I would recommend that Gleason get checked out by a vet. Common causes of vomiting in dogs include dietary intolerance, dietary indiscretion, food allergy, intestinal parasites, GI blockage, gastroenteritis, bacterial or viral infection, IBD, pancreatitis, among others. After examination, the vet may recommend bloodwork or x-rays to determine the cause of the vomiting. At the very least, he could receive an anti-nausea shot to give him comfort and you could watch him to see if the vomiting comes back. If it does, then he definitely needs to be re-evaluated to determine the cause.
