Dogs have been a major part of my life every time I've been in a situation where I can have one. I have two now, both rescues from horrendous situations. One has been with me for 13 years and spends most of her time next to me wherever I am. The other is young and doesn't even know yet how to be a dog with a human pack leader. It's difficult, but it is so rewarding, so I can relate to your story. Good luck with your new lease on an active, if chaotic, life.
