I received a list a couple of years ago of recommended dry dog food from my vet, and there were about 50 choices on the list , but most everything had to be purchased through a vets office. Bil-jack select was on the list. Lucklily you can get that from Petsmart. I fed him Bil-jack for at least a year but recently switched to Natural Balance Duck and Potato after I realized I could buy it from a local pet store. It is suppose to be all natural ingredients. He seams to really like it better but probably because it is something different. He has been on that food for about a month. My dog has not shown an improvement from changing his food.
However, about 1 month ago, before I started him on the Natural Balance, I ran completely out of dog food and had to give him some cheap store dog food. It was beneful by purina. He is suppose to be allergic to some of the ingredients in there but he LOVED the food and he was very playful the week he was on the food. He still licked and scratched but at least he did not mope around and sleep all day. He followed me around the house all day and wanted me to play with him.
What is funny is my grandpa has owned dogs all of his life and they eat table scraps, 2 week old moldy food, catch rats and rabbits etc., and his dogs never got sick, in fact they were the most healthy dogs ever. Of course they were outside dogs and get lots of sunshine and vitimin d in their skin. My dog hates to go outside. He takes care of business and comes right on inside and straight to bed.
