The present invention relates to dog necklace and, more specifically, to a dog necklace comprising: a dog necklace band； and upper and lower buckles installed on both ends of the dog necklace band and coupled to each other. When an insertion locking means corresponding to the upper and lower buckles is inserted in a state in which the upper and lower buckles are contacted to each other, the upper and lower buckles are slidingly pulled by magnetic force of upper and lower magnets installed on the upper and lower buckles, such that the inner side of the insertion locking means is caught and the upper and lower buckles can be easily locked. According to the present invention, upper and lower buckles (110, 130) installed on both ends of a dog necklace band (2) are installed to be detached. The upper buckle (110) is provided with a rivet-type locking member (38) and an upper magnet (18) with an interval on an inner surface of an upper buckle body (111) formed by cutting a band fitting part (112) into which the dog necklace band (2) is fitted. The rivet-type locking member (38) includes a column part (37) installed on an inner surface side of the upper buckle body (111) and a head part (36) having a larger outer diameter than the column part (37). The lower buckle (130) is provided with a lower magnet (39) on an inner surface of a lower buckle body (131), which is formed by cutting the band fitting part (132) into which the dog necklace band (2) is fitted, to be attached to an upper magnet (18) by magnetic force of each other. The front side lower buckle body (131) of the lower magnet (39) is formed in a length direction to have a ″T″-shaped insertion locking groove (134), into which the locking member (38) is slidably fitted.본 발명은 개목걸이에 관한 것으로, 더욱 상세하게는 개목걸이를 개목걸이 밴드와, 개목걸이 밴드의 양단부에 설치되며 서로가 착탈 결합되는 상하부버클로 구성하고, 상하부버클을 맞댄 상태에서 서로 대응되는 삽입걸림수단을 삽입시키면 상하부버클에 설치된 상하부자석의 자력에 의해 상하부버클이 슬라이드식으로 당겨지면서 삽입걸림수단의 안쪽이 걸려서 상하부버클이 간편하게 걸림 설치될 수 있도록 하기 위한 것이다.본 발명은 개목걸이 밴드(2)의 양단부에 설치
