I truly believe in the micro chip....my parents boxer (Jack) was stolen twice from their business property and both times the stupid people took him to the vet in town, and he scanned him because he knew Jack, and called my parents to see if they had given him away...uhmmmmmmmm no my parents said...and the micro-chip saved him back to us...now they have locks on the fence when they are at their business...sooooooooooo get it really does WORK!
