An open-sided tunnel rather than a closed kennel - a dog gets shade and a breeze at the same time, which is what matters on a hot deck. The 420D Oxford canopy is PU-coated against light rain and holds its color under sun. It measures 51 x 46.5 x 42.5 in, big enough for a large breed to lie out flat, and works equally for cats, rabbits or chickens. Ground stakes pin it to grass or decking. Metal poles under 13.5 lbs of fabric. Black, with a gray version also offered. Assembly is required.
