One of those trackers looks like it's made for a moose, not a dog.
I saw the commercial again. It looks like they are telling you what the future will bring, not what's available now. And as the dog was running off I didn't see an antenna sticking up in the air. But, if the price was low and the device was small it's a great idea. I'd even know if Ruger was under the bed or the coffee table.
Anyway, right now I think I'll just stick with a leash.
