Abstract: An interlockable pet collar for preventing an animal from biting or licking the affected injured areas of its body. The interlockable pet collar comprises a multiplicity of open frame structures which can be interconnected to each other to provide an unlimited length of the pet collar. Each open frame structure has three side legs which are integrally formed with a top and bottom legs. One of the three sides legs has two apertures remote from each other. Another one of the three sides legs has two fasteners which are located remote from each and has a distance which is approximately equal to the distance between the two apertures. Each one of the open frames structures is attached to each other by inserting a respective one of the two fasteners to a respective one of the two apertures of another open frame structure, and etc, thereby forming a tubular or cylindrical shaped collar to accommodate an animal's neck.

Abstract: A protective pet collar has two sheets of flexible material fastened around an animal's neck for preventing the animal from bending its neck and thereby biting or licking an affected injured area of its body. The protective pet collar has a width adjustment so that the pet collar can easily be adjusted to accommodate different lengths of the necks of different animals.
