Nearly all dogs that are deprived of their liberty, either wholly or in part, are subject to what is known as sour stomach, generally caused by overfeeding, in parred digestion, or the presence of food that ferments before digestion takes place. A sour breath, often accompanied with vomiting or indications of it, are symptoms that generally accompany this trouble. A simple and very efficacious corrective of this is to be found in common cooking soda, or bicarbonate of soda. The dose for a fifty-pound dog is a level teaspoonful dissolved in a small quantity of water or milk, to be repeated two or three times, each half hour, if thought to be necessary. Usually, however, one dose will be sufficient. For smaller animals the dose should be proportionately reduced, and one-half the quantity will be sufficient for an animal the size of a fox terrier. This simple remedy I have found to be invaluable, and for many years I have freely used it, both for myself and family as well as for my dogs.

My knowledge of the efficacy of this remedy was - obtained more than forty years' ago in the wilds of Iowa, while on a shooting trip. One of my dogs was attacked with a spell of retching that continued for some time, and a lady where I was staying suggested the remedy, and it was at once administered, with most beneficial results. Although I have since that time sorted the contents of my medicine chest many times, and discarded a very large proportion of them, cooking soda still remains one of the most valued articles it contains.
