These destroy, I believe, quite as many puppies as distemper, and are a fertile source of disease. Some authorities believe that the ova remain in kennels from year to year attached either to the walls or benches. Now, besides the worms usually met with in the intestines, there are others, including the large kidney worm, and the hydatid found in the dog's brain. We will, therefore, briefly enumerate the respective kinds.

The maw-worm is considerably larger than its fellow, which is found in the human subject, it being about an inch long and of a white milky colour, with one end abruptly terminating, and the other end pointed. They exist in large numbers, and occupy the great intestines chiefly. They do not injure the health to any serious extent unless they exist in very great numbers. They are male and female, and propagated by ova.

The round worm measures from four to seven inches long, is round, firm, and of a pink colour. Both extremities are exactly alike; they often accumulate or collect together, forming a solid mass something like an egg. They are also developed from ova.

The tape-worm is, generally speaking, the most unpleasant of the tribe; it attains the length of several feet, and is divided into separate sections, each section being capable of producing oca to an almost indefinite extent; and as these are passed from the body with the feces, they are readily communicated from one dog to another. The injury inflicted by these worms is certainly great, because they not only abstract the nourishment from the dog, but they continually keep up a systematic irritation which is very annoying to the patient, therefore it is of the utmost importance that they should be expelled as soon as possible.

The kidney-worm claims the kidneys as its habitation. It is of a dark blood-colour, probably owing to the nature of its food, which is derived from the vessels of the kidneys. In the human subject this worm has been known to be the length of three feet, and half an inch in diameter.

The presence of worms in the dog, and their symptoms, should be intelligently looked for and noted carefully, if the animal's health is considered at all

The evidences are as follows - unhealthy appearance of the coat, hair appears as if it was dead and standing erect, appetite ravenous, condition generally low, feces passed frequently and in small quantities, with small quantities of mucus each time. The spirits of the dog seem depressed, nose hot and dry, breath offensive. When these symptoms are observed, the feces ought to be watched, and shortly you will discover the sort of worm that is producing the mischief.

Treatment

For maw-worm, areca nut, stinking hellebore, calomel, wormwood, cowhage, etc.

For tape-worm, spirit of turpentine is the most deadly, or the oil of male fern. Turpentine ought always to be given with oil, as the oil protects it, or prevents it from injuring the mucous membranes or the kidneys. Any of these remedies ought to be followed up next day with a dose of castor-oil administered to the patient fasting.
