I absolutely understand the "need" for a dog. They are great companions. And I absolutely love taking walks with my beastie. I think that you've given it some thought, which I really respect. Lots of people are too impulsive about taking on a new pet. They are lured in by the cuteness and they forget about the responsibility that's required.Kudos to you for recognizing that this is an issue that requires a bit more thought.Lots of luck finding your new furry friend.
