The FitPAWS® Balance Disc can be used for weight-bearing activities and balance training for sporting and working dogs or for animal rehabilitation and therapy. The professional-grade, heavy-duty PVC material is formulated for use with dogs, provides superior gripping and resists damage caused by dog nails. The FitPAWS Balance Disc has a 14" training surface and may be used in multiples to create a balance training course. The FitPAWS Giant Balance Disc has a 22" training surface, perfect for medium/large breeds. Both discs have two training surfaces, a flat/smooth side and a textured surface. The balance challenge can be easily adjusted by removing or adding air with a needle pump for the 14" balance disc or an air pump for the Giant balance disc.
