The dog was out in their front yard again today. She made no attempt to bring it in. It was hot. They have a privacy fenced back yard. What I neglected to say in my first little note when I went to the door -- the adult daughter and boyfriend screamed Mom someone is at the blankity blank door. Lots of yelling inside etc. The dog cowarded down a bit from their yelling. I love dogs but hubby says Do not go over there again. We have a quiet neighborhood and in 5 years this is the first thing that has happened to make me say anything negative about the neighborhood at all. There are no pets running around this neighborhood at all.
Thanks for the suggestions. I give up - just hope that another neighbor says something to them too.
