My dog won't eat but will drink water she acts like she weak and won't stand up a long period or walk she will take a few steps then lay back down could u help

I'm very sorry. We can't diagnose your dog on the internet. Not even a vet can do that.

If she's not eating, can't stand or walk, and seems to be ill, then you really need to take her to the vet. That's really the only option.

I wish you all the best.
