I just experienced that with Gizmo yesterday. I took him to the vet and they gave him some medicine nemoxin or something like that, it looks like a mud mask, but he said it tastes ugly,(the vet)..... Luckily Giz passed it in his diarrea poop yesterday. We are okay, his is very very hyper, I think he is trying to make up for lost time yesterday, geeeezzzzz!!
Take him to the vet, better safe than sorry!!Good luck!!
