Allows you to walk 2 dogs at once from the same leash. Nickel-plated bolt snaps & O-ring. Attachment choices are leather or nylon. Nylon is doubled (2-ply), stitched, weather resistant, and comes in black only.
I ordered the 12" nylon coupler(the one that comes in black only) and shocked when I got it because it is so heavy and when hooked on two dogs they have to be side by side at all times. Not to mention that they have to be the same height or it won't work. Way too heavy for dogs under 15 lbs.
