There are two kinds of lice which infest dogs, and both of them are quite similar to those infesting man. One, the Haematopinus piliferus, is generally found about the throat and back of the ears, but may extend over all parts of the body. The female is two mm. long, in color a yellowish white, the head being a little darker than the body. The male is 1.15 mm. long. The head is short and as wide as it is long. It is salient and is exactly applied to the thorax. The third and fourth articles of the antennae are alike. The female is about 2 mm. in length. The abdomen is a long oval in shape and well developed. It is made up of nine round segments, the first seven having two rows of short bristles. The other louse (Trichodectes latus) is a bright yellow, with dark spots, with blackish brown bands on the head. The female in length is 1.5 mm., the male 1.4 mm. The head is wider than it is long. The antennae are hairy and different in both sexes, the first article in the male being much thicker than the other. The abdomen is broad and more rounded in the female than in the male and has lateral but no median spots.

Lice live in all parts of the body - the roots of the ears, around the eyes and all about the head and face, as well as along the top of the back. They set up an irritation that causes the dog to scratch and worry continually, and if the skin be closely examined streaks and dots of blood will indicate the feeding places of these pests, which are easily discerned creeping about. The rapidity with which lice multiply is marvelous. Independent of the destructive influences which restrain their multiplying, it is estimated that the descendants in the third generation of one female louse will number 125,000.

The most effectual and the safest remedy for the destruction of lice is a lime and sulphur lotion. The skin should be thoroughly saturated with it for ten or fifteen minutes, and at the end of this time the dog should be given a bath in lukewarm water, a standard dog soap being used. He should then be brushed and combed until thoroughly dried. Covering the dog with a mixture of cotton seed oil and crude coal oil in equal parts and then washing the dog at the end of a half hour with warm water and dog soap will kill either fleas or lice.

Eberhart's Skin Remedy will kill lice. It should be thoroughly rubbed in, not missing a spot on the dog. After it has been on half an hour, then the dog can be washed and dried; this bath only given to remove the grease, if it is a house pet. . If in warm weather, and dog can be kept out in the yard, the bath is not necessary. The application must be repeated at least once more, in twenty-four hours, to kill the nits or the young ones that are born every twenty-four hours. My dog soap will kill lice, if you apply it thoroughly, and allow it to remain on (.and repeat once or twice more.

For pet or house dogs the insect powders generally made from the powdered flowers of pyrethrum roseum will be found most convenient. Unfortunately their expense precludes their general use in kennels. The powder must be well rubbed into the roots of the hair or blown in with a small bellows, made for that purpose, that is of assistance in spreading it well around the roots of the hair. After allowing it to remain on some time - fifteen minutes to one hour - it can be dusted out over a sheet of paper, which can then be rolled up and burned.
