SportDOG Pet Fences are extremely durable products which also give owners the ability to change up the methods of correction. This is particularly useful during the early training phases where the owner is teaching the dog about the boundaries that have been setup. Since they are new and didn’t exist in any prior form it’s best to take your time when educating the dog so that it can learn and understand what the boundary is. For more information about SportDOG pet fences look to the product pages and if you still have any questions or concerns please call us and we’ll walk you through the process of selecting the right pet fence for you and your dog.
