If they are wild dogs, then shoot them. Wild dogs have been known to attack little kids, and there is no reason not to kill them. They are a danger that should not be allowed in your community.

Check with your local police/sheriff's department to make certain that there are no "firearm discharge" laws in your area first. If there is nothing legally stopping you, then organize a very small community meeting, explain the danger, and see if you can find a couple of volunteers to help you track the wild dogs down. You may be able to even get your local law enforcement officers to help if you have an organized small team - see if SWAT team members will volunteer their time. They tend to be a little more gung-ho.
