Is it normal

[Jessika]

I would like to add that if the diarrhea continues for an extended period of time, I would take him to the vet because it could be other problems. But in your situation I do feel it is just stress

While it is not normal, only his Vet can determine how serious it is. There
are many causes, but then it's still better to check with the Vet.Why not
just give them a call? Did he just get his puppy shots?
