I have recently experimented with making my own dog cookie treats. I have come across two recipes so far that my dogs love (not that they are picky!). Blogs that deal in the topics of pets and baking can be a great resource to find yummy dog treat recipes. The first was Pumpkin Peanut Butter Dog Treats and they made great stocking stuffers at Christmas. The second is Peanut Butter Bacon Dog Treats which I just spent some time whipping up on this very rainy day. Both recipes have natural, healthy human grade ingredients and little to no added refined sugar which can always be tweaked to your liking or replaced with a more natural sweetener such as honey.
Give them a try. I think you will love them and your dog will love you even more for them. Just remember to check with your vet if your dog is prone to allergies and always give treats in moderation.
