My dog has thrown up for three days in a row now, (7 times total). He's developed small bumps all over his body and itching like crazy. Still has the same personality and still will eat, if we feed him. Last year around this time he had the same problem but no bumps and no throwing up, just itching like crazy. We took him to the vet and they said it was allergies and to give him Benadryl. It hasn't helped. Any suggestions as to what's wrong and how to help? We are probably going to take him to the vet, but the soonest we can go is Friday due to our work schedule and vet hours.
