In cases of chest founder, or rheumatism in bitches in a weak condition, which occurs after rearing puppies, salicylate of quinine is often the best medicine to give, in doses from half to three grains[1] (made into a pill), three times a day. Dogs suffering from rheumatism should be kept quiet, the affected parts covered over with a thick layer of thermogen wool, and bandaged or rubbed with some liniment, as the following:— _Recipe_: Methylated Chloroform, 4 drachms. Laudanum, 4 drachms. Spirits of Camphor, 1 ounce. Soap Liniment, 1 ounce. Well mix. Apply with friction night and morning. _Diet_: Unless the patient is in poor health, should be light, red meat being avoided; and so should meat extracts and soups to a great extent. When the disease has assumed a chronic form, and settled in some joint, like the knee—a favourite place—strong tincture of iodine should be painted over the front and on each side of the joint every day for three days, or a strong blister applied, and iodide of potassium, in from half to two-grain[1] doses, be given two or three times a day. =Rickets=: _Symptoms_: A disease affecting puppies; if it does not commence before six months of age, it is not likely to occur. In some puppies it commences before they have left the nest, but, as a rule, it does not show itself before the puppy is two months old. The joints, especially the knees and hocks, become enlarged and irregular in shape; the pasterns weak, the puppy walks on the backs of his legs; the arms are bowed, the stifles enlarged and standing out, whilst the hocks turn inwards, giving a “cow-hock” appearance. The bones of the face may be swollen, and there may be a curvature of the spine. The puppy, when suffering from rickets, is always dwarfed in growth, very thin and miserable-looking, with pot belly, and always more or less in pain. The cause of rickets is improper feeding, want of sufficient fresh air, light, and liberty; also worms.
