:confused: my dog started drooling really bad and got bumps all over his body and within a hour they were gone but now his mouth is swollen does anyone know what could have happened?

Sounds like he ate something toxic or that he was allergic to. Have you called your vet?

Still warm enough to have bees and other insects out? It would be best if you go ahold of the vet. If not, try Bendryl, up to 2 mg per pound of body weight. Any sign of not eating or drinking and find a vet somehow quick.
