Boston Terrier Healthy-looking dogs get sick all the time. That might sound obvious once you say it out loud, but most pet owners operate as if the opposite is true: if the dog is eating, playing, and wagging its tail, everything must be fine. With Boston Terriers especially, that assumption can cost you.
These little guys are masters of hiding discomfort. It’s baked into their DNA. And because they’re so naturally expressive and clown-like, it’s genuinely easy to confuse "acting a little off" with "just being a Boston."
Knowing what to look for before symptoms become obvious? That’s the real game.
1. Snoring and Snorting That Suddenly Gets Louder
Every Boston Terrier snores. That’s just part of the package when you sign up for a flat-faced dog. But here’s the thing most owners miss: a change in the baseline is the actual warning sign, not the snoring itself.
If your Boston has always been a light snorer and suddenly sounds like a freight train, that shift matters.
What It Could Mean
Brachycephalic Obstructive Airway Syndrome (BOAS) is incredibly common in Boston Terriers. It’s a structural issue involving narrowed nostrils, an elongated soft palate, or a narrowed trachea. Most Bostons have some degree of it.
"The dog that’s always been noisy isn’t the concern. The dog whose noise level just changed overnight is the one worth watching."
Weight gain can worsen airway restriction almost overnight. So can allergies, a respiratory infection, or even sleeping in a new position because something hurts.
Don’t dismiss louder snoring as "just a Boston thing." Ask your vet to take a listen.
2. Frequent Pawing at the Face or Eyes
Boston Terriers have those big, gorgeous, slightly-too-prominent eyes. And because of how their skulls are shaped, those eyes are more exposed to the world than most breeds.
Occasional eye rubbing? Normal.
Repeated, persistent pawing at the face or eyes? That’s your cue to pay closer attention.
Corneal Ulcers and Cherry Eye
Corneal ulcers are one of the most common eye issues in the breed. They can develop from something as minor as a poke from a blade of grass. Left untreated, they escalate fast.
Cherry eye (a prolapsed third eyelid gland) is another frequent culprit. It usually looks like a small pink or red lump in the inner corner of the eye. It’s uncomfortable, and dogs will absolutely try to paw it away.
"With Boston Terrier eyes, ‘wait and see’ is rarely the right strategy. Acting quickly is almost always the better call."
Early treatment for eye issues in this breed almost always leads to a better outcome than delayed treatment. That’s not an exaggeration. Get any eye changes checked within a day or two, not a week.
3. Scooting or Excessive Rear-End Licking
Okay, this one isn’t glamorous. But it’s important.
Scooting across the floor occasionally is something dogs do. If your Boston is doing it repeatedly, or if they’re obsessively licking at their backside, there’s usually a reason.
Anal Gland Problems
The most common cause is impacted or infected anal glands. These are small sacs on either side of the rectum that are supposed to express naturally when a dog defecates. When they don’t empty properly, they become uncomfortable fast.
Boston Terriers seem to be more prone to anal gland issues than some other breeds, possibly related to diet and stool consistency. A high-quality diet with adequate fiber can make a real difference.
But here’s what a lot of owners don’t realize: skin allergies can also cause rear-end itching, and Boston Terriers are notoriously prone to environmental and food allergies. So if your vet clears the anal glands and the scooting continues, allergies are the next thing to investigate.
4. Head Tilting or Occasional Stumbling
This one is easy to write off as adorable. Boston Terriers tilt their heads when they’re curious, and they can be delightfully clumsy. So when you see your dog tilt its head or stumble a little, your first instinct is probably to laugh and grab your phone for a video.
Fair enough. But watch for patterns.
When Neurological Warning Signs Hide in Plain Sight
A head tilt that persists (not just the occasional curious head cock) can indicate an inner ear infection, vestibular disease, or in more serious cases, a neurological issue.
Boston Terriers can be predisposed to certain spinal conditions, including hemivertebrae, which is a malformation of the vertebrae that’s more common in screw-tailed breeds. Stumbling, weakness in the back legs, or changes in coordination can be early signs.
"Sometimes the symptom that gets the most laughs is the one that deserves the most attention."
If your Boston stumbles more than once in a short period, or if that head tilt doesn’t go away, don’t brush it off. A quick vet visit can rule out the scary stuff or catch something early enough to make a real difference.
5. Changes in Drinking or Urination Habits
This is probably the most overlooked category on this entire list because it requires you to actually notice something happening in the background of your daily life.
Most people don’t track how much water their dog drinks. Why would they? They just refill the bowl.
But sudden increases in thirst or urination are among the earliest signs of some of the most serious conditions in dogs: diabetes, kidney disease, Cushing’s disease, and urinary tract infections, to name a few.
What "Normal" Looks Like
On average, a healthy dog drinks roughly one ounce of water per pound of body weight per day. A Boston Terrier weighing 18 pounds should drink around 18 ounces. That’s a rough guideline, not a rigid rule, but it gives you a baseline to work from.
If your Boston is suddenly emptying the water bowl twice as fast, or if you’re noticing accidents in the house from a fully housetrained dog, those are signals worth taking seriously.
UTIs in Boston Terriers
Urinary tract infections are more common in female dogs across all breeds, but male Bostons can get them too. Symptoms include straining to urinate, frequent small amounts, or blood in the urine. It’s not always obvious, especially in dogs with dark coats.
Pay attention to what your dog’s urine looks like on light-colored surfaces. Snow, pale concrete, even a paper towel wipe after a grooming session can give you information that’s otherwise invisible.
Why Subtle Signs Matter More Than Obvious Ones
By the time a health issue becomes obvious, it has usually been developing for a while. The coughing, limping, vomiting, and clear signs of pain that send owners rushing to the vet? Those are often late-stage symptoms.
The subtle stuff: the slightly louder snore, the occasional stumble, the new habit of scooting, the water bowl that keeps emptying faster than usual. That’s where the early catches happen.
Boston Terriers are tough little dogs with enormous personalities. They’ll push through discomfort longer than you’d expect because they want to be right in the middle of everything with you.
Your job is to notice what they won’t tell you. Learn their baseline. Watch for changes. And when something feels off, trust that instinct and make the call to your vet. You’ll almost never regret it.
