I put my Taz on the k/d diet about 4 months ago. Although, he still has to have his treats each day. I've been looking for treats that are low in protein, but haven't found any.
Taz's kidney levels have been slowly (very slowly) going up over the past couple years. So I just hope they do not shoot up suddenly on me. He is super skinny (at his heaviest he was 21 1/2lbs, and now is maybe 12lbs) but eats pretty good.

I will hope that the diet helps with Henry's levels and he is around for many years to come with both of his families that love and care for him.
