An animal collar includes a cord having a first end and a second end, a first clamp coupled to the cord, and a second clamp coupled to the cord. Each of the first and second clamps defines a first passage and a second passage. The cord extends from the first end, through the first and second passages in each of the first and second clamps, and to the second end to define a closed loop. The first clamp and the second clamp are adjustably coupled to the cord such that a size of the loop is selectively adjustable.
