathing tube. Anesthesia-free cleanings only scrape and polish what you can see, can’t clean below the gumline or include X-rays and leave the airway unprotected. AAHA, the American Veterinary Dental College and US veterinary anesthesiologists all advise against them. Daily brushing can mean fewer cleanings over your Frenchie’s life.

We understand the appeal of skipping anesthesia for a flat-faced dog; AAHA notes that fear of anesthesia is the most common reason owners skip proper dental care. But AAHA calls anesthesia-free dentistry not appropriate because of stress, injury, aspiration risk and the lack of diagnostic ability. Cleaning above the gumline alone is purely cosmetic, and AAHA adds that anesthesia risk is very low in healthy patients with trained staff (AAHA, 2019). The American Veterinary Dental College says anesthesia-free scraping isn’t an effective way to prevent dental disease, and that cleaning below the gumline of every tooth is impossible in an awake dog (AVDC, 2024). The ACVAA board backs AAHA’s standard that every dental cleaning be done under general anesthesia with a breathing tube (ACVAA, 2013).

Most dental disease can’t be seen in an awake dog. In a review of studies, vets checking awake dogs recorded gum disease in 9.3–18.2% of them, while detailed exams under anesthesia found it in 44–100% (Wallis & Holcombe, 2020). The review was funded by Mars Petcare. Dr. Judy Morgan agrees that non-anesthetic cleaning is mostly cosmetic, calls the anesthetic cleaning the gold standard and stresses dental X-rays to see the roots (Morgan, 2022).

The best way to need fewer anesthetics is daily home care from puppyhood. Our French Bulldog dental care guide covers brushing, chews and what a professional cleaning involves. Dr. Morgan notes that high-risk pets may be referred to a veterinary dental specialist (Morgan, 2022).

Integrative Support Before and After Anesthesia

Give your vet a full written list of every supplement, herb, oil and CBD product your Frenchie takes, and ask which to continue and which to pause before surgery, especially anything that can affect clotting. Don’t stop or start anything on your own. After surgery, ask about gut support if antibiotics are prescribed, and keep your dog calm, cool and well nourished.

Many Frenchie families use fish oil, mushrooms, herbs or CBD. Your vet needs to know about all of it before anesthesia. Dr. Katie Woodley says a vet’s review of supplements is especially important for pets with a bleeding disorder or an upcoming procedure, and that the vet should look at supplements that may affect clotting (Woodley, 2026). Notice what she doesn’t say: she doesn’t tell owners to stop fish oil before surgery. We found no guideline or study that gives a list of supplements to stop or a set number of days to pause them, so we won’t publish one. Your vet will decide based on your dog and the procedure.

After surgery. Dr. Morgan suggests probiotics if your pet is prescribed antibiotics, limiting activity while your dog heals and watching for side effects of anti-inflammatory pain drugs, such as tarry stools or vomiting (Morgan, 2023). Our probiotics guide for French Bulldogs explains what the research shows. Dr. Morgan also recommends a set of liver-support supplements around anesthesia; she doesn’t cite studies for it, and we found none, so we leave that decision to you and your vet.

Acupuncture, laser and rehab. Integrative vets such as Dr. Gary Richter use acupuncture, rehab and natural remedies to help pets recover after surgery. Dr. Katie Kangas adds acupuncture, laser therapy and herbs around dental surgery, and has described using the Traditional Chinese Veterinary Medicine (TCVM) formula Yunnan Baiyao before procedures where bleeding is expected. Dr. Ruth Roberts advises checking with your vet about stopping turmeric and ginger before surgery, since both can affect bleeding. These options sit alongside your vet’s pain and recovery plan, not in place of it, and their evidence comes mostly from clinical experience. Ask your vet or a certified rehab therapist when it’s safe to start.

The everyday foundations help too. Fresh, species-appropriate food, a lean body, a settled gut, daily movement and gentle handling practice so vet visits feel less scary all count. We favor biologically appropriate raw food (BARF), because kibble isn’t ideal for the canine species. Raw is best, not required, and lean dogs live longer. See our French Bulldog weight guide, our training guide for calm handling and our lifespan guide for the bigger picture. For older dogs, our senior French Bulldog care guide covers extra pre-anesthetic checks.

If you feed raw. A dog’s strongly acidic stomach, short and simple gut and scissor-like back teeth are why we favor fresh, meat-based food, and dogs have no set need for dietary carbs (Kook et al., 2014; Deschamps et al., 2022; Kayser et al., 2024). Raw isn’t risk-free, though: like any raw meat it can carry germs, so handle it the way you’d handle raw meat for your family. Around a procedure, ask your vet whether to switch to gently cooked or HPP-treated food for a while, especially if your Frenchie is a young puppy or will be on steroids, chemotherapy or other immune-suppressing drugs. Homes with a child under 5, an adult 65 or older, someone pregnant or anyone with a weak immune system should talk with the vet before feeding raw at all (Centers for Disease Control and Prevention). Our raw safety checklist has the details.

Where the Experts Disagree

Vets broadly agree that flat-faced dogs need careful monitoring and recovery. They differ on how much anti-reflux drugs help, whether to combine airway surgery with a spay or neuter, how long to fast, whether flat-faced dogs are really more likely to die and whether anesthesia-free dental cleaning ever has a place.

• Anti-reflux drugs before surgeryA bundled protocol was linked to regurgitation falling from 35% to 9% after airway surgery (Costa et al., 2020). But AAHA says metoclopramide and some other anti-reflux drugs appear to have minimal impact on regurgitation (AAHA, 2020). Our take: ask for a whole anti-reflux plan, not a single pill, and expect it to lower the harm from reflux more than stop it.
• Combine airway surgery with a spay or neuter?Airway surgery was linked to 79% lower odds of recovery complications later (Doyle et al., 2020), and one study found no separate risk from extra procedures (Ree et al., 2016). Yet every extra 15 minutes added risk, and Ree’s team suggests limiting extras. Our take: combining can make sense, but no study has compared it with separate surgeries; let your surgeon weigh the airway grade and the added time.
• How long to fastAAHA says fasts for healthy adults have become shorter and suggests a small meal 4–6 hours before anesthesia for regurgitation-prone dogs (AAHA, 2020). Many clinics still say “nothing after midnight.” Our take: follow your clinic, but ask whether a shorter fast or a small early meal fits your Frenchie.
• Are flat-faced dogs more likely to die?Two deaths in the Ohio State study were both flat-faced dogs (Gruenheid et al., 2018), and Dr. Dodds and Dr. Becker stress the risk. But a 2018 specialist review found no published studies showing higher death rates (Fawcett et al., 2019), and breed wasn’t significant after adjusting for weight in the UK study (Brodbelt et al., 2008b). Our take: the evidence clearly shows more complications, especially in recovery. That’s reason enough to plan carefully.
• Anesthesia-free dental cleaningSome owners choose it to avoid anesthesia. AAHA, the AVDC, the ACVAA and Dr. Morgan all advise against it; AAHA and the AVDC say it can’t treat disease below the gumline, and AAHA notes peer-reviewed data are very limited (AAHA, 2019; AVDC, 2024). Our take: skip it, brush daily and choose a clinic that handles flat-faced dogs well.
