All of a sudden my Border Collie has stopped eating.. It started Sunday and Today(Monday) he still will not eat... He adctually vomitted Sunday... I have a vet appointment but they can not see me till Wed. He acts about the same but isn't typical. He will eat treats but nothing else. I even opened a new dog food bag. He is up to date on all his shots and worming.. Nothing has change in the house with pets or us. Not like he isn't active he is a Agility dog and my G/f and I are now assistant trainers and he is active in that also/////ANYONE HAVE ANY IDEAS??

Could he have gotten into the garbage and eaten something he shouldn't have? He could have an upset tummy because of something he ate, or even the stomach flu, just like a person. Just keep an eye on him until Weds. make sure he drinks, and if all he will eat are his treats, then give him those for the time being.

You could also try giving him boiled skinless, boneless, chicken breasts, and see if he will take pieces of those, either alone or mixed with a bit of his food. Also, make sure you keep an eye on him when he goes to the bathroom. Check to make sure there is no blood.

You didn't mention his age, but that is all I can think of right now. I guess all you can really do is wait until Weds. unless he gets worse somehow, and then I would just take him to the vet and sit there until someone will check him out.

Good Luck! :)
