I have just moved into a new home and everything is in boxes still. At first my six year old Golden seemed fine but the last few days he has been eating very little and seems to be depressed. Hours after eating he will vomit. His stool is solid and he doesn't seem to be ill.
If he only vomited one time, I would not be concerned. If the vomiting and loss of appetite continues, then I recommend a vet visit. This could be from stress. vetcrae
