I want to thank everyone for all the information in this thread. Recently my 12 year old dog Penny was diaganosed with Bladder cancer. Currently she is on Piroxicam (10 mg I think every other day) and an antibiotic and from reading the messages here I have switched her over to a high protein low carb diet. (Innova EVO dog food) I am also giving her 1/2 teaspoon of graviola extract and 1 teaspoon of Flax Seed Oil mixed in her food every day. For ocassional boughts of digestive distress I give her a Pepsid AC... want to make her as comfortable as possible for as long as we can... Is there anything else I should be doing for her??
