Hi, my parents have a Westie which went travelling last week, thankfully it came back after 5 hours, but my parents were totally horrified during this period. A big worry was that it was stolen or wandered off and couldn't find its way home. They live on a farm, they have had the dog for 4 years and it never did this type of thing before. I was wondering if anyone knows about good tracking devices that can be used on a dog, one that is effective and could give them a piece of mind. I would want one that would be able to let the dog wander for any distance etc and one that could work regardless of mobile signal. Does anyone have any advise?
