That little snort your Boston Terrier makes when they’re happy is one of the best sounds in the world. But what about the snort that sounds different? The one that’s wetter, raspier, or just… off?
Knowing your dog’s normal is everything. And when something shifts, even slightly, your gut usually knows before your brain catches up.
Boston Terriers are dramatic little creatures by nature. They sneeze for attention, stare you down when dinner is two minutes late, and somehow manage to look personally offended by rain. That’s just Tuesday.
But some behaviors aren’t just personality. Some are signals.
Not every weird behavior means a vet visit, but the ones that linger, worsen, or show up alongside other changes? Those deserve a second look.
Here’s a breakdown of ten Boston Terrier behaviors that should send you reaching for the phone.
1. Scooting Across the Floor
It looks ridiculous. It might even make you laugh the first time. But a Boston dragging their backside across your carpet is almost always communicating something uncomfortable.
Anal gland issues are the most common culprit. These small glands can become impacted, infected, or just plain full, and your dog’s instinct is to relieve the pressure any way they can.
Worms are another possibility. Either way, it’s not something that resolves on its own.
2. Sudden Changes in Appetite
A Boston Terrier turning down food is a red flag. These dogs are notoriously food-motivated, so when they walk away from their bowl, something is wrong.
The same goes for the opposite: suddenly eating everything in sight, including things that aren’t food.
Increased appetite can signal hormonal issues like Cushing’s disease or diabetes. Decreased appetite often points to nausea, dental pain, or something internal. Both directions warrant attention.
3. Excessive Reverse Sneezing (Beyond Their Baseline)
Almost every Boston owner knows the reverse sneeze. That honking, wheezing episode that sounds alarming but typically resolves in seconds.
The key word is typically.
If the episodes are happening more frequently, lasting longer, or your dog seems distressed during them, it’s time to dig deeper. Elongated soft palate issues, nasal polyps, and respiratory infections can all mimic or worsen reverse sneezing.
Reverse sneezing is normal for the breed, but "normal" has a baseline. When that baseline shifts, pay attention.
4. Rubbing Their Face Constantly
The occasional face rub on the couch is cute. The relentless, frantic pawing at the eyes or muzzle area is not.
Bostons are prone to eye problems due to their prominent, shallow eye sockets. Corneal ulcers, dry eye (keratoconjunctivitis sicca), and eye injuries can all cause that frantic face-rubbing behavior.
Allergies are another factor, and they’re surprisingly common in this breed.
Don’t wait on eye issues. With Bostons, things can escalate quickly.
5. Tilting or Shaking Their Head Repeatedly
A quick head shake after a bath is normal. A dog who keeps shaking their head throughout the day, tilting to one side, or scratching at one ear repeatedly is telling you something.
Ear infections are common in any dog. In Bostons, their relatively compact ear canals can trap moisture and debris, creating a perfect environment for bacteria or yeast.
Left untreated, ear infections can become serious, and painful.
6. Labored or Noisy Breathing at Rest
Bostons are a brachycephalic breed, meaning their flat faces create built-in breathing challenges. Some noise is expected.
But there’s a meaningful difference between their typical snuffling and breathing that sounds like a struggle.
If your dog is breathing loudly while resting, sleeping with their neck stretched out to open the airway, or seems to tire quickly on short walks, those are signs of brachycephalic obstructive airway syndrome (BOAS). It’s manageable, often with surgery, and the sooner it’s addressed, the better the outcome.
7. Limping or Favoring a Leg
Bostons are athletic, bouncy, and sometimes not the most graceful jumpers. A brief limp after leaping off the couch might resolve itself within minutes.
A limp that persists past 24 hours? That needs to be seen.
Patellar luxation (a slipping kneecap) is especially prevalent in Boston Terriers. It can range from a minor annoyance to something that requires surgical correction, and catching it early matters.
8. Unusual Bathroom Habits
Changes in how, when, or how often your Boston goes to the bathroom cover a wide range of possible issues.
Straining to urinate or defecate, blood in the urine or stool, sudden accidents in a house-trained dog, or going far more (or less) than usual are all worth reporting to a vet.
Some of these signal infections. Others point to blockages, kidney issues, or gastrointestinal problems. None of them are a "wait and see" situation.
When a house-trained dog suddenly starts having accidents, the first assumption should never be behavioral. Rule out medical causes first.
9. Lethargy That Doesn’t Match the Day
Every dog has lazy days. Bostons especially love a good couch sprawl, and nobody should panic over a sleepy afternoon.
The behavior to watch for is unexplained and persistent lethargy. A dog who was bouncing off the walls yesterday and today won’t get up for a walk, won’t engage with toys, and just seems flat.
Lethargy is one of the most nonspecific symptoms in dogs, which also makes it one of the most useful. It often shows up before other symptoms do.
If it lasts more than a day or two, especially paired with anything else on this list, call your vet.
10. Sudden Behavioral Changes or Aggression
A Boston who’s suddenly snapping, growling, or reacting aggressively is almost always in pain. This one gets misread more than almost any other symptom.
People assume it’s a behavioral problem, or that the dog "just got mean." In reality, an animal who can’t verbalize that something hurts will communicate it the only way available to them.
Sudden behavioral shifts, especially in a dog with no history of aggression, should be taken seriously as a medical concern first.
What to Track Before Your Vet Appointment
Noticing a behavior is step one. Documenting it makes your vet’s job significantly easier.
Keep a Simple Log
Jot down when the behavior started, how often it’s happening, and whether it’s getting better or worse. Even a few notes in your phone can help your vet identify patterns.
Video It If You Can
Some behaviors (like reverse sneezing, limping, or seizure-like episodes) don’t perform on command in the exam room. A short clip is worth more than the most detailed verbal description.
Note Any Other Changes
Appetite shifts, water intake, energy levels, sleep patterns. Vets are essentially detectives, and the more clues you bring, the faster they can connect the dots.
Trusting Your Gut as a Boston Owner
Living with a Boston Terrier means learning their language. Their snorts, their stares, their moods, their quirks.
You know what’s them and what’s off. That instinct is a tool. Use it.
A vet visit for something that turns out to be nothing is always better than waiting too long on something real. These dogs give us so much personality, so much entertainment, and so much love that staying ahead of their health is genuinely one of the best things we can do for them.
When in doubt, call. Your vet would rather hear from you.
