All dog tents should be strong and rugged. They have to withstand scratches but it is difficult to find one in the market that can stand up to constant chewing. It may be good to cut a dog's nails with clippers or better yet, a dog nail grinder, to prevent tearing by accident.
Almost all dog tents can be folded or taken apart to make it easier to transport. These come with the exception of canopy beds that are used for short trips and gardening but not for backpacking. If hiking with a dog tent, it is important to consider its weight and size when folded. In case the tent does not come with a built-in bed, there should be a separate mat, which also contributes to the overall weight.
