San Antonio, Texas, has animal regulations online in a huge pdf. If you click the link on this page that says Current Chapter 5, it will download. They allow lots of dogs on acerage away from other dwellings.

http://www.sbcounty.gov/accPlease note the huge difference between what is written in any ordinance and what happens in real life. When I caught the injured, lost horse in my yard on a Saturday, ACC for SBCO, a county larger than many of those little northeastern states, told me they could send someone out to get it on Monday, or for sure on Tuesday.
The horse was standing in the yard with me holding a dog leash looped around its neck, so that wasn't practical. Town limits is just a mile away, and we were going to hobble it down there where someone from the local Animal Control was ready to come pick it up. The local AC people rock.
Luckily for the horse, we found the owner in a few hours after hubby called everyone we knew locally and asked them to call everyone they knew to see if anyone had lost a horse.
It is a good thing my boss was so understanding. Not everyone would believe someone calling in "sick" because they had to hold onto a horse.
