I give my dog Purina Pro Plan Renal Function and Doerak the dachshund eats it fairly well, hence 4 stars.
Overall, my 15.5-year-old dachshund eats this reasonably well. Unfortunately, it's kidney food, and it's known that kidney patients sometimes have no appetite for any kind of food. So I have to offer it regularly, and eventually he does eat it. I've also tried other types of meat, but that only worked on the first day and hardly at all after that. Those tins ended up going to the animal food bank.
