I know of another "Big Dog Rescue" that is FAR more reputable than Gentle Giants, it's called Big Dog Huge Paws, they are based in Colorado, and they take excellent care of the puppies/dogs they rescue.
Interesting you can't find the ingredients list on their website but I did find it on Dog Food Analysis (which gave it 3 stars). I would not feed it based on the Beet Pulp, the Menadione, and unnecessary vegetables, and I HATE it when food has unspecified "Natural Flavors" Natural flavors of what?
