This blue anti-slip martingale dog collar has a space-themed print with stars, planets & galaxies. Martingale style dog collars provide a comfortable but secure collar for your dog. This style of collar has no buckle, but instead slips over the head and sits loosely on the neck. When the control loop is clipped to a leash, it will tighten. This prevents the dog from slipping out of the leash for safety.
