when i took my dog out this morning, we went down the front steps and took a few steps and then he sat down and started to shake. I could not get him to move except for a few steps and then he would sit again. I thought it might be his hips because this has happened once before. So i massaged them and warmed him up and the tried to get him in but he still would not move. So I put the leash under him to walk him in but that only got him a few steps also. I opened the door and called for my dad to wake him up and he came down and told me to drag him in so i pulled him and he sat there then started to move , took a few steps and stared to sit again so i pulled him up the stairs and he walked into the kitchen and sat and shook. I massaged his hips and he stood up and tucked in his tail. He has not gone to the bathroom yet this morning so i will have to take him again soon. If it is his hips which i suspect it is as he has been walking around the last two days with a hunched back, should i just massage them and see if it works, he seems to be in pain when i massage them because he tucks his tail, so should i stop doing it. What can i do to help him?
