Hi I am new hear and not strictly a dog owner. I do dog sit my daughters dog who has recently taken ill. Her dog started vomiting the water she drank and as it was hot I took her to the vet because I was worried about dehydration. cutting a long story short the dog has been diagnoses with pancreatitis given drugs and after a three day stay at the vets sent home. The dog still vomits only not so much. She is very quiet and sad looking. This has upset me so much, can any of you experienced dog owners tell me if this goes on for sometime. I wanted to return her to the vets but my daughter says the dog just needs rest.
