Simple to make and a great way to know exactly what your dog is eating.
Chop parsley and liver. Add to ground beef and mix to incorporate.
Shape into patties or logs. Whatever your dog would enjoy. Use one of the methods below to bake.
Store in a resealable zip close bag. Use within 3 weeks.
Use a cookie sheet with parchment or wire racks. I'd place a spill guard on bottom of the oven. Bake at 180°-225° depending on your oven for 4-6 hours. Keep checking on them for your first batch and then make a note of how long it took on your recipe. Next time you make them you'll have all the information at hand. Or paw depending on how you look at it.
Place in dehydrator* and run according to your brands instructions.
*I ran my dehydrator (for the 2nd round) at 165° for 3-4 hours.
