How the comparison works

Your choices are compared with each model’s product details. A missing or conflicting value stays unknown and cannot satisfy a choice you select. The starting order helps you browse; it does not rate real-world performance.

Source dates appear with each link below. A source date does not confirm today's price or stock.

Separate expansion from supplied wire

Maximum acreage describes the maker’s expansion limit. It does not describe the area enclosed by the supplied kit; that depends on wire length and your layout.

Review the complete installation

Check the planned boundary, additional wire needs and collar power arrangement. Confirm the maker’s age, weight and neck-fit requirements. A radio boundary is not a physical barrier; review the installation and training instructions.

Before you buy

Does maximum acreage describe the included kit?

It is the published expansion limit. The included wire length is listed separately, and the area it encloses depends on your layout. SportDOG’s rechargeable kit includes 1,000 ft of wire; PetSafe Classic includes 500 ft with a rechargeable collar. More wire is not acreage. SportDOG suits a longer supplied-wire preference; its expansion rating cannot determine kit coverage. A radio boundary is not a physical barrier. Follow training, installation and collar age, weight and neck-fit instructions for your layout.

Can you choose a system from acreage alone?

You also need a compatible layout, adequate wire, and a collar that meets the maker’s age, weight and neck-fit requirements.

Why is one expansion limit missing?

The fetched Contain & Remote page did not list maximum acreage. It remains unknown and does not satisfy an acreage requirement. Extra wire and collars may be needed.
