For the past few years I have followed a Youtube couple from the Midlands, who travel the world in a converted van, with their cat. They use the "Weenect" GPS tracker, which also makes a version for dogs, called "
Weenect Dogs 2"
The Youtubers are:
The Indie Projects whom you might even have seen on tv fairly recently, when they competed with other couples for a house in the wilderness of Alaska.
They seem to be very satisfied with their tracker, which doesn't seem to bother their cat at all, so I would think that the dog version would be equally comfortable and efficient. Hope it helps.
