How to make homemade dog treats

Most of my dog recipes are made in a food processor for ease. I use it to grind oats as well as mixing up the dough. I have an old 11 cup food processor and it makes making dog biscuits a snap.

This doesn’t mean you can’t make them if you don’t own one. You can mix everything up in a bowl and proceed with the recipe.

If you own a powerful blender, you can use it to break up the oatmeal.

The first step is to grind the oats. Then, the rest of the ingredients are added to the bowl of the processor and everything is mixed until uniform.

Next, roll the dough out and cut shapes. (This is just like making cookies!) Then place on baking sheet and slide into the oven.

My dog is a small breed, so I use a 2″ cutter to make treats for her. If you have big dogs, you may want to make larger biscuits, just remember to add a few extra minutes when baking.

Making dog treats at home is easy and you can make them for half the cost of store bought. This is also a great activity to do with kids (or adults!) who have been cooped up and need something to do.

More dog biscuit recipes

I’ve been DIY’ing biscuits for as long as I’ve had my dog, which is going on 13 years.

Like many dogs, Sugar has a sensitive stomach and homemade dog treats were the best option for her. If your pup has allergies, this is also a great option because you know exactly what is in the food you are giving to your dog.

How to store homemade dog treats

If you live in a cooler, less humid climate, you can store these treats in a cute dog treat jar on the counter for about a week.

Keep in mind there are no preservatives, so they can’t sit out as long as store-bought dog cookies.

Because I live in a warmer, humid climate, I’d only keep them on the counter for a few days, then store in the refrigerator for up to 2 weeks.

You can also freeze them for up to 3 months and take out a few at a time, which is what I do most of the time.

Thanks for stopping by! Have a delicious day 🙂



  1. Nowhere in your recipes do I find Amounts of ingredients. Just a lovely photo of the ingredients in a food processor. This isn’t the only one – ALL of your dog treat recipes do not have ingredients listed. Just photos. What am I missing? Would love to try these for my dog.

    1. Angeline, each and EVERY recipe on the blog has a complete recipe, with ingredients and amounts. Scroll down to the bottom of each post to find the recipe instructions.

  2. Hi, I just realized that the oatmeal can’t the fast one minute kind. Why is that? Do you think it would be okay to try? Thank you.

    1. Hi Mary, you can try it. The recipe won’t be exactly the same because the quick cooking oats get a little mushy. I’m sure your dog won’t care, but I wanted you to know 🙂

    1. Can I add plain Greek yogurt in place of the coconut oil? My furbaby has pancreatitis and a fussy stomach, so we try to stay away from oils and fats.

    1. Hi Chelsea, Because I live in a warmer, humid climate, I’d only keep them on the counter for a few days, then store in the refrigerator for up to 2 weeks.
      You can also freeze them for up to 3 months and take out a few at a time, which is what I do most of the time.

  3. My dog loves these and so do I! She loves mint and will avidly sniff anyone who has anything mint flavored. Now she has her own mint flavored treats. I’ve made these twice and increased to 1/2 cup the mint to use up what I had on hand and she was in heaven. As a time saver I divided the dough in two portions and rolled it out between the parchment. It helps to spray the top sheet with Pam. I used my pizza cutter to portion out treats after baking them. Easy peasy!

    1. This is fantastic, Lissy! Thank you so much for the comment. I’m so happy your dog loves these treats and that they were easy to make 🙂 Rolling between parchment certainly can be helpful and make cleanup quicker! A pizza cutter is brilliant! Bravo!

    1. Hi Katie, Yes you can substitute pumpkin, but it will change the look and texture of the treats. If you don’t mind that, carry on! 🙂

    1. Hi Marri, you mean chocolate mint, as in the herb? Nothing that contains actual chocolate I’m assuming? I would think it should be fine, but ask your vet to be sure, ok?

  4. Hi, out of curiosity instead of using the cookie cutters would you expect these to come out good using a mold? Also instead of the flour could I use all oat flour?
    Thanks so much!

    1. Hi Rosa! I think they would well in a mold, I’ve had a few people do it that way with good results. You can use all oat flour, but the consistency of the dough will be a little coarser. This might actually work in your favor if you’re going to use a mold 🙂
      Please do report back and let me know what it went!

  5. These treats are easy to make and the Schnauzer follows me all over the house for this treat. I did use 1 TBL of coconut oil and 1 of peanut butter and used 2 C of ground oats &1 C of gluten free flour in the same batch. Now they smell so good, I want to eat one.
    My dogs breath is sweet and I don’t mind his kisses now. Great recipe.

    1. Thank you so much, Robbynne! I’m so happy to hear that your boy liked the treats and now he doesn’t have stinky breath 😉

  6. I love the idea of this! I always worry about the potential damage the preservatives and additives in commercial dog treats may cause in the long run!

    I know homemade dog foods need to be carefully calibrated – can I replace the flour with with more oats, or will that skew the nutritional profile (or ruin the finished treats)? A member of my family has celiac disease, so we can’t have anything with gluten in the house…

    1. Hi there! You can absolutely use all oats instead of flour. The consistency will be slightly different, but the recipe will still work! 🙂 Also, there are several dog treat recipes that ONLY use oats on the site, so if you are looking for more, they are here!

  7. I just made 2 batches of these on standard recipe and 1 with peanut butter. I used all oats as one pup is allergic to wheat and all 4 pupsters loved them. I love knowing what is in them and I must say all 4 pupsters LOVED them. May need to make this a monthly Sunday am activity 🙂

    1. Thank you so much! I’m happy you were able to make the recipe allergy friendly for your pups! They are certainly lucky to have you caring for them 🙂

  8. I made these treats and my dog loves them . I didn’t have applesauce, nor thought about substituting pumpkin, so substituted a half cup of a very ripe banana in it. (Normally, she would spit a banana out.) Plus, I added a tsp of peanut butter to make sure she would try the cookie and not be offended by the banana. I backed off on the parsley and mint a bit to see if she could tolerate the herbs. My pup did well without stomach upset!
