If you do not have the time to train your pet, or if your pet is totally wild, an underground fence is probably not for you. An underground fence keeps your pet in but will not keep other pets out. If you have a female dog or if other dogs in your neighborhood roam free and like to fight, an underground fence is probably not for you. Underground fences cannot protect your pet without power. If power failures are common in your area, look for a product that contains a battery backup in the transmitter.
Many models come with lights that remain lit unless the connection is broken.
Shave a small patch on the neck of densely coated dogs on a regular basis for the collar correction to work. Be aware that even intelligent dogs who like to escape will test the fence occasionally. Ultimately, it is your choice as to which method works for you. Consider your budget, personal preference, your pet's size and temperament, and local zoning laws. Inc. All rights reserved.
