Red Paddle Co makes some of the best inflatable boards. The quality is great (even better in the 2016 models), and they are really fun to paddle. The Surfer 10' wasn't difficult to pump up. The last few psi might require body weight to get the pump handle down, but it was very doable for this mid-fifties female. The board is lightweight and easy to cartop. The material is extremely tough and offers great grip for dogs and humans.
Weight, durability, very dog friendly. Easy to maneuver. Stable. Easy enough to inflate, and can be left inflated with no problems. Don't need to worry about rocks or dropping the board, as it's nearly indestructible.
As a 10' board, it doesn't track or go as fast as a longer, narrower board. Bought new, Red Boards are a bit expensive.
