Wireless Dog Fence GPS Collar Pet Containment System (Green)
A cheap, genuinely portable virtual boundary that works as a training aid. It is not a fence you'd trust with a dog's life.
Best for: Owners with a large, open, unfenced property who want a soft training boundary for a recall-trained dog under supervision, and who value that it packs into a bag for camping or a cottage.

Excellent escape-artist hardware wrapped around a subscription and a coverage question Canadian buyers have to answer before they click buy.
Best for: Owners of fence-jumpers, sighthounds and door-dashers who live in strong LTE-M coverage areas and are fine paying an annual data fee on top of the collar.
