I had a neighbor who let his dog run free when I lived outside Minneapolis and also returned the unwanted gifts back to him. I called Animal control several times and it did no good.

I suspect there are a lot of dog owners like that and I suspect there are a lot of pet owners who have no idea that there are people like me who just don't like critters. However, I do like babies
