Just to cause an action of the bowels in cases of constipation, only a small enema is required as, say for a little dog like a griffon, half a teaspoonful of glycerine mixed with a couple of tablespoonfuls of warm water. For dogs the size of fox terriers double the quantity may be given. For collies, etc., four times the quantity; and for dogs like a St Bernard half as much again of both the glycerine and water. Instead of glycerine, soapy water may be used. In cases of real obstruction of the bowels, give double the quantities as advised in cases of simple constipation, and the enema should be repeated in these cases three or four times a day. Very often in cases of obstruction of the bowels, it is a very good plan to give an occasional enema consisting of warm oil, or even from five grains to half a drachm[1] of ox gall dissolved in hot water. For little dogs a glass ear-syringe may be used which can be bought to hold half an ounce or an ounce. For bigger dogs one of Higson’s enema syringes are the best. The bone point, before inserting into the bowel, should be well vaselined, and then it can be safely passed into the rectum its whole length, which is about two inches. Care should be taken when giving enema not to pump a lot of air into the bowel. Another way of relieving constipation, when one wishes to avoid giving medicine by the mouth, is to pass a suppository made of glycerine and gelatine into the rectum. These have their advantage over enema, as they do not wet the dog when the bowels operate, which is important in cases of paralysis when dogs cannot stand whilst passing a motion. Failing a glycerine suppository, a piece of yellow soap cut the shape of one answers the purpose. =Enteritis (Inflammation of the Bowels)=: _Symptoms_: Attack often commences with vomiting. There is generally slight rise of temperature and a quickened pulse, pain on pressure of abdomen; there may be constipation or diarrhœa, but in any case mucus is generally passed with the motion. The dog seems ill, lies about, and is disinclined to move. There is loss of appetite, and the thirst is generally excessive.
