Over and over again have I been able to convince persons who

After her puppies are about five weeks of age a bitch will begin to vomit the contents of her stomach for the puppies. I have known many breeders of experience argue that but few bitches do so. Over and over again have I been able to convince persons who, having immediate care of the bitch and her litter, deny that the bitch ever vomits to her puppies, that they are wrong. Many bitches never vomit when the attendant is about, and only appear to do so at night; hence the belief that they do not do so at all. It is the natural manner in which the bitch feeds her whelp with partially digested food, after her milk supply ceases to suffice for their requirements. If the bitch is of good constitution and in good health, the puppies flourish remarkably on the diet thus provided, and in such cases my experience leads me to believe that puppies left with their dams do better than when separated from them and, strange to say, bitches who are in the habit of picking up all sorts of apparently undesirable odds and ends do not seem to do their puppies less well under these circumstances than cleaner feeders do.
