An improved pet safety flea collar which provides a frictional release of the collar when an animal becomes entangled to prevent strangulation of the animal. The collar includes a free end and a flared end having a chamber, sized to receive the free end of the collar such that a frictional engagement is achieved between the free end of the collar and the flared end chamber. The flared end chamber is shaped in the same contour and cross-section as the free end. The depth of the chamber is selected to provide sufficient penetration of the free end to establish the necessary frictional force to withstand scratching and normal movements of the animal while allowing release should the animal pull with sufficient force if tangled by the collar and an object. The material utilized for the body of the collar is a conventional flea collar material that dispenses an insecticide.
