@nick4 Sounds like an allergy or something biting him. For sure the vets and see what they say. Benadryl for sure, as far as I know it does no harm if you dose correctly.
I agree with Buddys Pal… if they didn't do either urinalysis or xray, I'd get them done. If you have a sick dog and the vet just sort of says "oh well, blood work looks okay".. may be time for a new vet. Something is obviously wrong.
My first girl got carsick. I used Dramamine (Gravol) for her. Luckily she outgrew the problem, because every time I had to pill her the neighbours thought I was killing her. She screamed her head off! (and of course spit out the pill). She did best riding loose in the back seat. That was in the '60s, and we didn't worry about such things…...
