I adopted my dog Ranger (on the left in my avatar) from a former coworker who was going to send him to a shelter. They had gotten him from a shelter and I'm glad that I was able to save him from having to go back. I adopted my dog Emma (on the right, a Lab/Pitbull mix) from a friend's sister who was going to send her to a shelter.
I'm happy to have rescued both of my dogs, and any other dogs I get in my lifetime will be rescued. Unless more dogs fall in our laps like these two did, we're always going to go to a shelter and choose dogs that are least likely to get adopted. No puppies, no popular purebreds, and we'd definitely go for Pits.
