I use BlackHawk and am seeing some wonderful healthy and happy dogs in my yard. I was a very happy Royal Canin user but as the price kept going up and it was getting harder and harder (now impossible) for me to get the breeder bags I was looking at a change, I am very happy with BH, I am happy with the price, the ingredients, the availability, the dogs love it and I am using less of the product and maintaining a healthier weight range across the board.
I dont see the need for all the questions... the results speak for the themselves.
