What is the cause of this paraparesis? The dog drags his left paw which lies extended flat on the floor. He can occasionally and weakly walk on his right hind limb, that is, he bears weight on it.
As at Oct 26, 2016, the owner sent me a video of the dog at home.
He had much improvement in his left hind as he could bear weight more. His right hind bore more weight more times as he walked over 12 feet to pee and poop.
He was much more active and ate. He even barked now.
I advised confinement to 6 ft x 6 ft area, with no wet tiled floors by using newspapers
and videoing his gait once a day. No more long-distance walk across the wet tiles to climb up a high tiled bar and down as seen in the video.
