About Us

Who We Are

We are Contained K9 – an independent, family owned, underground pet fence installer based in Northern Delaware. We install underground dog fencing in New Castle County and all surrounding areas. In-ground pet 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.

Owner Christos Philippou has been in the dog training industry for years and has worked with many different breeds to accomplish a top-tier level of obedience. Through this type of training, he has learned how to read dog behavior and truly understands dog psychology. This helps with the training aspect for the underground electric fence system and will ensure you are set up for success when training your dog to the system.

We treat our clients’ pets like our own. We want to make this experience as easy and painless as possible, while making the smallest possible imprint in your yard.  Reach out today to discuss your needs so we can help give you one happy pup!
