Serious responses please - What to do about neighbor's pitbulls?

There's a young couple (30-40ish) three houses down the road from me. They have a kid and two pitbulls. The dogs are always out on their front porch not tied up and are allowed to roam around if they choose. I used to run up and down the road (it's a small residential road) but quit last summer when I noticed the dogs. They will come out to the road and follow anyone walking or running on the roadway. They've never attacked anyone that I know of but I quit going that way out of an abundance of caution.

I can get over not going that way. But my problem is that I have a three year old son and although my back yard is fenced in, the fence along the road is quite low (only about 3 feet high). I'm afraid one of these days one of those dogs will decide to attack and I don't want my kid to be the victim here.

Should I call animal control and report my concern, go directly to the neighbors in question and tell them of my concern but risk sounding like a bitch, or do I take my chances and not say anything? If I ever see them in my yard, I'm going to shoot them.

My yard, my family's safety, my rules.
