This dog jumps over your gate & chases your dog so that now it's afraid to go outside? I think you know what you should do! Call the cops or the animal control warden immediately.

That dog is either going to attack some other poor creature (like that little kid) or it's going to get hit by a car if it escapes it's yard again.

Your neighbor shouldn't own a dog if he can't take care of it properly. I would even call your local animal shelter and get them involved.

I feel so bad for your dog! Not to be able to go out in its own yard? Poor thing. I feel bad for that little kid and his dog and I even feel bad for the German Shepard.

Good luck.
