Well the dog is gone now. I haven't seen it running loose, I haven't heard it, seen it, anything. I don't know if animal control took it away (it wasn't neutered & I'm pretty sure no license or shots), they got rid of it or it just flat out finally ran away or got killed. Wherever doggie is, I'm sure it's a much better place.
I keep waiting for the kids to be strolling down the street so I can ask them where their dog is. I'm sorry if that's shady, but if they say anything crappy to me, I'm prepared with a "well you just learned a valuable life lesson about responsibility, accountability and being a pet owner". Harsh, but true.
