Can someone help me please? I have a 14 year old Potcake mix and for some reason he's stopped eatting. He hasn't eatten in 3 days can someone tell me what's wrong?

Yeah, you need to take it to the vet. Soon. It could be any number of reasons, but at 14 years of age, it's probably something only the vet can diagnose.

I have never met a potcake mix before. Are you on one of the islands? Do you have access to a vet? I agree with JohnS, you need to take your dog in to see a vet. At that age, when a dog stops doing anything he/she normally does, you need to bring him/her for an evaluation. Please don't wait. If he hasn't eaten for 3 days, something is most definitely wrong.

Yes, the vet, the sooner the better. Even at 14 it could be something simple and easy to cure. When my 12 year old Lab didn't touch her breakfast, I had her at the vet that day, and she was eating in a day or 2. That was almost 2 years ago. We are off for a 2 mile walk and a swim now.
