Potato is looking as spry as ever. You must take good care of the pup. Do you home cook his food? It's the way to go if you care about a clean diet. There's recipes available on the Internet. My daughter uses mostly ground turkey, some carefully selected vegetables, a small quantity of rice and a drizzle of olive oil. In addition, she gives our puppies some minerals an supplements which are available at the pet store. They get a little "junk food" in the biscuits they get as a treat.
