I have one rescue.  I didn't know his background, age or behavior.  He was pretty healthy which that was a big plus since I don't have a lot of money.  And my Lil' Man is the most behave breathing thing in my household 
 
 
The special need dogs do require special owners.  I wish I could adopt any dog with any need.  But with three skinkids, three furkids theirs not a lot of time or money in my hand to do so.
