If you're going to have a dog, you have to do your part to take care of them. Part of that responsibility includes making sure that they remain within your yard or on your property and sometimes this can be difficult to do if your dog is a little escape artist.
The truth is, though, even if your dog isn't an escape artist, they're going to get out and roam eventually. It's just the nature of animals to do that. So, you'll need to keep your dog in the yard somehow and one of the best ways to do this is with an invisible dog fence.
While some people are put off by the cost of installing a traditional fence such as chain link, others can be just as put off by the cost of invisible dog fencing installation if they don't plan on doing it themselves. Having an invisible fence installed professionally isn't cheap; it can run over $1000 or even more depending on the area that you need to cover with it. You can find out more at doggybakery.org.
The cost isn't only in the installation and initial materials, however. Batteries for the collars can cost $50 to $100 per year to make the fence even usable, so there's that cost to consider.
