Started yesterday. He seemed to be moving slowly and acting off. Then I noticed a bit more of a hunch in his back. Still ate his dinner with his usual gusto. More hesitant to move as evening progressed. He seems to lean more to his right when he is standing. I gave him some Tramadol left from the last episode. I had to work today, so my daughter was watching him. He is the same as yesterday. I don't want to take him to the e-vet as he is comfortable now on Tramadol. I will take him to my vet tomorrow. He would appreciate some magic rayz please.
