Claim:
A dog training collar comprising: a plurality of releasable interconnecting links connected together to form a string of links having opposite ends; a tensioning member connected between said opposite ends of said link string to form a collar; a releasable fastener releasably connected between said tensioning member and at least one of said opposite ends of said link string; said interconnecting links each include an inner side and outer side where said inner side includes: a pair of spaced apart v-shaped protrusions linked only at their respective lower distal ends by a thickened body frame of the interconnecting links with no other physical connection between the pair of spaced apart v-shaped protrusions from their respective vertex that define an apex of the pair of spaced apart v-shaped protrusions to the thickened body frame, forming a void space in between the pair of spaced apart v-shaped protrusions; whereby said string of links is placed around a neck of a dog with said v-shaped protrusions directed toward the neck and connected to said tensioning member by said releasable fastener to form said collar such that adjustment of said tensioning member when worn causes a physical correction to be applied to the neck.
