_Wounds_ the result of the bite of a dog suffering from rabies should be immediately and freely cauterised with fuming nitric acid or a saturated solution of chromic acid, but unless the dog is a very valuable one, he should be destroyed, as it is running a great risk to keep a dog that has been bitten by one suffering from this disease. Besides cauterising the wound, the bitten dog should be very securely isolated for three months so that he cannot possibly come in contact with either man or other animal. APPENDIX =Back, Injuries to=: May be the result of a blow, or due to a sprain when jumping. It often occurs as the result of a dog being run over across the back. _Symptoms_: Pain on pressure to the part; in bad cases the dog walks with difficulty, and with back arched and tail down. In slight cases, though there may be pain on pressure, the dog walks, when first starting out, fairly well, and seems bright; but after going a short distance he soon lags behind, loses his spirits, and droops his tail. In other instances of a slight nature, the dog is able to walk easily but is unable to jump, and, if he attempts to, he cries out. _Treatment_: It consists principally in giving the dog rest. Sometimes several weeks’ quiet are necessary, as well as rubbing the back with some anodyne liniment, as the following:— _Recipe: The Liniment_: Chloroform (meth.), ½ ounce. Tincture Hyoscyamus, ½ ounce. Spirits of Camphor, 1 ounce. Soap Liniment, 1 ounce. Mix. Apply with gentle friction once or twice a day to the painful parts. A dose of aperient medicine does good, and whilst the dog is at rest a light diet should be given. =Feeding=: Dogs require concentrated food, and to keep a dog in the best condition, meat should form half his diet. Taking first the toy breeds. When puppies are weaned, it must be remembered that the mother’s milk is far stronger than cows’ milk, and when possible, goats’ milk should be given; cows’ milk thickened with Plasmon is a good substitute. The mother should be allowed to feed her puppies during the night in the initial stages of weaning.
