These tags were made as to serve as a deterrent of any one who may want to remove your GPS collar from your hound. This little tag placed on your favorite hounds GPS collar just may be what convinces that anti hunter who comes across your dog from taking your tracking collar off. Best part is the tags do not rivet on so they can be removed and moved to another GPS Collar strap at anytime. These go great on our Mooks Glow in the dark GPS Collar replacement straps. This here folks is some cheap insurance.
