With the proof you have, the dogs can be considered a nuisance, probably even a dangerous animal, and animal control should pick them up. Here are some things to think about. (My opinion may not be shared by everyone, but I will give it anyway. I can only assume that the laws there are similar to the ones here.) If the dogs are picked up, the owner still has options for getting the dogs back. If he gets them back, he may follow the rules for a few weeks, but I would bet he will just end up letting them free roam again. I doubt he would retaliate against you, from what you first posted, but maybe you should ask the other neighbors to file complaints as well. That way there is more reason for animal control to fix the issue, and less reason for him to point blame at you. Some people seem strange, but harmless and end up being flat out twisted. I guess what I am trying to say is that it more than likely will not be a permanent solution. Also, if the dogs are picked up, they will be given a medical exam, it is protocol. If pellets are found in the animals flesh, the ball game changes. You may very well have the right to shoot an animal in defense of yourself, and your property but that means fatal shot. Pellets are painful, they can cause muscle damage, nick bones and organs and the wounds can become infected. That makes it animal cruelty. Trust me I have seen it first hand and it is heartbreaking. (It was a hunting accident, someone brought their dog in who had been hit with birdshot.) I hate the idea of killing an animal, but I would much prefer that over causing pain and suffering. I would say take the dogs to the next county shelter and drop them off, but if the dogs are microchipped they will just find their way back.
