I wonder can't a vet check his sugar.Like a finger stick is what we do in the doctors ofiice, to read the sugar level in a pt . I read a lot about that hypoglycemic. It also sound like some type of seizure. Does your groomer give him meds prior to grooming? I would call them and find out if they gave him something. do they feed him while he's there? It's so scary when they have something happen for the first time. I hope he's feeling better soon.
