Just checked Canidae has 14% crude fat and 24%Protein. I have one on a low protein diet Science Diet ID but will switch to Royal Canin Hepatic LS 14 (prescription)plus I give him (Avoderm Vegetarian Wet, about 3 to 4 tablespoons a day 7.5% protien and 4.00%Crude Fat). Lots of vegtables and fruit and cottage cheese about a teaspoon a day. Good Luck...Lissette |
