Hi! On Saturday my frenchie (Ollie - 2 years old) attempted to jump up on our bed. His first two paws got up but his back two did not so I picked him up and set him on the bed. He didn't fall, yelp, or seem to be in pain. Later that night he started moving more slowly, I had assumed he was just tired. Sunday morning his entire back half was very shakey, he was struggling to walk and get comfortable. We took him to the emergency vet and they said he appears to have torn or strained a muscle. He was prescribed rimadyl and plenty of rest. He has been resting the last couple days, although it does take him a while to get into a comfortable position. He will get up to eat but has no interest in drinking water. He walks very slowly and still appears weak in his back half. Has anyone experienced anything like this? Recommendations are welcome
