Mrs. Leslie Williams, A Manual of Toy Dogs: How to breed…
“ Absolute regularity in feeding is necessary; the meals must be small, yet very nourishing, and the dog should not be allowed to drink immediately after eating. A digestive tonic containing nux vomica is almost invariably useful, but it is not a medicine which can be prescribed at large, for nux vomica is in itself a dangerous drug, and acts much more freely upon some dogs than upon others, making it most unwise to prescribe "so much" for all dogs alike. ”
