If you have a dog that is over 10 pounds that needs to be safely contained then the SportDOG In-Ground Fence is a great option for you. This is particularly true if you have a very large property since the system will provide coverage of up to 100 acres. The collar is comfortable, proven safe, and effective in containment. Here is how it works; while your dog wears the collar and approaches the boundary wire a beep will emit from the collar as a warning. Should your dog continue towards the wire or try to leave the designated space then the collar will administer a harmless static stimulation to further alert your pet to the fact that they are going beyond where they are allowed to be. You will however need to do some simple training in order to help your pet learn these things. First of all when setting up the system you will need to lay the wiring down and test it prior to burying. Once you know the collar is working you can go back and bury the wire or use staples to secure it. As you’re burying the wire you’ll want to place boundary flags around the yard as a visual for you dog to quickly learn where is safe for them.
