I have a puggle that had 10 pups 2 yr ago. Had her spayed and now one of her pups is going to have pups. she is going in on the 15th to be spayed no more pups here. esp her daddy is the papa. sides I have an old black lab, she was spayed when we got her, and the other 3. need no more. these 4 eat like pigs. DH leaves the dog food container open if I have to go away for work.
