The most common hog wire gauge for a fence is 12.5. However, you can choose from a few gauges based on your needs. While 12.5 is a reliable gauge for penning in large, strong animals, 9 gauge is a better option of you have large animals that are easily spooked, such as horses. For smaller animals, like dogs or pigs, you can use a 16 gauge hog wire.

If the fence is on one neighbor’s property, that person is responsible for repairs, regardless of who benefits from the fence more. The other neighbor must keep trees and other obstacles from crossing the property line and affecting the fence. If the fence is directly on the property line, though, who owns a shared fence? Many states have laws that address this issue. Typically, the two property owners would share responsibilities and costs for fence maintenance and repair. You may need a property line survey to precisely determine ownership and responsibility.

You can use pressure-treated wood for a horizontal fence, but you’ll need to purchase a thicker and higher-quality variety to ensure it doesn’t sag or warp after you install it. Use #2 pine grade lumber and boards and thicker dimensional lumber, such as a two-by-six. You’ll also need to use stainless steel or hot-dipped galvanized fasteners, as the chemicals in the treated lumber will cause regular galvanized fasteners to rust. 

The type of horse fence that’s most effective in the short term depends on your budget. Plastic fencing works as a temporary fence idea for those on a tight budget but doesn’t offer as much protection. Pipe fencing can be a short-term option as well. Despite its high cost, you can install and remove it easily if you need to relocate your pasture area.
