Hi, I have three Great Danes who were fed on a Premium Brand dog food for many years. For the past three months I had a bitch coming in and out of season continuously. This affected the dog which is shown presently, Grand CH Kochak Quentin Crisp adversely as he lost a lot of weight and I could not keep him in show condition. Four weeks ago I took the plunge and put all my dogs on Black Hawk. I must say I am totally happy. They love it and Quentin has regained his weight and is back in show condition.
