As a rule, a dog does not show much discomfort after swallowing things like coins, bones, small stones, etc., when they once have reached the stomach, though with young puppies the latter often cause severe colic; but large round stones and corks often cause serious mischief by blocking up the bowels, inducing inflammation, which, if not relieved by operation, soon causes death. Skewers and long hat-pins when swallowed seldom pass beyond the stomach, where they often remain for some considerable time, but sooner or later the point generally pierces the stomach, and peritonitis follows, which quickly terminates fatally; but sometimes the sharp point passes direct from the stomach through the walls of the abdomen and skin, and it may be seen sticking out and can be removed. The dog seems none the worse after a few days, as the wound soon heals. It is often difficult by manipulation to detect things that have been swallowed, for as a rule, as before mentioned, they remain in the stomach for a considerable time before passing into the intestines. I have known coins to remain there for five or six months before being passed; however, with the Röntgen rays coins, keys, jewellery, stones, etc., can always be detected. _Treatment_: Unless the foreign body swallowed is doing the dog visible harm, it is best left alone. Feed on solid food as suet puddings, rice, bread, meat and such like foods, so as to distend the bowels as much as possible and to cause big motions, and the foreign body, in all probability, will pass out safely; _do not give purgative medicines_, which only cause contraction of the bowels and do harm, but if there is pain give from two[1] to ten drops of laudanum in a little water, three or four times a day, or oftener. When the substance swallowed causes real obstruction in the bowel, the laudanum may be given a trial for two or three days, but as a rule an operation becomes necessary, which consists in opening the abdomen, finding where obstruction is, and opening the bowel and removing the offending matter. It is an operation requiring aseptic precaution and some care, and the sewing up the incision made into the bowel wants carefully doing or a stricture may result. =Cold in the Head=: _See_ CATARRH. =Colic=: _Symptoms_: Generally affects puppies from eating rubbish, but may also affect adult dogs, especially after receiving strong medicine as worm medicine. Restlessness, crying and whining, or even howling when pain very severe; abdomen tucked up and muscles feel hard and rigid. The attack may be accompanied by severe vomiting and diarrhœa. _Treatment_: Give immediately, if there is no diarrhœa, a dose castor oil, which should be followed by an enema if it does not operate in about an hour. The enema may consist of half[1] to two teaspoonfuls of glycerine, mixed with one[1] to eight tablespoonfuls of warm water. Also, give following mixture:— _Recipe_:
