Tracerz are scent based location markers to help blind pets navigate their surroundings. Made up of all natural ingredients, Tracerz help blind pets see the world through their sense of smell. However, Tracerz are by no means a cure to blindness. All blind dogs are still going to bump into things, especially when they get excited. The mission behind Tracerz is to minimize the frequency and severity of those collisions and make sure your pet never gets lost within the home.
