My dog won't eat and losing weight and won't walk what should I do

Please take him to the vet. You know we can't see him or diagnose him over the Internet.

How is this even a question?

Agreed time to see a vet, there are too many variables for us to even give you a vague idea as to what might be wrong.

Thank u people but sariss

You're welcome regardless. I'm still unsure how, when your dog isn't eating, can't walk, and losing weight... there's any other option other than the vet?

There are so many possibilities that we would only be guessing at this point. It could be anything from a blockage to Lyme disease. The only way you will know for sure is to see your vet. Please keep us posted.
