The PROCYON egg toy is similar in principle to the Treibball game. The dog should not carry it in its mouth, but should push or roll it. However, unlike regular Treibball, the egg does not simply roll forward, but changes direction unexpectedly due to its oval shape. Therefore, it is suitable for slightly more advanced players who have already mastered handling Treibball. The egg is made from thermoplastic material, so it is soft yet durable at the same time. With a size of approximately 18 cm, it is particularly suitable for small dogs or puppies.
