Abstract: This invention relates to an animal collar that is non-irritating and tangle resistant. The collar comprises a flexible collar portion, a lower collar portion, a device for connecting together the ends of the flexible collar portion, and a device for attaching a leash to the flexible collar portion. The permanent shape of the lower collar portion maintains an open configuration to the collar such that forces on the animal's neck are distributed around the neck thus reducing irritation to the animal.
