What kind of breed do you have? Thats a lot of fat, yikes. I do keep an eye on my labs because those dogs will eat all day if you let them. I swear when one of them was a pup she ate her body weight in kibble after finding an open bag. She would still be eating it if I hadn't found her. Some breeds just like to eat and sleep so you have to really monitor them. Wow, that kind of sounds like me on Sunday after church.
