I have a 13 year old Rat Terrier, her fur was thin, shedded excessively, and had a terrible leakage problem that I was told was incurable and had been giving her Proin for years and years. Well, I cannot believe since feeding her FreshPet for the past month, the leakage has completely stopped, her fur looks healthy and thick, she seems much younger than she is now, her fatty tumors are also decreasing in size ! Thanks for your great pet food !
