Some people have an idea that it is desirable to dose dogs periodically, on the quaint old "spring-medicine " principle, extended over all the year. No greater mistake can be made. A dog should never be given drugs of any kind unless really ill, and this it will never be in the direction indicated, if it is properly fed and regularly exercised. A dog's natural and proper food is meat; but the stimulus of distension must be given to the intestine by adding some bulk of innutritious food to the meat. We cannot give quite enough meat to afford this stimulus constantly, because by doing so we should overload the system. In a state of nature dogs ate the fur and skins of their prey, like other carnivora : now we must give them a certain proportion, but only a small one, of biscuits made of wheat (not of oatmeal or Indian corn meal, which are too indigestible) or of brown bread, to provide bulk without nourishment. They may, if any aperient be absolutely necessary, have a meal of boiled liver, a teaspoonful or two of pure olive oil poured over a little meat, or given from a spoon, or some cod liver oil, which may be voluntarily taken, and is equally efficacious. Milk is very laxative, and sometimes, where there is no biliousness, a small saucerful makes a good aperient.

Always take a dog for his run at the same time of day, wet or fine, and never lose sight of the fact that a well-behaved clean little house-pet may bring upon itself a dangerous attack of constipation by its good manners if its appeal for a walk is ignored.
