Above-ground kennels aren't little jails. Rather, the kennel is a dog's bedroom and den, a place where a dog feels happy and secure. Kennel's aren't places for running-dogs exercise outdoors. Health-wise, an above-ground kennel keeps a dog away from most vermin and parasites, out of its own mess and off the damp, germ-laden ground. The kennel cage, however, needs just the right floor.
