The two pictures above are of Quinn when we first adopted her from the Collie Rescue (she is a collie mix). We went in expecting to adopt an adult (since I didn't want the hassle of training a puppy). However, Quinn stole our hearts with her gentle, calm nature (it also helped that she was mostly house trained).
Obviously the kids fell in love with her and their enjoyment of her has only grown.
Lily loves Quin and lays down on her or hugs her regularly. Quinn never seems to mind--if she's done, Quinn will just move. Once when Quinn was on her back under the kitchen table, Lily grabbed a handful of skin and hair and pulled Quinn a few inches--Quinn just lay still, not yipping, nipping, or barking. She is a wonderfully calm dog most of the time--even though she is just shy of 5 months old.
Obviously Seth wanted to show how much he loves Quinn too. You can also get a pretty good idea of how much she has grown in the 2 months we've had her!
