Q. My 4 month old pit bull puppy is not eating, not moving around like usual and just acting like something is wrong.
A. I recommend getting him in to see your vet right away. Lethargy can be caused by pain or discomfort due to GI upset or injury. He also may have eaten something he shouldn't have and may have an obstruction, have been exposed to a virus or other disease, or ingested or had exposure to some kind of toxin. Your vet will do an exam and labwork to determine the cause of your pup's illness and get him started on treatment as soon as possible.
