The peanut ball is a fitness ball in the shape of a peanut. As the ball is not completely round, but has an elongated shape, the ball is much more stable than a round fitness ball. The ball is also used to strengthen the core muscles of dogs and for animal rehabilitation and therapy. The peanut shaped balls can also be used for dogs, such as the normal rehabilitation balls, with the significant difference that they can be used at the earlier stage of rehabilitation, that is also for animals that do not have such good motor control. They can also be used as a support as they are much more stable than other rehabilitation balls. They can be used on both healthy dogs and animals that have difficulty with correct posture. Our Peanut Ball helps the dog maintain a straight and upright posture and allows them to properly place the front and hind runs. You can use the peanut exercise ball in combination with electrostimulation to get the dog used to a correct posture. The Naturasan peanut ball is also claw resistant. Many dog owners are amazed by the good properties of the peanut ball in dog training and in dog pysio therapy. In the event of a hole or damage, the air slowly escapes without the risk of sudden burst of the ball. A practical hand pump is included with the ball. Note: As the material still expands during the first use, we recommend pumping the ball again with air for 2-3 days until the desired strength is achieved.
