_Treatment_: When the skin only is scorched, apply lime water and linseed oil. One part of the former, mixed with two parts of the latter, should be dabbed on two or three times a day. In severe burns the part may be smeared over with boracic ointment, and when the blister has broken the same ointment should be applied on lint, which must be kept in its place with a bandage or coat. Repeat dressing two or three times a day. =Calculi (Stones in the Kidney)=: _Symptoms_: Blood, and also in many cases pus, is passed with the urine. The dog at times seems very ill, the temperature may go up to 103 or 104. Pain on pressure over the loins, sickness, loss of condition, and great wasting. In severe cases there is collapse, and death follows the result of uræmia poisoning. _Treatment_: Open the bowels freely. Apply hot fomentations or poultices to the loins, and give following medicine:— _Recipe_: Bicarbonate of Potash, 1 drachm. Boro-citrate of Magnesia, 1 ounce. Mix. Give from sufficient to cover a sixpence to a teaspoonful,[1] two or three times a day, mixed with food or milk. _Diet_: Give plenty of milk mixed with equal parts Vichy water. Also Benger’s food with milk, tripe, and fresh boiled fish, with well-cooked rice. Avoid red meat. =Calculi in Bladder=: _Symptoms_: In the dog the stones are generally small, varying in size from a millet seed to a pea, though occasionally one does find a large one. In bitches the stone is generally not discovered until it has become a good size, and set up irritation of the bladder. In the dog, when the stones are small they, as a rule, do not seem to do any harm or cause inconvenience until one or more escape from the bladder, pass into the urinary passage or urethra, and become lodged in the canal just behind the bone in the penis where the passage is smallest. If the stone is quite round—which, fortunately, is not always the case—it acts like a cork in a bottle, and the dog is unable to pass any water. He stands or stoops like a bitch, and keeps straining; but nothing comes away, except, perhaps, a single drop occasionally of blood-stained urine. If the stone happens to be not quite round, then he is able to pass a small quantity of highly-coloured water by great effort. To ascertain for certain if these symptoms are the result of gravel or stone, a small sound or catheter should be passed; and if there is any blockage in the passage it is easily ascertained, for in that case it will be impossible to pass the instrument for more than a few inches instead of from 6 to 24 inches, according to the size of the dog; and besides, the hard piece of gravel or small stone will be felt. In some cases when the stone is not quite round the instrument will pass to the side of it, and then one can easily feel the grating of the stone against the instrument as it passes, more especially as it is withdrawn.
