A major goal for me is to learn to inform/educate potential dog owners/adopters/guardians about the benefits, personal and societal, of adopting dogs instead of purchasing them. Have you hit on a winning strategy? Willing to share?
So far the politest thing I've come up with is "have you considered rescue?" but that seems to have limited potential. I've been trying to remember what someone must have said to me when I started thinking about getting a dog.
