_Symptoms_: Generally commences suddenly with an attack of shivering and a rise of temperature, there being often three or four degrees of fever accompanied by a rapid pulse. There is pain in the back, vomiting, scanty and high-coloured urine, or blood may be mixed with the water. In some acute cases it is quite suppressed, and the dog then suffers from uræmic poisoning. It may arise from a severe chill, but oftener from a stone in the kidneys. _Treatment_: Give milk and Vichy water in equal parts to drink, also water to drink, to which has been added a teaspoonful of cream of tartar to every pint. Administer a dose of Epsom salts, from one scruple[1] to one ounce, dissolved in warm water, but given cold. If vomiting persistent, give from half[1] to two drops of diluted hydrocyanic acid in a teaspoonful of water, and ice to lick. After the acute stage has passed, give from one[1] to five grains of ammoniated citrate of iron, three times a day in water. =Nettlerash=: _Symptoms_: Generally arises suddenly, and often the result of a chill, as, for instance, a dog plunging into cold water when hot after exercise. When once a dog has had an attack, he is liable to a recurrence, and then indigestion will often induce it. The skin becomes suddenly nodulated or swollen in patches, the hair standing on end. The ears may be affected and become half an inch thick; the head is often attacked, and the dog is temporarily blind because the eyelids are swollen. Sometimes one or more legs are the seat of the trouble, and become three or four times their normal size; in other cases, large patches appear about the body. As a rule, it passes away almost as quickly as it comes. _Treatment_: Keep dog quiet and warm whilst the attack is on, and give from half to two drops[1] of liquor arsenicalis (P. B.) in a little water every two or three hours. Also give a good dose of aperient medicine. For a few days after a dog has had nettlerash, he should be kept on a light milk diet, and given a course of arsenic, as from one to eight drops[1] of liquor arsenicalis in water, three times a day after food. =Neuralgia=: _Symptoms_: Dogs are affected with a form of neuralgia that attacks the muscles and nerves of the neck and shoulders. The pain, which is very acute, comes on quite suddenly, and the dog cries with it. The head is drawn into the body, as it were. The muscles are swollen, and very tense. There is a difficulty in walking; and when it is attempted, it is done very slowly and stiffly. The attack may last a couple of hours, sometimes longer, and then slowly passes off, and the patient may appear quite well; when all at once it may come on again as bad as before, and so keeps on for days, and sometimes weeks, unless some suitable treatment is adopted.
