  • Patent number: 4924815
    Abstract: An animal collar particularly adapted for dogs including a relatively flat, wide, belt portion with slide keepers for adjusting the length of the belt portion and providing a loop, due to the doubling of the belt through the keeper portions, with an attachment member through each of the loops through which a continuous leash attachment element is arranged. By applying leash pressure to the continuous element the collar size will be reduced in diameter such that a choking effect is provided for controlling the dog. The connective element may be chain or other materials dependent upon the size of the dog.
