I have a 9 month old cocker spaniel. The past 3 days he hasn't been eating the way he normally does.He has vomited appromx. 3 times ..clear liquid. I only feed him dry food...he will however eat his treats.His stool doesn't seem to have changed, except for this am when it was somewhat loose. His energy level doesn't seem to have decreased much either.I am concerned about his not eating.Should i change his food? Appreicate any advice ..Thanks!!
