I would definately call animal control. Whether the neighbor did it or not, it needs to be reported. If it was the neighbor, by NOT reporting will only make the neighbor that much more bolder next time.

This is a good lesson for everyone. Our dogs are our responsibility. Yes, we can sit back and say well someone else did something. But in the end it is our loved one that is hurt. Better to let them potty on a leash or build some kind of run area where they are kept on your property and nothing else can get to them.

We built a small run for our dogs with some cheap fencing material at Lowe's and some stakes you can just hammer in the ground. It cost us $100 for materials. It isn't something you can leave them out all day in or unsupervised. But it keeps them home and prevents anyone or any other dog from getting to them for enough time that I can go out and bring them in.
