Dog-biscuit is a hard and well-baked mass of coarse, yet clean and wholesome flour, of an inferior kind to that known as sailors' biscuit; and this latter substance, indeed, would be the best substitute for the former with which we are acquainted. A bag of dog-biscuit of five shillings' value, will be an ample supply for a yard-dog during the year: it should be soaked in water, or " pot liquor," for an hour or two ; and if no meat be at hand, a little dripping or lard may be added to it while softening, which will make a relishing meal at a trifling cost. We have for many years known the utility of the plan thus advocated, and we earnestly recommend all who value the safety of the community and their own (to say nothing of the happiness of the canine race), to make trial of the rational and feasible plan which we have detailed."

More than 70 years ago, in a little shop in London an electrician named James Spratt conducted experiments which led to the production of Spratt's Patent—a scientifically blended dog food. It was the first attempt to lift the dog out of the class of scavenger which he had occupied from caveman times. The market was untouched, and in those early days, Spratt's Patent secured a bull-dog grip on it that it has never relinquished, despite the fact that in the past seventy years many competitors have tried to wrest the leadership from them.
