The Pup Plank was invented to make it easier for water-loving dogs to get in and out of the water. Whether it be on the boat, off the dock, or in the pool - attach the Pup Plank and let your dog effortlessly enjoy the water. Gone are the days of you, the owner, having to struggle lifting your dog out of the water. The Pup Planks integrated weighted mesh sinks below water-level to create an effortless entry-point for swimming pets. The frame is designed with premium-grade PVC and our state-of-the-art drop-stitch technology, so the Pup Plank feels rigid when inflated, and is incredibly light and compact when folded up - making it the perfect item for your boat. 48 Inch length x 32 Inch width x 5 Inch thickness when unfolded.
