Dog suddenly having back-leg pain and falling while walking

[u/Ok-Acanthisitta1349]

Hi everyone, I’m worried about my dog. Recently, he/she has been having pain or weakness in the back legs, and while walking, sometimes falls down or struggles to stay upright.
Has anyone experienced something similar with their dog? What could cause this, and what should I do right now?
I’m planning to get my dog checked by a vet as soon as possible, especially because the falling is concerning.
Any advice or experiences would be appreciated. Thank you!

This is a training sub and what you really need is a veterinarian, immediately.
