The Puppy Course from AAA Playground is one of our most exciting activities for dogs and a great way to complete any training area. Each arch is made from a thick galvanized steel tubing that is covered in Industry Standard thermoplastic coating in the color of your choice. This makes them durable and can withstand the elements of the outdoors. The arches are sold individually or in a set of 6, allowing you to choose the option that best suits your needs. The individual option grants you the ability to start a small course or add to your current one and grow it into a bigger activity. The 6-pack option allows you to set into a snaking pattern, a heart, zig-zags or any other pattern to present an eye-striking design that can double as a fun, challenging course for a dog. The configurations for this dog park component are limitless.
