Abstract: An attachment tool for an animal tag is disclosed. The attachment tool includes a first tag interface that mates with a male portion of the animal tag, and a second tag interface that mates with a female portion of the animal tag. The first tag interface and the second tag interface dispose the male portion of the tag in an aligned and opposing relationship with the female portion of the tag while the male portion of the tag is mounted on the first tag interface and the female portion of the tag is mounted on the second tag interface. An arm extends adjacent the first tag interface to at least the second tag interface and the second tag interface is disposed on the arm. A guard extends outward proximate the first tag interface toward the second tag interface. A distal portion of the guard and an opposing structure of the arm proximate the second tag interface define a gap therebetween, the gap extending into a region between the first tag interface and the second tag interface.

Abstract: An identification tag for an animal is provided. The tag includes a male portion defining a shaft, an enlarged portion proximate a first end of the shaft, and one or more sharp edges on a second end of the shaft. The one or more sharp edges are oriented to cut a pathway for the shaft through material contacting the second end of the shaft. The tag also includes a female portion defining a recess. The recess is configured to connect to the second end of the male portion.
