Lemonbar...regarding your dog.... I have terrible neck, arm, and hand problems too and my dog was an unruly puppy with too much hunting blood in her (long story). I got a harness with a front clip. It creates a situation where pulling is very uncomfortable for them and will actually turn them a bit. Now she walks like a

dream (as long as she has her harness on ;-) I went from barely able to make it around the block to 3 miles a day. It really helped to get out every day and training her on the walks to ignore other dogs, etc. gave me a focus other than myself. I also listen to NPR podcasts

on my walks so it's a treat for me too :-) Finding the supports you need to continue some activities is really crucial I think.
