Mindex,
As a member of a rescue group who evaluate over 400 dogs a year - There is a dog out there just waiting for a forever home from you. You can choose from puppys, young ones, senior dogs, high energy spirits, and calm cool couch potatoes. There are pure breds, funny crosses, and some truly great All American Mutts. Get to know the rescue groups in your area and nationwide. There are several on this board and many will help you find the breed or size you decide on. They will also guide you as to the characteristic s of their breed if asked.
Good Luck - when you are ready. And hang around this board, the people are great and understand and love their dogs.
