_Symptoms_: This disease may affect almost any part of dog, and also dogs of all ages, though old ones are no doubt more liable to it. When it attacks the muscles of the neck, it often assumes a spasmodic form, and the pain is sometimes very acute; the dog is unable to move his head in any direction, the muscles, from contraction, appear swollen, are very tender to the touch, and the dog cries with the pain. The attack generally lasts some hours, then it gradually subsides, and the dog seems all right for a while, when it may come on again. Then, rheumatism often affects the shoulders, and when it does, it is called “Chest Founder”. The parts are painful and stiff, and the dog walks with difficulty, dragging the fore feet along the ground. Bitches, when in low condition after rearing a litter of puppies, often suffer from this form. Then the loins, again, are the frequent seat of this disease, and when it affects this part it is called lumbago. The dog walks with arched back, and very stiffly—and as when the other parts of the body are affected, there is a good deal of pain. As the result of lumbago, a dog often loses the use of the hind legs for a time, and in fact becomes quite paralysed. The disease is not confined only to these parts mentioned, as the joints of the fore and hind legs are liable, and a very characteristic symptom of rheumatism is its changing about quickly from one part to another, which is unlike any other disease. For instance, one day the dog may be going dead lame in one of the back legs, the next day the other hind leg may be affected, and the one that was bad the previous day quite free of pain, or the disease may leave the hind parts and go to one of the fore limbs. But this is not always the case, as the disease may settle in a joint, or some muscles, say of the loins, and remain stationary for a long time. _Treatment_: This is practically the same at first, at any rate, whatever part may be affected. The thing is to try and get the disease out of the system. It is always a good plan to commence with a good purge; after this has worked off, give a course of salicylate of soda, from two to fifteen grains[1] three times a day, either in tabloid form, put up in cachets, or even dissolved in a little water. If this medicine does not give relief in twenty-four hours, try aspirin or salicine, the doses are the same. When the muscles of the neck are affected, the pain is often very acute, as mentioned before. In such cases it is frequently necessary to administer some sedative medicine, and for this I find there is nothing better than giving, subcutaneously, from the twentieth to the eighth of a grain[1] of acetate of morphia, with from ⅟₃₀₀th to ⅟₁₅₀th of a grain[1] of sulphate of atropine, the two to be dissolved in from five[1] to ten minims of water. The dose should be repeated night and morning for a few days. At first these injections may cause vomiting, but this soon ceases.
