Boston Terrier Benny the Boston Terrier had a signature move. He’d sprint full speed across the living room, launch himself onto the couch, and immediately shove his face directly into his owner’s. Nose to nose. Eye to eye. And breath that could clear a room.
His owner, Maya, loved that little gremlin more than anything. But the morning face-plants had become something to dread. She tried dental chews from the pet store. She tried brushing. She even tried just… accepting it. None of it stuck.
Then she stumbled onto something that actually worked: homemade treats made with fresh, breath-friendly ingredients. Benny still does the couch launch. The nose-to-nose moment is now something Maya actually looks forward to.
If your Boston has been weaponizing their adorable face against you, read on.
Why Boston Terriers Are Prone to Bad Breath
Before we get into the good stuff, it’s worth knowing why your Boston’s breath might be particularly rough.
Boston Terriers are a brachycephalic breed, meaning their flat little faces come with some quirks. Their compact jaw structure can cause teeth to sit closer together than in longer-snouted dogs, which creates more opportunities for plaque and bacteria to build up.
"Bad breath in dogs isn’t just unpleasant. It’s often the first sign that something is happening in the mouth that needs attention."
It’s not a guaranteed problem, but it’s a common one for the breed. Regular dental care matters, and the treats below are a genuinely fun, effective way to make that care part of your dog’s daily routine.
What Makes a Treat "Breath-Friendly"?
Not all dog treats are created equal. Some are packed with fillers, artificial flavors, and ingredients that do nothing for oral health.
The recipes below use real, whole ingredients that dogs love and that actually do something useful. Think fresh parsley, coconut oil, mint, and crunchy textures that help scrub teeth naturally as your dog chews.
The bonus? You know exactly what’s in them.
The 6 DIY Treat Recipes
1. Parsley and Peanut Butter Biscuits
Parsley is a powerhouse when it comes to freshening dog breath. It contains chlorophyll, which is a natural deodorizer, and dogs tend to love the mild flavor when it’s baked into something delicious.
Mix two cups of whole wheat flour, half a cup of oats, one egg, a third of a cup of natural peanut butter (xylitol-free, always), and a small handful of finely chopped fresh parsley. Add just enough water to bring the dough together.
Roll it out, cut into small shapes, and bake at 350°F for about 20 minutes until golden. Store in an airtight container.
Pro tip: Use a tiny bone or paw-shaped cutter and suddenly these feel like a whole event.
2. Frozen Mint and Coconut Oil Bites
These are almost embarrassingly easy to make, and Bostons go absolutely wild for them.
Melt a few tablespoons of coconut oil (let it cool slightly) and mix in a small amount of finely minced fresh mint leaves. Pour into a silicone ice cube tray or a small mold and freeze until solid.
Coconut oil has natural antibacterial properties that can help reduce the bacteria responsible for bad breath. Mint does the obvious fresh-breath work.
"The simpler the ingredient list, the easier it is to make sure you’re giving your dog something that actually helps rather than just tastes good."
One or two of these after a meal goes a long way. Plus, they’re cooling, which your Boston will especially appreciate in summer.
3. Crunchy Apple and Carrot Chews
Texture matters more than people realize. Crunchy treats act almost like a gentle toothbrush, scraping away soft plaque as your dog chomps through them.
Apples (without seeds or core) and carrots are both safe, healthy, and naturally abrasive. Together, they make a great base for a baked treat.
Grate one large carrot and finely dice half an apple. Combine with one and a half cups of whole wheat flour, one egg, and a splash of water. Roll, cut, and bake at 350°F for 25 minutes.
These are dense, satisfying, and the crunch is exactly what you’re looking for. Your Boston will be annoyingly obsessed with them.
4. Chicken and Dill Soft Treats
Not every dog is a power chewer. Some Bostons, especially seniors or those with dental sensitivities, need something softer.
Dill is an underrated breath-freshener for dogs. It’s packed with antioxidants and has a pleasant herbal quality that neutralizes odor without being overwhelming.
Combine half a cup of cooked, shredded chicken with one cup of oat flour, one egg, a tablespoon of plain Greek yogurt, and a teaspoon of dried dill. Mix into a soft dough and press into small rounds. Bake at 325°F for 15 minutes. They should stay slightly soft in the center.
These are genuinely one of the easiest on the list. And the chicken smell will have your Boston doing circles around your feet before they’re even out of the oven.
5. Watermelon and Mint Frozen Treats
Hydration plays a role in oral health too. A dry mouth is a breeding ground for odor-causing bacteria, so water-rich treats can actually help keep things fresher between meals.
Blend a cup of seedless watermelon until smooth. Mix in a few fresh mint leaves (blend those in too) and pour into a silicone mold. Freeze for at least three hours.
"What your dog eats every day adds up. Small, consistent choices are what make the biggest difference over time."
Watermelon is safe for dogs in moderate amounts and the high water content is genuinely good for them. This one is especially great as a summer treat, but honestly, Bostons don’t care about the season.
6. Coconut Oil and Turmeric Dental Drops
Okay, these are a little different from the rest. Less of a "treat" in the traditional sense, more of a small functional bite that you can pop into your dog’s routine.
Turmeric has natural anti-inflammatory and antimicrobial properties. Coconut oil, as mentioned, is antibacterial. Together, they make a surprisingly effective little drop for oral health support.
Melt two tablespoons of coconut oil and stir in a quarter teaspoon of turmeric and a tiny pinch of black pepper (which helps with absorption). Pour into very small molds or just drop small rounds onto parchment paper. Let them solidify in the fridge.
These are small but mighty. One per day is plenty.
One note: Turmeric will stain. Use an old silicone tray and don’t wear white while you’re making them. Ask anyone who has ignored this advice.
A Few Things to Keep in Mind
Homemade treats are wonderful, but they work best as part of a bigger dental care routine. Regular tooth brushing, annual vet checkups, and keeping an eye on what your dog is chewing on all matter.
Also, introduce new treats gradually, especially if your Boston has a sensitive stomach (and many of them do). Start with a small amount and watch for any changes before making something a daily staple.
Fresh breath isn’t just about the smell. It’s genuinely connected to your dog’s overall health. The mouth is where it all starts.
Which Treat Should You Try First?
If you want the easiest possible starting point, go with the frozen mint and coconut oil bites. Two ingredients, no baking, and results that kick in fast.
If you want something your Boston will absolutely lose their mind over, make the chicken and dill soft treats. The reaction alone is worth the 30 minutes.
And if you want to feel like a seriously dedicated dog parent, do the parsley peanut butter biscuits and cut them into little paw shapes. Post a photo. You’ve earned it.
Benny would approve.
