The dog's body is long, lean, and very muscular, a fat dog being usually pampered and old. The coat is of hair and is not of fine fur like that of the cat. It is of inter- est to note that the Newfoundland dog has an inner coat of fine hair comparable to that of the mink or muskrat. When a dog is running, his body is extended to its fullest length; in fact, it seems to "lie flat," the outstretched legs height- ening the effect of extreme muscular effort of forward movement. A dog is master of several gaits; he can run, walk, trot, bound and crawl. The iris of the dog's eye is usually of a beautiful brown, al- though this varies with breeds; in puppies, the iris is usually blue. The pupil is round like our own; and dogs cannot see well in the dark like the cat, but in dayhght they have keen sight. The nose is so much more efficient than the eyes, that it is on the sense of smell the dog depends for fol- lowing his prey and for recog- nizing friend and foe. The damp, soft skin that covers the nose, has in its dampness the conditions for carrying the scent to the wide nostrils; these are situated at the most forward part of the face, and thus may be lifted in any direction to receive the mar- velous impressions, so com- pletely beyond our compre- hension. Think of being able to scent the track of a fox made several hours previously. Not only to scent it, but to follow by scent for many miles without ever having a glimpse of the fleeing foe! In fact, while running, the dog's attention seems to be focused entirely upon the sense of smell, for I have seen hounds pass within a few rods to the windward of the fox they were chasing, without observing him at all. When the nose of any of the moist-nosed beasts, such as cattle and dogs, becomes dry it is a sign of illness. A light fall of damp snow gives the dog the b
