Tell this guy to install an electric fence wire inside his side of the fence, and put collarrs on his dogs. Otherwise, you'll sue him for the damage they are doing to your property. Get an estimate from a contractor for filling inholes, etc. - in real money terms, not just you and a shovel. You shouldn't have to be filling in the holes, or dropping in wire of rocks or anything. It's his problem. You can set up a trap if he refuses, and wait for his dogs to enter your yard. Dog in a box waiting for a taxi to the pound. THe local humane society may have a dog trap, or you can rig up a crate. You can also complain to the ACO and his boss, the police chief coincidentally, that he needs to get a trap and fix this. Not the answer that you can't catch 'em. they would if they really wanted to... But make THEM be accountable.
