This collar is one of the technologically most advanced dog collars available. It helps the dog owner as he can see his pet better in the darkness; and he is also seen by others. The collar can be switched on easily with a touch and can either shine or blink. Due to the integrated d-ring the dog collar is suitable for all standard leashes. It is light reflective and self-illuminating and is driven by a standard button cell (included). Available sizes: 30-40cm, 40-55cm, 55-65cm
