Peanut Butter Oat Dog Biscuits

I could not let the Cookie Project go by without a cookie for dogs – in this case my friend’s Bull Terrier, Maya.  I don’t have a dog right now, but I used to have a miniature poodle, Scruffles.  So, I totally get how dogs are major family members and deserve their own treats.

When I was researching cookie cookbooks, I discovered that there was a whole cookbook just for dog cookies!

You Bake 'em Dog Biscuits Cookbook

This book covers all manner of dog biscuits – low-fat treats for overweight dogs, grain-free treats, treats for dogs on special diets, and treats that help with fleas, freshen breath, and give your pooch more energy.

I remembered how much Scruffles liked peanut butter so I settled on peanut butter oat biscuits for Maya, hoping that she’d feel the same.  I switched things up a little bit from the recipe in the book to use only ingredients that I had on hand, replacing the oat bran with rolled oats and simply leaving off the wheat germ.  If I were making these homemade dog biscuits on a more regular basis for my own dog, I would be more concerned with packing my treats full of nutrients; as a gift for my friend’s pup, I went with something easy!

Maya loved these homemade dog biscuits!!  The only way we were able to get her to sit still for the top photo was to keep handing her treats to eat while she was waiting to attack the good stuff.

    Hi Stefani:

    I sure did love this blog on dog biscuits. Maya is adorable. My question to you is how long will these cookies last if I put them in a cookie jar for my dog, Jack?

    • Stefsays:

      Hi Carol, in the book, it says, “When I make a batch of treats, I divide the finished product into quarters. I’ll fill four plastic bags with treats, label them, and put three in the freezer. The fourth goes into the refrigerator for immediate use. I try to keep no more than a week’s supply in the refrigerator.” These biscuits are quite dry (as opposed to some of the other ones in the book that contain liver or fish) and I suspect that they would be fine at room temperature in your jar for a couple of weeks, but the advice about freezing any more than that is still a great idea.

  2. brookesays:

    Does it matter what kind of milk I use?

  3. I know a few dogs that would love these!

  4. jennifersays:

    When I made these after a few weeks they molded. I am assuming they should of been refrigerated

  5. Didisays:

    My pup is going to love these treats. They look so good. Thanks for sharing.

  6. Mary Jo Doolsays:

    These biscuits don’t last a week at my place. My lab mix loves these biscuits in her Kong. I’m making these weekly. All her doggie friends love these treats too! I will be making all her doggie friends these treats for Christmas.

  7. Mary Josays:

    My dog loves these treats. I make them weekly for her.
