My dachshund just started yesterday having back spasms and acting like he can't move his right leg normally .but this morning he seemed fine but when he went outside to pee he couldn't walk back up the steps , but he walks fine sometimes then sometimes he's real stiff , he also sometimes arches his back. He's three years old and I'm so scared of ivdd , I called my vet he said to try rest and go from there... just curious of some input.. thanks
