Recipe:

Castor Oil,}Equal parts.
Syrup of Buckthorn,}
Salad Oil,}
Well mixed.

Doses: From half a teaspoonful[1] to two tablespoonfuls, fasting, in the morning.

For little dogs suffering from constipation, salad oil mixed daily with the food answers well. Give from a half[1] to a teaspoonful once or twice a day.

Some dogs refuse to take their food with oil in it. In these cases, fluid magnesia is a nice mild laxative; and one,[1] two, or three teaspoonfuls may be given with a little milk at breakfast-time. A little gingerbread cake, given at night, keeps a small dog’s bowels very regular; besides, it is appreciated.
