Hot Rod was a 1 1/2 when he had his lp surgery. The first 2 weeks were the worst as it was very upsetting to see him like this. He likes to be held a certain way and of course the leg that was operated on was the one closest to my body. I had to hold him opposite and it was difficult for me to do. Much easier for hubby to hold him.
After 2 weeks, he seemed to be getting better but then it was a matter of trying to keep him from jumping and moving around too much. As the weeks progressed, it got tougher to try and keep him from activity. Hot Rod was on a strict 6 week, no activity recuperation.
He's now 4 and all the vets say that his knee is as tight as could be.
So sorry that you are faced with dealing with this. Hugs.
