Good luck with your purchase. You are being careful and doing your homework. And that's a good thing. It's really hard to get a guarantee of a quiet neighbourhood.
You can purchase a house doing a lot of homework and with the best of intentions. But neighbourhoods are constantly changing, with people buying and selling. Many of us who moved to TV from larger properties were concerned about the close proximity to other homes.
There are many noise problems in TV in addition to barking dogs. Lots of people have TVs on their lanai's and turn them up loud. You can also move next door to a "party hearty" couple, the night people who party into the wee hours. Or the person who gets up at 6 AM and plays loud exercise music on the lanai. You can back on a golf course and have the maintenance equipment occasionally wake you in the morning. I've even heard people living near the town centers complain about the music and the traffic in and out of the town centers.
And in Chatham some people complain about the noise from trains and some find the sound quite pleasant. You can buy a "bark free" home and next month, have a dog move in next door.
Bottom line, in TV you are probably living in close proximity to a lot of neighbours. Of course if there is a problem, most neighbours will try their darndest to co-operate. We're a great bunch of people here.
