My 6 year old rottweiler killer is diabetic. He was on that science diet crap but that made him shed like crazy and it was too expensive plus I had to go to the vet all the time to buy it. I started consulting with Julio Ferrari at the paws depot and he put killer on LEGACY BY HORIZON. KILLER LOVES IT AND ITíS LESS EXPENSIVE THAT SCIENCE DIET, BUT DO U NO IF THERE IS ANY CHEAPER FOOD THAT I CAN GIVE TO DIABETIC DOG? I pay $65 for a 30 pund bag of legacy at paw depot. Anyone no?
