I wish this person would report back and let us know what happened. When a dog is in trouble like this, there is no good reason not to take him to a vet. Where there's a will, there's a way. When we purchase or adopt our pets, we make an unwritten deal with them o provide the best care for them that we can. This includes taking them to the vet when they are seriously ill and in need of medical care. If we're not able to take them to the vet, then we should not adopt or purchase them. I'm sorry, I don't mean to sound harsh, I'm just stating a fact.

Completely agree. This sounds like it can be serious. Please take him to the VET ASAP
You can't guess what this is. He needs a proper veterinary diagnosis.
Any time a dog lays down like this, will not move, will not eat or drink, then there is something serious going on. Dogs are generally famous for soldiering through all sorts of minor upsets.
Take him to the vet as soon as you are able to.
