My Dog Cannot Walk And Is Shaking All Over, What Is Wrong With Him?

Seizure and needs to be seen by a vet. I had a dog that did this and it turned out he had cancer. 

I would walk him and he would run around having fun then just fall stiff as if he was dead....it freaked me out to see him come out of it and go on as if nothing. I took him to a specialist and cancer was confirmed. He is at the doggy rainbow now but I gave him the best care possible.

It is having a seizure take it to the vet...

If your dog cannot walk and is shaking all over, then you need to get off the computer and take your dog to an Emergency Vet NOW! Something is seriously wrong and he needs help NOW! Emergency Vets are open 24/7, so you need to take your dog TONIGHT, not tomorrow or the next day. We cannot tell you what's wrong with him because we are not vets. Only a vet can diagnose and properly treat your dog. I can tell you that these symptoms are a "Big Red Flag"! He may have injured himself and that may be why he's not walking and as for the shaking, it's a sign that your dog is in serious pain. Get off the computer, take your dog and GO!
