If she isn't seeming better by noon tomorrow I'd call your vet. She should at least be drinking water by tomorrow.

Angie had a dental and extraction today. All went well. She came home at 1:20pm. She got up once to change position. She hasn't had anything to eat or drink. She peed shortly before we came home. She will raise her head and respond when talked to. Should I be worried yet? How long do the side effects last?
