This is of very rare occurrence, a fact all the more remarkable when we consider how liable the dog is to various spasmodic affections. I have never seen a case of it myself, but Blaine describes it, and it is a recognized canine disease. It is a form of tetanus, and under that head Professor J. Woodroffe Hill describes the symptoms: "When the jaws only are affected, the head is poked out, the jaws are tightly closed, the angles of the mouth are drawn back, the mouth is filled with frothy saliva, and the eyes are fixed in an unnatural and often hideous position."

If you are so unfortunate as to have a dog seized with lock-jaw, place him in quiet place on a good bed where the light is subdued and he will not be liable to be disturbed, and send at once for the best veterinary surgeon you can find. A cure is very doubtful, even with the most skilled treatment; but, as a matter of duty and humanity, try and help your dog through this most dangerous trouble if it is possible. All owners of dogs should keep informed as to the veterinarians in their town or city, as to which one is experienced in canine practice, so that when a case is urgent, you will know what one to call in and just where to find him. Officious ignorance and rough handling would only cause pain without the remotest hope of good results.
