Since you have not met the neighbor I would talk to him at some point. The dogs would not even be a subject I would bring up. He might. But I would not mention the dogs in the first meeting.
What to do next would depend on the feeling you got from the conversation about the owner.
You do not want a neighbor has an enemy. But sometimes it happens. I have some stories to tell but they are on going and might lead to court, so I will not tell my story. Yet.
I have young kids. Dogs, or worse, more than two dogs, I do not know, are a threat to my kids. Period. I have only had unknown dogs on our place a couple of times. They have always done the right thing, which was to leave. Quickly.
I was talking to an old Chicken farmer years ago. He was in his 80s at the time. He said farmers in the county would have to get together every few years and shoot stray dogs. The stray dogs would breed into large feral populations and start taking down livestock so the farmers would have to take out the wild dogs.
Our neighborhood had some problem dog owners. Many calls to the Sheriff and animal control. At one point the dog owner had three dogs but I only see one now. Not sure what happened to the other two. One of them used to chase cars. I used to swerve out of the way of the dog but after months of that nonsense I just drove like I was supposed too. The owners knew what the dog was doing and, if the dog miscalculated....
Those dogs came out on the street one day when I was walking with our oldest child and my dog. Thankfully I know how to read dogs and react to them. As it was the dogs almost got shot. They were a bit too aggressive and they were in the street. If my kid had been alone and ran, she easily could have been killed.

I know elderly ladies going for walks were menaced by those dogs which might be why I no longer see two of them. I know the law enforcement told the ladies to shoot the dogs if they had too.
One thing that amazes me about dogs is that they can be shot multiple times and still survive. If you pay attention to the news this happens fairly frequently. A few years ago a deputy in my county responded to an alarm call. Long story short, she was attacked by 3-4 Pit Bulls that almost killed her. Officers responding to her shot 2-3 of the dogs, multiple times, but at most, only one dog died. I never heard the result of the lawsuit.
I certainly would check the laws in your state regarding dogs.
If you choose to carry Pepper Spray be aware there are different types of sprays. Some Pepper is mixed with water and others with alcohol. You want a mix using alcohol. Pepper Spray is an oil. Oil and water does not like to mix, so to use a can of Pepper that uses water as a carrier, you need to shake said can. Will you remember or have time to shake the can?
The other thing to look at is the spray pattern of the pepper. Some sprays are almost a fog while others are a stream. Both have their good points and bad points. A fog is good for a close encounter and is almost certainly going to hit the target. But it is also likely to get you as well. Especially if the wind is towards you. And do you really want to have to wait for something dangerous to get close?
The stream spray shoots much farther which is good or bad. Farther keeps the threat further from you which is good but it is that much harder to hit. Wind makes things that much more interesting.
If you are afraid for your life should you be using Pepper Spray?
Which ever spray type you have, you need to try before use in a real situation. Just note the direction of the wind and spray accordingly.



Unless you want to clear you Sinus. :laughing::laughing::laughing:
