Fortunate are the dogs in a kennel during torrid weather, if well provided with shade trees. Nothing would appear to please a dog, especially a terrier, so much on a hot day, as to burrow into the cool earth. If this can be allowed without damage to property by all means let the dogs make their own cool earth nests. If appropriate shade is not afforded naturally it is well to build a lean-to or a square, flat, shed-like structure, as low to the ground as the height of the dogs will allow. They should be able to stand up under it.
