In between feedings, he often toddles around the box, yelping at the top of his lungs. He did this twice during the night, and the only way to quiet him is to pick him up, soothe him to sleep, and ease him back down with the others. Otherwise, he is sturdy and vigorous, and is gaining weight as are the others. Don't worry, Sheila, we'll take care of this little guy. Thanks very much.
Puppies do get colic.
Sometimes it takes a lot more effort to stimulate a puppy to have a bowel movement or to urinate than the mother is supplying, since she often has multiple puppies to take care of. Rubbing the puppy's stomach gently can be helpful. Using a warm wet washcloth or other soft cloth to gently massage around the puppy's anus can stimulate a bowel movement and relieve discomfort. This can also be done around the preputial area in male pups. It is best not to use the same cloth for stimulating both areas if that can be avoided.
