Pet Identification is most important. Dog collars with tags  should be worn, however, a cat or dog microchip identification is much more reliable. A dog tag, dog ID tags, dog name tag, pet ID tags, or pet identification tags are small flat tags worn on a pet’s collar or harness.

 Cats may have microchips also, but if your cat is allowed outdoors, train it to wear a CatSafety collar (without) tags. The collar should have your cat’s name and your telephone number (inscribed) to distinguish it from strays.

Collars with dangling tags may endanger cats and all climbing pets and. some owners object to these ID tags because of the sound made as pets move.      Collar-mounted tags or collar name plates, riveted flat or slipped on the collar’s surface are silent and do not protrude and may avoid these problems.

Collar tags are made of a variety of materials. Metal tags usually made of aluminum, steel or brass, have their information embossed, engraved or stamped onto their surface.

Humane societies, government animal care and rescue organizations recommend that dogs and cats wear ID tags, containing information that will enable them to contact a pet’s owner.
 
Identification enables contact with you if your pet strays too far from home. 
Microchip implants, tattooing, when used, and registering the dog’s license number, microchip information, and tattoo number with lost-pet registries are good backups to identify stolen or lost strays found without ID tags but it is always a good idea to include registry ID numbers on engraved dog ID tags as a thorough method to identify a pet.

In this age of mobile phones, pet ID tags showing the pet’s owner’s home and cell phone number make it easy for anyone finding a stray pet to contact its owner.
