Good information. Owners can also make up dog tags to put on halters and tack in case the horse gets loose far from home and is found by strangers. I like to have my name and phone number on one side and the barns name and phone number on the other as well as the horses name. Fetching Tags does this. They are very nice tags that will not wear out. I have one for my mare.
This is one thing I very stupidly went two months of owning my horse without doing. Thanks for the reminder!!
