Dog collar tags help to identify your pet if it may get lost. All of our dog collar tags come with a free brass nameplate that includes up to 3 lines of information (16 spaces per line maximum). Include your pets name and address, along with a contact number. You can even add an extra line for reward, medical, or vet information. Please provide nameplate information with your dog collar tags order. These American made single-ply nylon products come with a slide to lengthen or shorten easily. The snap closure is much easier and faster than conventional ones. The adjustable dog collar tags simply snaps on or off.
