I have a 5yr old Staffy who I tried for years to put weight on. He was constantly underweight, and constantly at the vet trying to sort out why, and how to fix it. I started him On Black hawk in September. It will only let me upload 1 picture, so here is an after photo Thankyou so much for a truly amazing product. The difference in him is amazing. We now only go to the vet for weigh ins, and he is at a healthy weight for the first time in his adult life. Love the product, and will never go back!!!!
