My dog had 4 teeth extracted and its four days she doesn't eat but drinks water. I did notice she spits up water after drinking maybe she is afraid to swallow. Can it be from the tube they put in her throat that is bothering her.
I'd call your vet and check with them. My pup had one tooth remove (but it was one of the big guys, with healthy roots) and was eating and drinking normally by that evening. A call should be free, and a good vet would be happy to tell you whether or not this is normal!
