My 5 year old Pug had his rabies and DHHP shots late afternoon at the vet's. He has since thrown up several times during the night. He's never done this before after his shots. He also had a cyst on his upper leg drained to make sure it wasn't cancerous, but I didn't think that would cause a bad reaction either. He's really not feeling good. Anyone else's dog had a bad reaction to their shots? Should I call the vet?
