1 dog in 18 homes on our part of the street that I am aware of. I look at dogs like grandchildren. Wonderful to hug (or pet as the case might be) for a short while but then I can give them back to their mother (or owner) until next time. We "babysat" in our home for the 1 dog on the block for 2 days a couple months ago because their owner had a family emergency but that was enough "dog" for us for another couple years. Cute to pet and nice to wave goodbye a few minutes later.
