_Symptoms_: This condition generally follows some severe illness affecting the kidneys or bladder when the suppression of the secretion of urine has occurred. Anything that stops the flow of water from the bladder, as stone or stricture, may cause it; it also occurs in bad cases of stone in the kidney. In these cases the dog is very ill, there is an entire loss of appetite and often severe vomiting; a heavy, sleepy condition soon comes on, and the temperature is very high. The white of the eyes are greatly congested, and any urine passed is of dark colour and may be mixed with blood. Sometimes there are convulsions, but the dog soon sinks into a comatose state. As a rule these cases terminate fatally. _Treatment_: It is often difficult to give medicine by the mouth in these cases as the vomiting is generally so severe and frequent, but the dog is able, as a rule, to drink milk and Vichy water in equal parts. If possible, give a purgative, Epsom salts being about the best. The dose is from fifteen grains to one ounce,[1] given in water, or with milk and Vichy water if the dog can be persuaded to take it. Small doses of urotropine stimulates the action of the kidneys, from one[1] to eight grains in a cachet may be given every four or six hours. Hot linseed-meal poultices to loins relieve the kidney congestion. As to diet, milk and Vichy water are quite sufficient to sustain the dog for two or three days, when, if patient is better, fish may be given, but when this cannot be digested, peptonised milk, from one to six[1] tablespoonfuls, may be given every two hours. =Urethritis=: _Symptoms_: Pain when passing water, or when handled; mattery discharge often tinged with blood from passage. The penis is swollen and red from the inflammation. This condition is generally caused by the passage of gravel, and it may also be the result of frequently passing a catheter. _Treatment_: Hot poppy-head fomentations do good. For medicine give from three[1] to twenty grains of hyposulphite of soda in water three times a day. If there is much pain, from two[1] to ten drops of tincture of henbane may be given with each dose of the above. Feed principally on a milk diet; some boiled fresh fish may be given, but meat must be avoided. =Urine (Incontinence)=: _See_ INCONTINENCE OF URINE. =Urine (Sediment in)=: _Symptoms_: The urine may be passed white and cloudy, or clear, but of a high colour, and when cold there is a thick, yellowish-white deposit. _Treatment_: When accompanied by some illness with a high fever, no special treatment is necessary, as the condition will pass away as the health improves, but when the symptoms described are present and the dog seems otherwise apparently well, give a course of hyposulphite of soda, from three to twenty[1] grains two or three times a day in water or a little milk. A dog will generally take this medicine himself when mixed with milk.
