One of the most aggravating things a dog owner can deal with is having a fenced in yard, yet there dog still digs their way out underneath. You can plug holes with blocks, boards or whatever else you can think of, but if there is a spot left available to them, they will dig!
One of the best options that will work with the fence you already have to keep your dog from digging underneath is to invest in an invisible fencing system. This type of fence is affordable for most average sized yards and they are fairly easy to install depending on which option you choose to go with.
In invisible fence options, you can go with a wireless version that takes only an hour or two to set up and get running. If your yard is sloped or hilly, you might choose to go with the in ground wired version that you bury along the fence line at the bottom. Either one of these options can prevent your dog from digging underneath the fence to escape.
You can visit sites like www.doggybakery.org and look at different brands like PetSafe, SportDog and more. It will help you find the exact invisible fencing option you need to help keep your dog in their own yard so they will be safe and sound day in and day out, with or without your supervision.
