Hello everyone. This is my first post. Something really weird happened to my 5 week old female puppy (out of a litter of 6). Her back legs went out. She hasn't lost her appetite nor does she seem to be in pain. She continues to play and be energetic and can stand and give a few steps before her legs give out. I'm not sure what's going on as she was perfectly fine and all of a sudden this. Any advice is greatly appreciated. I am planning on taking her to the vet on Saturday.
