It's highly unlikely for a dog to puncture an inflatable paddle board. These boards are typically made from multiple layers of durable materials. To minimize risk, ensure your dog's nails are trimmed, and choose a board made from strong materials. The combined weight of the user and the dog should be within the board's capacity. A dogs nails will NOT pop a Hydrus board. Their nails or even teeth won't be able to break the "skin". Just be mindful of the traction pad.
