My pug, Toby, is 17 years old. He's pretty low energy and has many lumps and bumps over his body. Although all of the lumps are not gone, they are definitely smaller. His energy level is up and he's been able to go up and down stairs as well as trot to his bowl to eat. He loves the taste of his food with the Buddy Guard on it. I'm going to continue using it, and when all the lumps are gone, I'll give it 5 stars.
