Okay. I would like to know the proper name of these so-called pit bulls. I was often defending them, because the ones I had known were very nice dogs. My children would play with the dog next door and so would my labrador. Then, he started jumping the fence out of his yard. He would always come back bloodied. Last December he came back after two weeks. One of the first things he did was attack a little dog walking down the sidewalk. I had to call animal control and contact the owner of the dead little dog. Animal control talked to my neighbor, but wouldn't do anything about the dog unless he hurts a person. Have heard he had killed one other dog on another street and almost killed another. Until recently he had been chained up. He's been off the chain less and less. He still is very friendly to my dog (we have a chain link fence), but I do not trust him.
Find him when he's out of his yard and shoot him. Tell the cops you were in fear for your life.
That dog will attack your dog or you. Don't take the chance.
Take an ordinary brand new cleaning sponge, soak it in meat gravy , and then compress that sucker into the smallest container you can, down to the size of a golf ball.
Stick it in the freezer overnight.
Run a little warm water on the container, slide out that compressed frozen sponge and chuck it over the fence in the dark,(two or three are better and quicker than one but also more suspicious)
In a week you will have no more dog problem in the neighborhood, and most owners and vets will think the dog just ate the sponge, if they are ever discovered.
My farmer friend says the owner should bury them, which is why he won't shoot them. The trespassing dogs usually swallow the frozen sponge in one gulp.
