Chance. I was thinking about getting a dog in the near future, and then I went to Petsmart to fish food when the rescue was there. Her color was what lured me over, but it was her temperment that won me over. She was so well mannered when I walked her! So, I was left thinking "Heh, what's a girl like you doing in a place like this?" and she came home with me a few days later.
Asleep at home, probably my fiance just crated her to go to work.
What kind of training collar, if any, do you use?
