Thanks for your replies. I could never hurt a dog and never will if that is your suggestion please refrain from posting.
I found out it is 2 of our neighbors dogs that come over. (I think I counted 5 or 6 dogs on their proprety once) I cannot catch them because they are 2 skittish. The owners of the dogs have other dogs tied up outside with dog houses and Pomeranians running around in the house (and street occasionaly) so I know they can confine their dogs, they just don't do it well enough with these 2. This has proved to be the most irresponsible owner on the street, everyone else has their dogs in a fenced yard.
I have called Animal Control for my county and I am waiting to hear back. This is not about how good my trash can is, this is about people needing to take resposibility for the animals in their care and me trying to make an effort to help them understand. Just talking to them did not prove effective.
These dogs need to be confined. Strange dogs coming up behind me ON MY property and barking at me does not go over well with me. One did this a few weeks ago when family was over visiting. I don't take things like this lightly.
