Monday morning my 13 year old son's border collie was stolen. After 8 hours of searching and thousands of facebook posts and shares they dropped him back off by the highway in front of our house . I know that the odds of this happening again are slim to none but I want to be able to locate him if something like this ever happens again . I thought that a microchip would be the answer until I looked into them and I think that the big trackers that we use on the coon dogs are too big to leave on him all the time. I am looking for recommendations .
