DIY Doggie Breath Mints Recipe

Who doesn’t love dog kisses? Although we’re always eager to receive some affection from our dog, bad breath can cause us to hesitate a bit. Those moments of hesitation mean we’re not pampering our pets as we should! Dogs can get bad breath from plaque build-up caused by infrequent brushing, insufficient water intake, or just from the foods they eat. Our simple DIY doggie breath mints will help get rid of your dog’s bad breath no matter the reason!

Key Ingredients and Why They Work

There are a few crucial ingredients in these DIY doggie breath mints that make them work while keeping them healthy for your dog. First, the oats. Flavored oats are off-limits for dogs, but these old-fashioned rolled oats are fantastic! Look for gluten-free oats to give your pup fiber, vitamins, minerals, antioxidants, and plant-based protein.

Next up, let’s chat parsley. The green leaves of the parsley plant contains chlorophyll, which works to eliminate bacteria. Getting rid of excess bacteria means better breath for your dog! Parsley also happens to be great for your dog’s digestive system, too.

Then, there’s the mint. Mint makes everyone’s breath better, from humans to our furry friends. It will add a nice, light flavor to the DIY doggie breath mints. The smell is soothing to your dogs, too, and it will flavor their breath after they eat one of the treats.

You should also give our DIY doggie toothpaste a try!

Note: Always check with your veterinarian before making any changes to your pet’s diet. Also, please be aware of any allergies your pet may have to specific ingredients. If your dog is allergic to eggs, for example, make sure to omit that ingredient from the recipe! Be sure to avoid ingredients which have caused reactions in your pets in the past. If you are unsure about a specific ingredient found in one of our recipes, introduce the food to your pets in small amounts first.

  • 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)


  • Preheat the oven to 325° F
  • Add oats to a blender and pulse to a flour-like consistency. In a large bowl whisk together diced parsley and 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 mints) mints. Place mints about 1/4-inch apart on a parchment-lined or non-stick cookie sheet. Bake 35-40 minutes, or until golden and crispy.
  • Allow mints to cool completely before serving. Store in an airtight container.


Tip: For dogs with allergies to chicken products, substitute one large egg with 1/4 cup unsweetened applesauce.

    Do i have to keep them in the refrigerator or outside

    • SkinnyMs  June 15, 2015

      Store in an air-tight container. No refrigeration is needed.

  2. Nadua  September 24, 2015

    hi, I've read the mint is bad for dogs, it's like you give them tooth paste, is toxic, is this correct?

    • SkinnyMs  September 25, 2015

      Nadua, We do extensive research on all ingredients added to our recipes to ensure they are safe for dogs. We do NOT recommend giving your dog any food, herb, or otherwise in large quanities. Please check with your vet before making any changes to your dog’s diet. All dogs are different and have different dietary needs, just as us humans do. Here’s an article about natural remedies for dogs that you might find interesting.

      Thank you for the question.

  3. Lynn  November 7, 2015

    Can not get my hands on the coconut oil (we're to far out in the sticks) is there a substitute?

    • SkinnyMs  November 8, 2015

      Hi Lynn, I just updated and added Olive Oil as an option to coconut oil. 🙂

  4. Brittany  February 18, 2016

    What is the shelf life of these?

    • Gale Compton  February 18, 2016

      Hi Brittany, About two weeks at their freashest. 🙂

  5. Leanne Greco  March 7, 2016

    I just made these and they seem really dry and the dough was hard to work with. Any tips?

    • Gale Compton  March 7, 2016

      I would suggest adding a little water until you have a dough that is easy to work with. As you’ll notice, there’s one extra teaspoon of water which made the dough perfect. Could be the altitude or weather, can’t say for sure without being there. Hope this helps! 🙂

  6. Michelle  March 10, 2016

    How many mints a day can a dog below 10 lbs can have?

    • Gale Compton  March 10, 2016

      Michelle, Hmmmm…I recommend asking your vet that question. My dog is 26 pounds and he gets 1-2 treats a day, even for a smaller treat like the doggie mints. 🙂

    • Michele Hopkins  September 1, 2019

      I didn’t quite get the dough type consistency, but I used gloves, rolled balls & flattened them & it worked out well. I did use less mint this time. My beagle passed on recently, but before she did, she wasn’t crazy about the treats when I first made them. I wonder if it was too much mint? Now, less mint, the first dog came by in the neighborhood & loved it!!

