In many cases your druggist or family physician would know what remedy to prescribe for your dog, but would not know how much of the medicine to give a dog.

Let them be guided by the following: A proper sized dose of medicine for the largest breeds of dogs may be given the same as if for a man. We will take the St. Bernard, Great Dane, or Mastiff, as requiring a dose we will call one part; middle sized dogs like a setter or pointer can be given from a half to three-quarters as much as a St. Bernard, while a dog like a fox terrier, a third; a dog the size of a pug, a quarter; and smaller toy dogs, from one-eighth to a twelfth part.

In regard to age: the matured dog, one part; a year old, three-quarters; six to nine months, half; and at four to six weeks, one-eighth. This is Dalziel's idea, and he is the first one to furnish a guide that I know of. I have had doctors bring their dogs to me to treat, and tell me that they really did not know how much to give the dog of the remedy that they knew was required in the case.
