_Symptoms_: Dogs, especially big ones, occasionally suffer from a very bad form of “wind or gas in the stomach”, which is a very serious illness, often terminating fatally in a few hours, due to rupture of the stomach, the result of over-distension. The gas is formed by a germ generally present in all dogs’ stomachs and bowels, and called “Bacillus Communis Colli”, and sometimes without any apparent reason or cause they take on an active form with the result as above mentioned. The attack usually comes on shortly after eating. The dog becomes restless and breathes quickly, the abdomen is full and tense, the dog has an anxious look, the eyes are congested, and the pulse very quick and small. The distension continues to increase, the abdomen often assuming an enormous size and hard as a drum, and the pain is acute. Unless relief is quickly obtained the dog suddenly collapses, the stomach having ruptured and the contents escaped into the abdominal cavity. Acute peritonitis sets in, and the dog dies in a few hours as much from shock as the disease. _Treatment_: It is generally unsatisfactory, as the symptoms are so acute that there is little time to do anything before the dog becomes collapsed; however, now and then benefit is derived by giving a strong dose of antiseptic medicine, as cyllin, from two to six[1] minims, which can be obtained in gelatine capsules; the dose may be repeated in a couple of hours. If cyllin cannot be obtained give from two to fifteen[1] grains of Naphthol Beta in a cachet; this also may be repeated in a couple of hours. Failing this medicine, then give from five to forty[1] drops of Pearson’s Antiseptic Fluid in a gelatine capsule or cachet, and this too may be repeated in a couple of hours if necessary. Sometimes benefit is derived by washing the stomach out with a solution of the fluid just mentioned diluted two hundred times with tepid water, using from one ounce to half a pint of the solution.[1] This must be done with a stomach pump. When everything else fails, it is advisable to submit the dog to an operation, which consists of opening the abdomen, and then puncturing the stomach to allow the gas to escape, but care must be taken not to let any of the contents of the stomach escape into the abdominal cavity. The wound made in the stomach must be afterwards carefully closed by Lembert’s sutures. =Womb (Inflammation of)=: _See_ UTERUS (INFLAMMATION OF). =Worms in the Heart= (_Filaria Immitis_):
