A good watch dog is of inestimable value to the farmer; and as very little is at present understood of the nature and treatment of their maladies, we have thought that a few general directions would be acceptable, not only to the farmer, but to every man who loves a dog. We have paid considerable attention to the treatment of disease in this class of animals, and have generally found that must of their maladies will yield very readily to our sanative agents. Most of the remedies recommended by _allopathic_ writers for dogs, like those recommended for horses and cattle, would at any time destroy the animal; consequently, if it ever recovers, it does so in spite of the violence done to the constitution. We hope to rescue the dog, as well as other classes of domestic animals, from a cruel system of medication; for this we labor, and to this work our life is devoted. We ask the reader to take into consideration the destructive nature of the articles used on these faithful animals. Some of them are the most destructive poisons that can be found in the whole world. For example, several authors recommend, in the treatment of disease in the canine race, the following:-- _Tartar emetic_, a very few grains of which will kill a man--yet recommended for dogs. _Calomel_, a very fashionable remedy, used for producing ulcerated gums and for rotting the teeth of thousands of the human family, as the dentists can testify. Not fit for a dog, yet prescribed by most dog fanciers. _Lunar caustic_, recommended by Mr. Lawson for fits; to be given internally with cobwebs!! Our opinion is, that it would be likely to give any four-footed creature "_fits_" that took it.
