Good advice from Pleng. There are many people, both Thai and Farang who don't share your love of dogs. If your venture proves to be a nuisance for your neighbors, and you're doing it illegally, you'll be lining yourself up for a disaster. Even if you do everything legally, barking dogs can drive many people to do unpleasant things.
My wife and I lived next door to Dawn and her Mom in Takiap, and they had a load of dogs on there property. We knew that when we moved in, and to be honest, the barking never bothered me one bit. Another neighbor however threatened to poison the dogs. A nasty threat, but then again, him and his wife had paid a few million baht for their home where they stayed for about three months of the year. It was bought as a holiday home, and prior to all the dogs, so in a way, one can understand their resentment.
Anyway, good luck, but for your own sake, tread carefully. Things can get nasty here, and I think that's why Richard has suggested that you speak to Dawn since she's seen it firsthand.
