These are concerns every would-be owner and current owners should be concerned with.

If you are like me, you’re not a big fan of having a big wet puddle by your feet or in your lap.

I have good news for you…

Do Boston Terriers Drool?

Boston Terriers are not dogs who drool. If your Boston is drooling, there may be a simple reason for the cause, such as seeing food, teething, or they just got done exercising. However, it could be worse, such as a severe health issue.

What Other Boston Terrier Owners Say About Their Boston And Drool

Before I wrote this article, I wanted to get other Boston owners to talk about their dogs.

I posed this question on the Boston Terrier Society’s Twitter account, “Does your Boston Terrier have a drooling problem? Or do they drool at all?.”

Here are some of the responses I received…

  • Wade The Boston Terrier ~ “Wade barely drools. Almost never!”
  • Boston2 ~ “My Bostons have never had a drool problem.”
  • Marty Wynn ~ “Rick seems to drool on a long walk in the cold.”
  • Iindie ~ “Not at all past the puppy stage.”
  • Rich ~ “Only when he really wants what I’m eating.”
  • GG ~ “She only drools when she sees food.”

Non-Threatening Reasons Your Boston Terrier Might Be Drooling

Here are some non-harmful reasons your Boston may be leaving puddles of spit on the floor.



Boston’s are known to be droolers when there is food around. My Boston, Bella, will literally leave a puddle right in front of me when I’m eating something. 

Also, Bella will start to drool when I feed her in the morning and in the afternoon.

This type of drooling does not happen every day, but it does happen on occasion.

And when the drooling does occur, it is a lot. Here is a video of Bella waiting for her food from Sofia…check out the drool on the floor.

Your Boston Terrier can start drooling excessively during exercise.

If you are going on a run with your dog, no matter the breed, they will begin to drool or foam as they try to cool themselves.


If you have a young Boston, there is a good chance they will begin drooling during the teething stage.

This period of teething should end around 6 months when all of your Boston’s baby teeth have fallen out and have been replaced with their adult teeth.

Non-Healthy Reasons Your Boston Terrier Might Be Drooling

Broken or Bad Teeth
Object Stuck In Mouth
Poison Ingestion
Liver or Kidney Disease

Broken or Bad Teeth

I learned broken teeth can cause excessive drooling when Bella was around five years old. All of a sudden, she started drooling a lot.

And the drooling was non-stop. The issue behind all this drooling was her teeth.

She had broken some of her teeth off when she tried escaping from her kennel while we were at work…this is one reason she no longer stays in a kennel. 

We ended up going to the vet over the issue. We were given some medication (I don’t remember what), and after a few days, the drooling stopped.

My guess was after the swelling had gone away. 

Object Stuck In Mouth

Impalement of any kind in your Boston’s mouth can cause excessive drooling as their body tries to extract it naturally.

Poison Ingestion

Poison will cause excessive drooling. If you believe your dog has ingested poison, you can call this FREE poison control number.

This service is run by the American Society for the Prevention of Cruelty to Animals and exclusively deals with poison issues related to pets.

Excessive drooling in the summertime could be a sign your Boston Terrier is having a heat stroke.

If you need tips on keeping your Boston cool to avoid heat strokes in the summer, check out this article I wrote; Seven Signs Your Boston Terrier Is Overheating.


Of course, the classic look of excessive drool on a dog’s face is due to Rabbies…think Cujo.

However, this is highly unlikely in your Boston Terrier.

Other Serious Health Issue

If your Boston is drooling excessively and you can not figure out the reason why you need to go see your vet.

Boston’s are not known to drool, and this can be a sign of several other health-related severe issues like;

  • Respiratory Infection
  • Liver or Kidney Disease
  • Stomach Issues

The stomach issues could be because your Boston ate a physical object that needs to be removed.  

Final thoughts…

If your Boston Terrier is drooling because of exercise, teething, or they are hungry, chances are you have nothing to worry about. This is normal.

However, if your Boston is drooling excessively and you are worried, you should always visit your veterinarian.
