There was a case in England with a dog that was really overweight, its owners were prosecuted for cruelty. Even though they had to go to court and pay a fine they couldnt understand how they were being cruel as they fed it the food it liked because they loved it. There is a show on tv at he moment called 'I'm as fat as my dog' kind of like 'The biggest loser but for dogs and their owners, the dogs on the show are huge but its no wonder, one man takes his dog to the pub with him and the dog has a pint of beer!!
