This Trax Peanut pet balance platform from FitPAWS is an excellent accessory for exercising your dog and improving its strength, balance, and flexibility. The balance platform, made of professional-grade heavy-duty material, provides superior gripping and resists damage caused by dog nails. It is used for core conditioning of sporting and working dogs and also animal rehabilitation and therapy. The unique shape of the peanut limits its movement to front/back, ideal for dogs who are new to this type of training. You can also adjust the balance challenge by under-inflating, so the ball is not that firm. The surface of the peanut is specially designed to prevent slipping, providing neuro-sensory stimulation. Please note: The platform can be easily inflated with an included hand-held air pump. We recommend your dog wear a safety harness you can hold onto, while your dog is exercising on the ball.
