Halo Collar is the consumer GPS dog-fence and dog-tracking product built by Protect Animals With Satellites LLC (d/b/a Halo), founded in 2017 by Ken Ehrman, Michael Ehrman and dog behaviorist Cesar Millan. The product pairs a cellular- and GPS-connected smart collar (currently Halo Collar 5, with Halo Collar 4 still sold) with a companion iOS/Android app that lets an owner draw virtual GPS fences, watch real-time location, trigger Cesar Millan-designed training feedback, and read activity reports. The service runs on a required Pack Membership subscription in Bronze, Silver and Gold tiers that carries unlimited cellular data, an increasing virtual-fence allowance, accessory discounts and third-party partner perks. Halo publishes no public developer program: the app is served by a first-party, undocumented backend at api.halocollar.com (an ASP.NET service that self-identifies as Halo.Web.Api), and there is no developer portal, API reference, OpenAPI/AsyncAPI/GraphQL contract, SDK or webhook surface anywhere on the company's public web properties.
