On the next morning he was found dead. All the viscera were sound except the bladder, which was ruptured; the abdomen contained two quarts of bloody fluid. The mucous membrane of the bladder appeared to be in the highest state of inflammation. It was almost black with extravasated blood. On the neck of the bladder was an enlargement of the size of a goose's egg, and almost filling the cavity of the pelvis. On cutting into it, more than two ounces of pus escaped. On June 29, 1833, a poodle was brought to me. He had not been observed to pass any urine for two days. He made frequent attempts to void it, and cried dreadfully. The bladder could be felt distended in the abdomen. I put him into a warm bath, and took from him a pound of blood. He seemed to be a little relieved. I did not leave him until after midnight, but was soon roused by his loud screams, and the dog was also retching violently. The cries and retching gradually abated, and he died. The bladder had burst, and the parietes were in a dreadful state of inflammation. A dog had laboured under incontinence of urine more than two months. The water was continually dropping from him. The servant told me that, three months before, he had been shut into a room two days, and, being a cleanly animal, would not stale until he was liberated. Soon after that the incontinence of urine was observed. I gave the usual tonic balls, with a small portion of opium, night and morning, and ordered cold water to be frequently dashed on the perinæum. A month afterwards he was quite well. Comparatively speaking, 'profuse staling' is not a common disease, except when it is the consequence of bad food, or strong diuretics, or actual inflammation. The cause and the result of the treatment are often obscure. Bleeding, purging, and counter irritation, would be indicated to a certain extent, but the lowering system must not be carried too far. The medicine would probably be catechu, uva ursi, and opium.
