I have a 2yr old male pit bull. He stays in a fenced 9x12 pen. He is extremely active and while he eats well, he is gaining no weight. I would say he might weigh 60lbs. As I said, he eats well, but is constantly running from one end of the pen to the other and jumping on and off his house and tossing his water bucket. I'm worried. Could it be worms?
It is possible. Is he underweight? Have him checked by the vet and bring a stool sample to be on the safe side. vetcare
