- contained K9
Contained K9 is a privately owned and operated underground electric pet fence company operating in the greater Northern Delaware area. They offer an affordable alternative to other companies, such as Invisible Fence. Since Contained K9 is not a national franchise, they don’t have to pay high fees, which in turn gets passed on to you, the client.
Underground electric pet fences are a great alternative to your standard physical fence while giving your dog the same level of freedom. Some neighborhoods and HOAs do not authorize physical fences, so an underground pet fence may be the perfect option. Plus, an electric fence typically costs a fraction of the investment for a physical fence.
