Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! Soft stool in a puppy can have several causes- viral, bacterial, or parasitic infections are common causes in puppies. Sometimes dietary indiscretion or eating something out of the ordinary can cause soft stool too. I would try giving him some plain canned pumpkin (not the pie filling ) in his food for a day or two to help firm it up. If that doesn't seem to help, I would recommend Rocky be seen by his veterinarian. Your vet may want to do a fecal test, so I would be sure to bring a fresh fecal sample with you to the appointment. I hope this helps!
