I have a 16 month-old, 71 pound English bull terrier that is on Holistic Select from Eagle Pack. I feed him the Salmon, Sardine, and Anchovy due to an assumed meat sensitivity. Our breeder originally fed the puppies Eukanuba medium breed, and I switched Riley to Holistic Select's Giant Breed puppy food. He went bananas over it when I first fed it to him. Here's a picture of him trying to sneak some more after eating his meal:

But after having some itchy spots and a rash on his nose, the vet suggested eliminating meat all-together if we could. It seemed to work when we switched him to the Salmon, Sardine, and Anchovy, and we have to check the ingredients in all treats we feed him. When I originally decided to switch from the Eukanuba puppy, I e-mailed Eagle Pack and received a response within a few hours. They were very helpful. I've since switched my two Siamese cats to the same formula for cats, and they've been on it for about a month. I've noticed that they are vomiting less. So far so good.
Riley's breeder asked us what food we were feeding him because his coat is so shiny. There's a noticable oiliness to the food from the fish oils, even more so with the cat food.
I have seen some very positive reviews for all of the Eagle Pack foods on Petco's site. You may want to go there for some reviews on the particular food you are deciding on. But I, for one, am very happy with it (would be even happier if it were cheaper

)
