Dimensions: 2L x 18.25W x 15H in. Stabilize joint. Foam construction. Use for balance and motor-skill training. Increase difficulty by using multiple pads. Help your dog build strength and prevent injuries with the Ball Dynamics FitPAWS Canine Balance Pad. Each Balance Pad is crafted of dense foam that slowly compresses under your dog's weight. The slow, gradual change in elevation of your dog's paws creates a balance challenge that activates the core muscles. Purchase two and stack them for more advanced work. For larger dogs, you can place two balance pads side by side to create an appropriate level of challenge.
