My dog has cancer. Actually, I've had 2 dogs with 2 different types of cancer. One died soon after being diagnosed with bladder cancer. (The chemo treatments didn't work.) The other was only given 3 to 6 months to live after being diagnosed with canine lung cancer -- but he's happy and healthy 2 years later after I chose a holistic cancer treatment for dogs. Here are the supplements for dogs with cancer that I've used, plus the dog cancer diet that he eats daily.
