A releasable chest pad including a padding portion designed to form a single structural unit with an outer chest strap part and threaded through chest strap parts on the two sides thereof that fit into loop adjuster frames of the dog chest harness. A lining padding portion coming into contact with the body of the dog, is fixed only to the outer chest strap part by a bearing portion fixing zone for the adjustability of the threaded through chest strap parts. The lining padding portion can be folded up to the bearing portion fixing zone, then after adjusting the length of the threaded through chest strap parts and closing them on the outer chest strap part. The cut ends of the threaded through chest strap parts are covered by the lining padding portion and the bearing strip portion, preventing the cut ends from irritating the chest or neck of the dog.
