About Us

We are Contained K9 – a premier underground dog fence installer based in Northern Delaware. Think of the Invisible Fence brand, but we are a local, family owned company with better pricing. We install underground pet fencing in New Castle County and all surrounding areas, including Southern Pennsylvania, New Jersey, and Maryland. Underground dog fence systems encourage boundaries and provide your pet with a safe, automatic correction if they attempt to stray. When it comes to safety, convenience, and peace of mind, we are here to exceed your expectations at Contained K9.

You’ve probably heard of Invisible Fence, which is the big national franchise brand for these dog fences. They’ve been around forever, but their services come with a hefty price tag. We established Contained K9 to provide an affordable option that often comes in at a fraction of the price. We provide a better service with a wider range of products that will best suit you and your dog’s needs.

Why Choose Us

We know you’ve heard of Invisible Fence, so why would you choose us at Contained K9? That’s a great question. Invisible Fence is a leader in the electric fence space, however, that comes with a cost as the largest franchise in America. Due to the fact that they are a franchise, they can only install one specific product. This “one-size-fits-all” approach may not be best for you and your dog, so that is where we come in!

At Contained K9, we are not a franchise. We can install any product we want, which often leads to a better experience. Every property, every dog, every owner is different, so why would you want the same product installed for everyone? Let us help you decide what will work best. Not only can we fully customize you’re experience, we guarantee our costs will be more affordable than the competing franchises.

A Variety Of Options

Better Than Invisible Fence™ Brand

Everybody has heard of Invisible Fence™ because of their large, national franchise. However, there’s a slight problem with their business model. They are limited to only installing their branded products, even if they are not the best fit for you, your dog, and your property. Here at Contained K9, we are able to shop around and use a variety of products that we know will be the best possible fit to accomplish your goals. We have established great relationships with several vendors that are at the top of the underground dog fence industry and provide the best quality products.

Our Lifetime Warranty

The products that we install for our customers have been tried and tested. They have stood up to the test of time and consistently and reliably perform as they should. We know that you are relying on keeping your dog safely contained to your yard, so we pride ourselves on installing the best products. With that being said, we understand that technology isn’t perfect. If your system has any faults, we will replace it. We have a lifetime warranty on all of our equipment that install so you can have peace of mind. Everything from the wire in the ground to the collar, we have it covered.

One Size Does NOT Fit All

When you are shopping around for an installer for your underground electric fence, you should ask what options you have. Does the company install a variety of products depending on your yard, the layout you’re looking for, or your dog? Not every home is the same, nor is every dog, so why install the same product for every job? Companies like Invisible Fence ™ are limited to their own product line which is not always the best option. We provide free, custom quotes to all of our potential clients so we can come up with the perfect game plan that suits all your needs.
