Same thing that happened back in December, except this time was more severe. We were outside for 2 seconds last Wednesday about to play and he gets all excited and jumps on his hind legs and twists. When he did that he screamed in pain...absolutely screamed and had zero movement of his back legs. He scooted around the yard on his butt. He kept trying to stand up but kept flopping over. I was home alone and my girlfriend was over an hour away. So a friend came to help me carry him into the car and I brought him to the emergency vet. MRI revealed he had a second stroke in his spine (happened back in December), except this impacted both sides and why he lost all feeling and control of his back legs.
They say he will make a full recovery, however, they aren't sure what caused it the first time or this time. There was nothing evident in his blood test, however, they did another blood test Friday but have not gotten the results back (so guessing they are doing something more substantial. He's slowly been getting some feeling in his back legs, but still no movement of the legs.
