After visiting Pets Mart and speaking with a Nutuo rep. I decided to try the Nutro Ultra puppy food. When I came home I decided to look it up on the internet and have still been concerned ever since. Joey had a very dry coat without any sheen to it. Even the vet commented on how dry it was. This was one of the reasons I decided to try the Nutro Ultra. I have gradually (this is the 2nd bag) and am still mixing the purina puppy chow with it. Joey's coat is shinny and healthy. He seems to have more energy than before. I still have concerns but have decided to closely watch him and leave him on Ultra Nutro for now, but will keep checking out the reports. So far I will have to say we have had very good results with this food. Just don't like the bad reports, even if they are not confirmed to be related to the product.
