Freshen your pup’s breath naturally with these easy DIY dog breath mints made with oats, parsley, and mint. A healthy, homemade treat your dog will love!
If you’re anything like me, you adore dog kisses, but sometimes the breath that comes with them is… less than adorable. After one too many “tuna breath” moments, I decided to make DIY dog breath mints — natural dog breath mints made with simple, dog-safe ingredients like parsley, mint, coconut oil, and oat flour. These homemade dog breath mints are crunchy, minty, and way healthier than the store-bought breath freshener treats that are loaded with preservatives. Think of them as fresh dog breath treats that double as a healthy dog treats recipe.
I wanted something with real ingredients—no weird powders or chemicals—so I started experimenting. Once I realized how easy DIY dog treats for fresh breath could be, I never went back. And bonus: your kitchen smells like a spa while they bake.
Let’s freshen those dog kisses, shall we?
Why These Ingredients Work in Homemade Dog Breath Mints

Oat Flour (Old-Fashioned Oats): I grind old-fashioned oats into flour because it’s gentle on digestion and naturally gluten-free. Most dogs tolerate oat flour well, especially if they can’t handle wheat-based treats. It’s a great base for healthy DIY dog treats.
Fresh Parsley: Parsley is a superstar ingredient for homemade dog treats for bad breath. It’s packed with chlorophyll, which naturally reduces odor-causing bacteria and supports your dog’s oral health.

Fresh Mint: This is where the magic happens. Mint dog treats help naturally freshen breath and give that cooling flavor. I prefer fresh over dried since you get stronger benefits.
Coconut Oil: Coconut oil is a healthy fat that supports skin, coat shine, and digestion. It helps bind the dough and adds a subtle flavor dogs go crazy for.
Egg or Applesauce: Egg binds everything together, but if your dog has protein allergies, unsweetened applesauce works perfectly.
Safety Note
Always check with your veterinarian before introducing new ingredients. Start with small portions, especially if your dog is new to mint or coconut oil.
DIY Dog Breath Mints Recipe

Healthy, minty, and surprisingly easy.
Ingredients:
- 2 1/2 cups old-fashioned oats
- 1/2 cup parsley fresh, finely chopped
- 1/2 cup mint fresh, finely chopped
- 1 egg large (see tip below for dogs with allergies to chicken products)
- 1/4 cup water plus 1 tablespoon to help form the dough
- 3 tablespoons coconut oil melted (unrefined extra virgin is best)
Directions:
- Preheat the oven to 325° F
- Add oats to a blender and pulse to a flour-like consistency. In a large bowl whisk together parsley, mint, egg, water, and oil. Add oat flour and stir to combine. Knead the dough a few times then turn out onto a lightly floured surface.
- Using your hands or a rolling pin, flatten the dough to about 1/8″ thick. Using a cookie cutter or knife cut out approximately 40 (1-inch) breath mints. Place them about 1/4-inch apart on a parchment-lined or non-stick cookie sheet. Bake 35-40 minutes, or until golden and crispy.
- Allow to cool completely before serving. Store in an airtight container.
FAQs: Everything You Need to Know

Can I use dried herbs?
Yes—use 1 tablespoon dried parsley + 1 tablespoon dried mint. Fresh is stronger, but dried works.
Are these safe for cats?
No. Mint and parsley can upset a cat’s stomach. These are dog breath freshener treats only.
Can small dogs eat them?
Yep. Just use a smaller cutter, or break them in half.
Can I make these grain-free?
You can experiment with coconut or almond flour, but you’ll need to adjust moisture.
How long do they last?
- 1 week at room temp (airtight container)
- 2–3 weeks refrigerated
- Up to 3 months frozen
DIY dog breath mints also freeze beautifully—just thaw before serving.

dogs love it!
I substituted chicken broth for water and added a little ham for flavoring. My dog Jax loved it!!
YEAH!!! Thanks so much for the feedback. Please give Jax a pat on the head for me. 🙂
My 17 & 12 year old furbabies LOVE them😁
So glad to hear it!
I want to make these for my 2 dogs. I asked my vet if it’s OK for my one senior dog who has bad breath and he asked me if I had the “guaranteed analysis?” Do you by chance have that?
Thank you so much and looking forward to making these for my 2 girls.
