Have you ever heard of a dog having burgers and pizzas for regular meals? Probably not. It's also probably not a good thing for the dog either to be on such an unhealthy diet. That's what happened to Dennis the Dachshund. Two years ago it weighed 56 pounds - 5 times the size of a normal and healthy dachshund.
Today, after eliminating burgers and pizzas, it lost 75% of its body weight. Dennis' previous human fed him a steady diet of White Castle burgers and pizzas. Then Brooke Burton, a family relative convinced the owner to give him up.
He was so heavy before, he could barely walk without losing wind. Burton put Dennis on a diet of dry food and exercise. Dennis even had to have three surgeries to correct all of its loose skin to avoid tripping over.
Please don't overfeed your dog. And certainly, not with burgers and pizzas!
