This book of the dog and his friends does for the canine member of the household what Helen M. Winslow's book, "Concerning Cats," did for the feline. No one who cares for dogs--and that class includes nearly all who do not care for cats, and some who do--will admit that the subject of Mrs. Bolton's book is a less felicitous choice than that of its predecessor; while the author's well-known ability as a writer and lecturer, as well as her sympathy with her subject, are a sufficient guarantee of a happy treatment.
