I have a friend that just has a pup. I think there may be something wrong with this pup and need some input.
He is 13 weeks old and already been wormed twice. His stool is firm and no visible parasites. He is somewhat lazy/calm. He wakes up for food and whines when he is done for more. He swallows it whole and his amount is gone within 1 min and he is whining for more. He is being fed 4 times a day and getting a more than what is called for on the bag.But seems hungry all the time. She is going to start soaking it prior to feeding him so that he does not bloat further But he arrived 2 days ago with this very large and firm abdomen. We immediately thought roundworms and began worming with panacur/albon/flagyl to cover all bases. But nothing in 2 days and stools are still firm.

Then tried infant gas drops thinking gas but nothing.
Now when I say round and large belly I mean his chest is approx. 2 inches wide when standing on hind legs and his abdomen is over 6 inches wide. It is your typical drum sounding taut belly. When I palpate it the hardness does not allow it. He does not cry out or whine with that? I have no advice for this person. I just know it does not look right. Anyone have this before? Ideas besides worms.
Not something she should run to the Emergency vet for but just looking to see if other breeders have experienced this and what am I missing?
