Just wondering if anyone's dog has ever suddenly taken ill and gone rapidly down hill in the space of five days. I've got two Rhodesian Ridgebacks and the six year old one started to loose his appetite last Monday. This was unusual as he can shift some food and never usually leaves any. He then started with diarrhea on Wednesday night, I put him straight on chicken and rice. Usually within forty eight hours he'd be fine, but it made no difference and Friday night after I fed him he vomitted. He still had an appetite, but today that to has diminished and he's just sleeping and his breathing has got a little heavy. He's going to the vets tomorrow but in the space of four days I'm amazed at how much weight he's lost. He was a lean dog to start with, but he looks emaciated like on the animal cruelty adverts. Anyone's dog suffered the same symptoms or any advice until I can get to the vets tomorrow.
