My Ripley is in kidney failure and at age 16 is doing well. The first signs were at age 11 when I took him in for his dental - just like Ash. He did just fine and the vet just told me then that his kidney values were a little elevated. It wasn't until a few years later that the levels got high enough that he showed some symptoms. For the past few years all I've had to do for him is take him in for sub-q fluids a couple times a year.

As for diet the vet recommened Purina Pro Plan Sensitive Skin and Stomach because Ripley has a sensitive stomach and throws up easily which makes the kidney failure worse. That food has worked very well and Ripley even gained a much needed pound over the past year and seems to feel better overall.

Hopefully if Ash is in the early stages things will be as easy for him and you as it has been for Ripley and me.

Prayers and positive thoughts on the way.
