Fleas.
The bane of a dog’s existence is fleas. They are especially troublesome to puppies, worrying them till they become fretful, causing them to irritate the skin and tear their coats through scratching, seeking relief from itching. In addition, where fleas are particularly numerous on a dog they will often so affect it that its appetite is impaired and its digestive organs affected by worriment.
Carbolic soaps will kill these pests, also destroy the hair if constantly used; therefore the greatest permanent relief is found in using a powder. The best results can be attained by taking the dog into the yard or street, dusting it thoroughly with P. D. Q. Compound Powder, rubbing it well into the skin, when both fleas and nits will cease to exist. It is not injurious either to the dog or its hair, and if used on furniture or carpets will prove equally efficacious.
