I spent all of my life savings on a puppy from a breeder. While he has rock-solid nerves, a great temperament-- I am nearly in over my head with him. He is so enthusiastic, that he is prone to all the "bad dog" things such as jumping, chasing, pawing, rushing to greet other dogs, charging in friendliness-- all horrors if the dog is collossal and you are frail.
I love my dog. As much work as he will require, we are in it for the long haul. Rescue dogs aren't the only really tough dogs to live with and own... each puppy or even adult purchased with cash, with guarantee, contract, etc etc-- all throw us curves.. even really difficult curves, where we need to work with them their entire lives. Yep, makes us envious of those on the board with easy dogs.. and makes us remember when we had easy dogs in the past. But, truth is-- the problem dog loves us just as much, if not more, than the easy dog does... since we invest so much more time and focus into training and working with them.
My heart is forever grateful to all who rescue. Each dog, breeder superstar bloodlines or rescue pooch, can need us to really work hard to train, counter-condition, read, research, etc.
