Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Sometimes dewormers cause an upset stomach leading to diarrhea or even vomiting. I would add a little rice or a small amount of canned pumpkin to his food. If the diarrhea doesn't improve in 1-2 day or if he stops eating or starts vomiting he should see a vet as he is very young. Good luck!