    • Teresa C. Walters  September 28, 2019

      How long so these biscuits stay fresh?

  7. Tammi  July 29, 2016

    How many does a batch make?

    • Gale Compton  July 29, 2016

      Tammi, Depends on what you’re referring to. This recipe makes a batch of about 40 cookies.

  8. Betty  November 2, 2016

    If I were going to make these as pet Christmas gifts, would it be best to refrigerate them until I give them out?

    • Gale Compton  November 5, 2016

      Betty, That would be fine. I make them fresh for the dogs in my neighborhood. I would recommend making them no more than a few days before handing them out. Even dogs prefer fresh! 🙂

  9. Jade  November 21, 2016

    Would I be able to use whole wheat flour instead of the oats?

  10. Leslie  December 18, 2016

    Can mint extract be used?

    • Gale Compton  December 18, 2016

      Leslie, Hmmmmm…I can’t say for sure. I prefer to go with the real stuff when it comes to dog recipes. You could google it to see if you find a reliable resource with that info.

  11. Sharon  December 20, 2016

    I couldn’t find parsley so I’m gonna try dry. Sound ok.

    • Kym Votruba  December 21, 2016

      Yes, dried parsley will work. 🙂

  12. Sharon  December 23, 2016

    Thank you Merry Christmas to you and your family.

  13. Sylvia Stanisa  December 24, 2016

    My daughter and my self we made the dog cookies, and she has two and I have one they all love them they wanted more and we said two treat a day. Thank you so much for the recipe. Happy New Year .

  15. Cheri  February 23, 2017

  16. Nikki Brown  February 28, 2017

    Made these today, they turned out great. My pooch love them. Thanks for the recipe.

  17. Natasha  April 28, 2017

    Can I substitute the mint leaves with mint essential oil?
    I’ve been researching ways to use essential oils on dogs and a lot of people have said it makes their dogs happier ^^

    • Nichole Furlong  April 29, 2017

      Hi Natasha, you can definitely substitute mint essential oil. Only a drop will be needed. A little goes a long way!

  18. Angela  May 1, 2017

    Can this dough recipie be frozen & taken out & cooked as required?

    • Emilia Horn  May 1, 2017

      Yes, Angela, it can.

  20. Ruth  June 20, 2017

    Can I use dry mint leaves?

  21. Debbie  June 22, 2017

    Can they be frozen after they are baked?

  22. Lisa  September 30, 2017

    My dogs are allergic to grains, can I substitute coconut flour for the oats using the same quantity?

  23. Diane  October 15, 2017

    Do u melt the coconut oil first?

  24. Erica Myers  November 11, 2017

    Should I use curly parsley or Italian flat leaf. Also, what kind of mint – peppermint or spearmint?

    • Gale Compton  November 13, 2017

      Erica, I used Italian flat leaf and purchased fresh “Mint” leaves. The mint didn’t indicate peppermint or spearmint, just mint. 🙂

  25. Rebecca  November 26, 2017

    Do you have suggestions for a replacement for oats? My dog is allergic to oatmeal?

    • Gale Compton  November 27, 2017

      Rebecca, Whole wheat flour if there’s no allergies to wheat.

  26. Sue Pinsler  December 12, 2017

    Just made them. Dogs are crazy about ‘em! Wish they had a more minty smell though.

  27. Rosa fernandes  December 19, 2017

    Just made these for my dog. He’s allergic to chicken so we have to feed him white fish with potatoes dry food. He’s breath smells like fish. Just gave him one he likes it. Let’s see if it helps his breath..

    • Nichole Furlong  December 19, 2017

      We’re so glad to hear he enjoyed his breath mint! Let us know if it helped his fish-y breath!

  28. Karen  December 21, 2017

    I found the dough to be too dry even with adding a bit more water. It just crumbled when it was handled and rolled. Any suggestions to make it more pliable?

  29. Kate  January 18, 2018

    Easy and dog approved, thanks for the recipe and a shot glass makes for a perfect cookie cutter for these.

