Comparison method and sources
How this commercial guide compares GPS fences, verifies specifications and handles featured placement.
Who publishes this guide
GPS Dog Fence is published by Known Agency and sells the PawTronic Pro Series 2, which PawTronic ships and supports. That’s why PawTronic comes first here. Competitors with lower prices or features PawTronic lacks stay in every comparison.
What we compare
We compare the listed models using purchase price, required fence subscriptions, boundary options, remote tracking and relevant setup features. We distinguish required plans from optional services and name the exact models so different generations are not mixed together.
The comparison is based on manufacturers’ published information, checked on November 9, 2026. Prices are snapshots and may include promotions. Confirm the current price, selected variant, shipping, tax and plan terms with the seller.
How we compare
We compare every collar on the same points: price, required plan, boundary shape, smallest yard and dog size. Every figure comes from the maker’s own product page, help center or manual, and where a maker’s pages disagree, we use the stricter number. We haven’t run hands-on tests of all the collars yet, and we’ll publish the results here when we do.
Every price and specification is dated, and we don’t give numerical scores. Manufacturer photos show the products.

How the cost illustration works
The calculator adds one listed collar price to the required monthly fence plan multiplied by 12 and the selected number of years. A zero fee means no mandatory fencing subscription in the verified information; it does not mean every service is free.
The illustration excludes optional tracking, accessories, shipping, taxes, replacement hardware and price changes. Halo uses its displayed starting $9.99 monthly price; other billing options or offers may differ. Cost is one decision factor, not a performance rating.
Corrections and product questions
For a product specification, start with the linked manufacturer source and ask that manufacturer to confirm anything unclear. For PawTronic fit or ordering questions, use PawTronic support.
