Nina Ottosson, world renowned innovator and designer of intelligent puzzle toys. Mental activation is so important for dogs and other pets, says Nina Ottosson. The puzzle games are fun and educational, easy to play with indoors or outdoors, and are developed with the dog’s natural movements and instincts in mind. They are designed for the dog to work with problem solving by finding hidden treats/food in different ways. I call them “games” because the owner and the dog are supposed to play together, which strengthens the bond between them. They can be used by dogs of all ages, sizes and breeds, and also by cats, ferrets, parrots and lots of other animals.
