Dog fencing is exactly what you need if your dog keeps running out of your yard and getting into/causing trouble. However, if your dog isn't the problem, but other dogs are coming in and destroying your property or picking fights with your dog, you need to approach dog fencing a bit differently. You do use a lot of the same tactics, but some tools are no longer appropriate, while others become more important.
You Can't Use Electronic Dog Fencing With Strange Dogs
First, electronic dog fencing is not going to work with strange dogs that come into your yard; it works only with animals wearing collars tuned to the radio signal emitted by the fence controls. If the problem you're having is other dogs running into your yard, you need a physical barrier to keep them out. You can still install an electric fence for your dog, along with the physical fence, however.
Watch Out for Jumpers
The fence you add has to be tall, taller than a dog can typically jump. Unfortunately, many areas have laws about how tall a fence can be, which means you might have one installed that is tallish, but not enough to stop larger, more agile dogs. Two things you should consider in this case are roller tubes and hedges. Roller tubes are hollow tubes placed along a rod at the top of the fence that freely rotates. Any animal trying to jump over the fence that uses the top of the fence as a grip to help pull themselves over will hit the bar and fall. If you're allowed to plant a fast-growing hedge that obscures the dog's view into your yard, that's another option. You can install tall gates at the entrance to match the height of the hedge.
Do be careful with the type of plants you choose. It's tempting to want cacti with sharp spines by the fence, but you really don't want to hurt the dogs that try to get in. Sometimes they're just eager neighborhood dogs that are friendly (if clueless about the purpose of a fence), and you don't want them badly hurt.
Keep Both Sides of the Fence Clear
Other than that hedge, you really want to keep both sides of the fence clear. You don't want anything there that a dog could use as a step to help get themselves over the fence. Move toys, ornamental rocks, benches, and other items you have away from the fence so that the dog isn't tempted to use those when trying to jump into your yard.
