If your dog comes running the second you open the peanut butter jar, this roundup is for you. Oats and peanut butter are a classic homemade dog-treat combo: simple, pantry-friendly, and easy to turn into biscuits, bites, and crunchy cutouts. Before baking, always check that your peanut butter is xylitol-free, since xylitol can cause dangerous low blood sugar in dogs and, in severe cases, liver failure. Peanut butter should also be fed in moderation. AKC ASPCA
