Peanut Butter and Strawberry Jelly Biscuits - Baked Dog Treat, Large Size To this day I still love a good peanut butter and jelly sandwich on soft white bread So I made a biscuit that smells and tastes just like a great PB&J. Taste it for yourself and see. Naturally sweet and irresistible, my dog Gunny drools every time I open a bag. Grain and gluten free, contains no preservative, no colorings and no fillers.
