Responsible dog owners control their dogs. It sounds like the neighbor is an irresponsible dog owner, and I would not put my trust in him to control his dogs in the future. Talking to him and warning him is all fine, but you need to act now. A few strands of barbed wire above your current fence or something.
There is no way I would be worried about upsetting a neighbor, who is an obvious repeat offender, when my families well being is at stake.
