Any fool knows a dog needs a home, a shelter from pigs on the wing

So I'm thinking about getting a dog. I have a friend who has a boxer puppy. Sweetest puppy ever. She's trying to talk me into getting a boxer puppy too. From the boxer rescue society. I have a house, I have a yard, I want a dog ... not sure what my hesitation is, or how i can saw no to the sweet little face of the picture i have of this dog...hmmmmm.
