Purina Has Been Good For My Labrador Retriever

I have a Labrador Retriever. His name is Max. He is 4 years old. I use Purina brand dog food for my dog. I used Purina brand dog food when my dog was a puppy. I decided to use Purina dog food because I saw it advertised on TV a lot and was recommended by my vet. I purchase the dog food from Wal-Mart. I purchase it there because it has the best price. Purina has been good for my dog.
