This pet balance disc from FitPAWS can be used for fitness and balance training for dogs or animal rehabilitation and therapy. Its professional-grade heavy-duty material is formulated for dogs, providing superior gripping and resists damage caused by dog nails. This balance trainer has a large training surface and can be used in multiple ways to create a balance training course. The disc has two training surfaces, a ribbed side and a textured surface, to suit different uses. The balance challenge can be easily adjusted by adding more or less air with a needle pump. The pump is not included in the delivery.
