Caring for Flat-Faced Dog & Cat Breeds

What Every Owner of a Pug, Frenchie, Bulldog, or Persian Should Know

If you share your life with a French Bulldog, Pug, English Bulldog, Boston Terrier, Boxer, Shih Tzu, Pekingese, Persian, Himalayan, Exotic Shorthair, or other flat-faced (medically known as “brachycephalic”) breed — you already know they’re some of the most affectionate, comedic, and lovable pets around.

You probably also know they come with some unique health considerations. Their distinctive squished faces are part of what makes them so beloved, but the same anatomy that gives them their iconic look can also create real medical challenges throughout their lives.

This page is here to help you understand those challenges, recognize the signs of common issues, and partner with us to give your flat-faced family member the longest, happiest, most comfortable life possible.

Why “Flat-Faced” Comes with Health Challenges

The term brachycephalic comes from the Greek words brachy (short) and cephalic (head). It describes breeds whose skulls have been shaped — over generations of selective breeding — to have shorter snouts and flatter faces.

The trouble is that while the bones get shorter, the soft tissues inside the mouth, nose, and throat don’t shrink proportionally. The result is a lot of tissue packed into a smaller space, which can cause a range of issues collectively known as Brachycephalic Obstructive Airway Syndrome (BOAS) — along with several other anatomical concerns.

The good news? With informed care, attentive monitoring, and a great relationship with your veterinarian, flat-faced dogs and cats can lead wonderfully full lives.

Common Health Concerns for Flat-Faced Breeds

Narrowed Nostrils (Stenotic Nares)

Flat-faced breeds often have very small nasal openings, which makes nose-breathing difficult and leads to mouth-breathing and frequent panting. Severely narrowed nostrils can be surgically corrected by a specialist once your dog is past about five months of age.

Elongated Soft Palate

The soft palate — the flap of tissue separating the nasal passage from the mouth — is often too long in flat-faced breeds, causing it to hang into the airway. This is what creates the characteristic snoring, snorting, and reverse-sneezing sounds. In severe cases, it can cause respiratory distress, especially with exercise, excitement, or heat. Surgical trimming can help significantly.

Enlarged Tongue and Crowded Mouth

The tongue can be especially thick and large in some flat-faced breeds (French and English Bulldogs in particular), contributing to airway obstruction. The same compressed face also means 42 normal-sized teeth crammed into a smaller jaw — leading to crowding, food trapping, and early-onset dental disease. Early home dental care and regular professional cleanings are especially important for these breeds.

Narrowed Windpipe (Tracheal Hypoplasia)

The windpipe may be abnormally narrow in some flat-faced dogs. This is especially important to discuss before any anesthetic procedure, since safe anesthesia depends on placing a breathing tube in the trachea. We always factor this into our anesthetic planning for flat-faced patients.

Heat Sensitivity

This is one of the most serious — and most preventable — concerns. Because flat-faced dogs can’t pant efficiently, they overheat dangerously quickly. In the Inland Empire’s hot summers, this matters a lot.

Keep your flat-faced dog cool by:

Avoiding outdoor activity during the hottest parts of the day
Limiting exercise to early morning and evening in warm weather
Never leaving them in a parked car, even briefly
Providing constant access to cool water and shaded, air-conditioned spaces
Watching for signs of overheating: heavy panting, drooling, weakness, vomiting, collapse

Heatstroke in a flat-faced dog is a true emergency. If you suspect it, contact us or an emergency hospital immediately.

Eye Concerns

Shallow eye sockets make the eyes more prominent and vulnerable to injury, ulcers, and dryness. Some flat-faced breeds also develop entropion (eyelids that roll inward, causing lashes to rub the eye) or dry eye, both of which need treatment to prevent permanent damage.

Skin Fold Care

Many flat-faced breeds have skin folds around the nose, face, or tail that can trap moisture, oil, and bacteria — leading to irritation, odor, and infection. Regular gentle cleaning (we’ll show you how) can prevent most issues. Dogs with corkscrew tails may also need extra care under the tail to prevent skin infections.

Allergies and Ear Infections

Many flat-faced breeds are prone to skin allergies and recurring ear infections. If you notice frequent paw licking, head shaking, redness, odor, or scratching, please reach out — these are highly treatable with a thoughtful plan. See our Allergies and Dermatology page for more.

Skeletal and Spinal Issues

Some flat-faced breeds — especially French and English Bulldogs — are prone to joint and spinal problems, including intervertebral disc disease. Maintaining a healthy weight, avoiding excessive jumping, and supporting their joints with appropriate exercise can help reduce strain.

A Note for Flat-Faced Cat Owners

Flat-faced cat breeds — including Persians, Himalayans, Exotic Shorthairs, Burmese, and Scottish Folds — share many of the same anatomical challenges as their canine counterparts, along with a few concerns that are uniquely feline.

If you share your home with a flat-faced cat, watch for:

Breathing difficulties — Noisy breathing, open-mouth breathing, or labored breathing (cats should almost never breathe through their mouths; if yours is, contact us right away)
Eye issues — Excessive tearing, eye discharge, corneal ulcers, and tear staining are especially common in flat-faced cats. The shape of their face makes proper tear drainage difficult, so daily gentle wiping around the eyes is often necessary
Dental crowding — Just like flat-faced dogs, these cats have full-sized teeth packed into a smaller jaw, leading to misalignment, retained baby teeth, and earlier dental disease
Skin fold dermatitis — The fold above the nose can trap moisture and debris; regular cleaning helps prevent irritation and infection
Heat sensitivity — Flat-faced cats overheat more easily than other cats. Keep them in cool, well-ventilated indoor environments, especially during Inland Empire summers
Feeding challenges — Some flat-faced cats struggle with traditional kibble shapes; specialty diets designed for their facial structure (like those made for Persians) can help

One important note: Cats are masters at hiding discomfort, and respiratory distress in cats can escalate quickly. If you notice changes in your cat’s breathing, energy level, or appetite, please don’t wait — give us a call.

For feline-focused care, our sister practice Rialto Cat Hospital next door offers a cat-only environment designed around feline comfort — which can make routine care significantly less stressful for flat-faced cats prone to respiratory issues.

Tips for Loving Life with a Brachycephalic Fur Baby

Keep them lean. Excess weight worsens every single concern listed above. Even a couple of extra pounds can have a big impact.
Use a harness, not a collar. Pulling against a collar puts pressure directly on already-compromised airways.
Stay current on wellness visits. Many issues are easier to manage when caught early.
Be cautious with anesthesia. Choose a veterinary team experienced with flat-faced patients (that’s us).
Consider pet insurance early. Coverage is most accessible when your dog is young and healthy. See our Pet Insurance page for more.
Listen to your dog or cat. Excessive snoring, gagging, blue-tinged gums, or exercise intolerance are signs to bring to us right away.
