Sorry about your unemployment but even so, sorry even more for your dog. Try to work out a payment plan for your dog with your vet. We are dog owners, I'm a trainer - why would we know what in hell is wrong with your dog. Sorry to be harsh but seriously, even vets will not diagnose your dog over the internet why would a bunch of dog fanciers to any better? Which poison or medication should we guess that he got into, there are hundreds of them and the treatment differs from dog to dog. There is a poison control center for pets you can call, it's 35.00 - 55.00 but if you don't know what he got into how would they psychically know what he got into. He could be in liver failure, kidney failure have absorption problems. Frankly I am usually more patient but this is the wrong forum. Get your dog to the vet now and I hope he makes it.
