If your dog could use a little help keeping their breath smelling fresher, these homemade mint and parsley fresh breath biscuits are an easy treat to add to their routine. Made with simple pantry ingredients, fresh parsley, and a small amount of spearmint, they have a naturally fresh aroma without relying on artificial flavors or commercial breath fresheners.
These biscuits are best thought of as an occasional treat rather than a dental treatment. While the herbs can give the biscuits a fresh scent, persistent bad breath in dogs can be associated with plaque, tartar, gum disease, or other oral problems. Regular dental care and veterinary checkups remain the most important ways to support your dog’s oral health.
The recipe is simple to prepare, easy to portion into small biscuits, and convenient to keep in the refrigerator or freezer for later. Just be sure to use fresh culinary herbs in modest amounts and avoid concentrated mint products or essential oils.
Quick Answer
Mint and parsley fresh breath biscuits can be made as an occasional homemade treat for healthy dogs using small amounts of fresh culinary herbs. They may help your dog’s breath smell temporarily fresher, but they should not be used to treat persistent bad breath or replace routine dental care.

- Use culinary herbs in modest quantities.
- Never substitute mint essential oil, concentrated extracts, or flavoring.

- Refrigerate or freeze extra biscuits to maintain freshness.
Fresh Herbs and Dog Breath
Fresh herbs are often included in homemade dog treats designed to give breath a fresher smell. Parsley and mint are particularly popular because of their strong, recognizable aromas.
However, the amount matters. Culinary herbs and concentrated herbal products are not interchangeable. This recipe uses a small quantity of fresh parsley and spearmint rather than essential oils or concentrated extracts.
It’s also important to distinguish freshening breath from treating the cause of bad breath. If a dog’s breath remains unusually strong or unpleasant, especially with tartar, red or bleeding gums, drooling, difficulty chewing, loose teeth, or reduced appetite, a veterinarian should evaluate the underlying problem.
How to Make Mint and Parsley Fresh Breath Biscuits
Ingredients

- 1 cup old-fashioned rolled oats
- 1½ cups plain all-purpose flour
- ½ cup plain, unsweetened applesauce
- 1 large egg
- 1 tablespoon melted coconut oil, cooled
- 2 tablespoons finely chopped fresh curly parsley
- 1 tablespoon finely chopped fresh spearmint
- 1–3 tablespoons water, if needed
Directions
- Preheat the oven to 350°F (180°C) and line a baking sheet with parchment paper.
- Pulse the rolled oats in a food processor until they have a coarse, flour-like texture.
- Combine the oats, flour, applesauce, egg, cooled coconut oil, parsley, and spearmint.

- Mix until a workable dough forms. Add water gradually if the dough is too dry.
- Roll the dough to about ⅛ inch thick on a lightly floured surface.
- Cut into small dog-safe shapes and place on the prepared baking sheet.
- Bake for 16–20 minutes, until firm and lightly golden around the edges.
- Transfer to a cooling rack and allow the biscuits to cool completely before serving.
Serving, Storage & Variations
Start with one small biscuit when introducing the recipe. Smaller dogs may only need a portion of a biscuit.
Store completely cooled biscuits in an airtight container in the refrigerator for up to 2 weeks, or freeze them for up to 3 months. Thaw individual biscuits as needed.
You can use plain oat flour instead of ground rolled oats. Keep the dough consistency in mind and add water gradually.
Do not add additional herbs simply to make the biscuits smell stronger. Avoid peppermint flavoring, mint extracts, essential oils, and other concentrated products.
Common Mistakes
Using Too Much Mint or Parsley
A stronger herbal smell does not make the biscuits more effective. Keep the recipe’s quantities modest.
Adding Essential Oils
Fresh herbs should never be replaced with concentrated mint or peppermint essential oil.
Choosing Sweetened Applesauce
Use plain, unsweetened applesauce and check the ingredient label for unnecessary sweeteners or additives.
Treating Bad Breath With Biscuits
These biscuits can be a pleasant snack, but they cannot replace dental care. Persistent bad breath deserves attention rather than simply being covered up with treats.
FAQ
Are mint and parsley safe for dogs?
Small amounts of culinary herbs are commonly used in homemade dog treats, but safety depends on the plant and quantity. Because concentrated amounts can cause problems, this recipe keeps the herbs modest and should only be served occasionally.
Will these biscuits cure my dog’s bad breath?
No. They may give the breath a temporarily fresher aroma, but they do not treat dental disease or other underlying causes of persistent bad breath.
Can puppies eat mint and parsley biscuits?
Healthy puppies that are already eating solid food can generally have small occasional treats, but portions should be appropriate for their size. Puppies with dietary restrictions or medical conditions should have new treats cleared with their veterinarian.
Can I use peppermint instead of spearmint?
Stick with fresh culinary spearmint for this recipe. Do not use peppermint essential oil, concentrated extracts, or flavoring.
Can I make these biscuits without coconut oil?
Yes. The coconut oil can be omitted, although the texture may change slightly.
How should I store homemade dog biscuits?
Allow the biscuits to cool completely before storing them in an airtight container. Refrigeration helps extend freshness, while freezing is useful for keeping a larger batch for later.
What if my dog’s bad breath is very strong?
Persistent or suddenly worsening bad breath should not be managed only with treats. A veterinary examination can help identify dental disease or another underlying problem, particularly if there are other signs such as swollen gums, drooling, difficulty eating, or loose teeth.
Conclusion

These mint and parsley fresh breath biscuits are an easy homemade treat with a naturally fresh herbal aroma. They use simple ingredients and can be prepared ahead and stored for later.
The most important thing is to keep their purpose realistic: they are a treat, not a treatment for bad breath. Use modest amounts of fresh culinary herbs, avoid concentrated products, and continue your dog’s normal dental-care routine.
If your dog’s breath consistently smells unusually bad, have the underlying cause checked rather than relying on breath-freshening treats alone.
