Both of my beagles are rescues and I think both were abused and not socialized. I also had two rescue Greyhounds, one of which was terribly neglected and abused before the rescue group saved him. They have amazing hearts and an amazing ability to forgive what humans from their past had done to them. Of course they have issues - house breaking, not able to be crated, fear of some humans etc. For my husband and me the challenges we have gone thru with these dogs is worth it to have them in our lives.
