there was the time alex the wonder dog opened the sliding door BY HIMSELF and went for a walk. i got him back cause of the 2 tags, one with my number, which was busy- i was calling for search reinforcements- and the vets, and the vet-god bless her- sent one of her techs to pick him up. and there was a story in the local paper last week, 2 dogs, after their house was broken into, wound up over a mile away from home.-they jumped into a car at a local mickey d's and refused to get out, the cops were able to take them home, and that's how the found the robbery. so my response is 24/7/365, except for baths, then right back on.
maybe a tag with the tag bolted to the collar part itself for mr binks?
