If I was too sarcastic i am sorry, this thread may have gotten to me. You may have not suggested it but it seem others have. I did not read that the animal is harassing this person. What I read is this dogs owner is an a#%#ole, any owner that says to shot the SOB, should not get the dog back.
The only thing i read was the dog was showing up at the door, and was next to the chicken coop. My guess is the dog knows he is not welcome where he currently lives and is trying to move on.
Rescues up north here have traveled hundreds of miles to the south, bringing dogs up north where we do not have a stray problem. Click on the dog rescue and maybe some good things will happen.
I understand that most people do not feel dogs are special but I am not trying to raise it to a deity. Using google was just to show these animals deserve a chance to prove if they are good or bad. Some have shown to be great animals, with amazing history's.
This dog has one strike against it being a pit bull, but my limited experience with pit bulls are the are great dogs. My guess is if this dog was adopted by the poster, he would be a good dog.
If others would rather shoot something before giving it a chance, please rethink why this is a default reaction. Thats all.
