I had two dogs when I first got sick and I had to part with one of them because she was too hard for me to handle when I was so weak.
She was afraid to go up and down stairs, through doorways, etc. and I became unable to help her. I adopted her out to an eight year old little girl who had been wanting a chihuahua forever. I think they are both happy.
My other little chihuahua is happy to do whatever I am doing and is much smaller and easier to handle.