  30. Carol  January 24, 2018

    Thank you for the recipe. All three of my dogs absolutely love them!

    • Nichole Furlong  January 24, 2018

      You’re very welcome, Carol! We’re so glad to hear all three of your dogs love the breath mints!

  32. Sarah  January 30, 2018

    Thank you for this recipe. I’m a hit with all the dog owners in my apt. building!

  33. Erica  February 9, 2018

    If I sub oat flour, would it be the same amount or does it make more/less if you grind your own oatmeal?

    • Gale Compton  February 10, 2018

      Erica, I’ve found that even when grinding the oats, it makes the same amount. In other words, 1 cup rolled oats = 1 cup flour.

  34. Alex  April 1, 2018

    My dog is 78 pounds and i was worried that my mold will be to big amounts at a time for my dog. I ordered mine off of amazon. will this amout be to much for my dog? heres the link to my molds:

    GYBest GGT01 Food Grade Large Ice Cube Trays, Silicone Baking Molds, 2-Pack, Red

    • Gale Compton  April 2, 2018

      Alex, That link does not work for me. It is difficult to determine if those molds will work for your dog. Please check with your vet.

      • SHiloh  June 30, 2018

        Waiting for treats to cool..they seem soft, keeping them in oven extra time hoping to crisp a little..any hints on this ? (Assuming they will harden naturally). Thanks for your support & awesome website ??

        • Gale Compton  July 2, 2018

          They can be baked longer for a more crunchy treat. 🙂

  35. Marie  April 5, 2018

    Can you use brown rice flour in place of the oats

    • Gale Compton  April 10, 2018

      Marie, Brown rice flour should be fine as long as brown rice is the only ingredient.

  36. Valerie  April 16, 2018

    I made these and my Dogter LOOOVVEESS them!!

    • Gale Compton  April 16, 2018

      YEAH!!! Valerie thank you so much for letting us know. Send a pic if you get a chance. Would love to see your sweet dog. 🙂

    No one asked if it worked on the dog’s breath?

  38. Jamie Olsen  January 4, 2019

    I just made this recipe. I had to add 3x the water listed in the recipe because the dough was SO dry. 2 of my dogs LOVED them, the 3rd (puppy with bad breath) wasn’t interested. ??

  39. kia  April 11, 2019

    Can you use Coconut flour instead or Chickpea to make it grain free ?

  40. esther morgan  January 21, 2020

    Thanks hun have been trying to findout many mints for my 2 months dogs

    • Nichole Furlong  January 22, 2020

      Hope you enjoy the recipe, Esther!

  41. Donna campbell  April 24, 2020

    My dog is allergic to chicken can I still use eggs

    • Nichole Furlong  April 24, 2020

      Hi Donna, this would be a question better answered by your veterinarian!

  42. Ryder  July 8, 2020

    Can I replace the parsley with more mint?

    • Gale Compton  July 9, 2020

      Ryder, If you dog is OK with a little more mint. 🙂

      • Hailey  July 26, 2020

        Does it matter how big or small you make the treats? Like if the treat is too big will it get the dog sick? Or too small where it won’t work on the dogs breath?

        • Gale Compton  July 27, 2020

          Hailey, I recommend making the size based on your dogs size, tiny, small, medium, etc..

  43. Marni  August 16, 2020

    Thank you! Our little doggies love these cookie treats!They take care of my little yorkie’s very bad breath as soon as she eats one! Ive made them twice now and they’re super easy to make. The second time I was too tired to cut them out and just patted the dough out on a parchment lined cookie sheet and baked as directed. They came out perfectly baked, and I just cooled and cut into 40 little square cookies. Fast and easy and the doggies didn’t mind at all! We grow our own mint and basil, and I have room for a parsley patch, so they cost very little to make. Thank you again for this wonderful recipe!!!

    • Gale Compton  August 17, 2020

      Marni, That is great news! I’m so happy your Yorkie likes the breath mints. 🙂

  44. Emily  September 29, 2020

    Hi! I just have a quick question, are these treats alright for cats to have as well? Thanks!

    • Gale Compton  September 30, 2020

      Emily, This recipe was created for dogs. You may want to ask your vet if the ingredients are also good for cats, I’m not sure.
