If he doesn't like the Hill's K/D food, try the Royal Canin low protein/low phosphorous food. Bullitt wouldn't tough the Hills K/D but he loved the Royal Canin canned food. He also got a multivitamin every day along with a fish oil capsule and half a baby aspirin to prevent clots. He didn't get many treats but when he did he got the small Milk Bones twice a day. He did very well on this diet for over a year and a half when we lost him to something totally unrelated to the kidney disease.
