_Diet_: At first liquid, as milk, thickened with equal parts of arrowroot and Benger’s food; after two or three days, raw beef cut up very fine may be given alone or mixed with equal parts well-boiled rice; rice water to drink. In chronic diarrhœa a liquid diet should be given for some time, and in addition to the milk diet previously mentioned, home-made beef-tea (with all fibrine removed) may be given slightly thickened with isinglass, and the following mixture tried:— _Recipe_: Diluted Sulphuric Acid, 2 drachms. Laudanum, 1 drachm. Water to 8 ounces. _Dose_: From a teaspoonful to two tablespoonfuls[1] three times a day. When there is much straining accompanying the diarrhœa, it is a good plan to give an enema consisting of one teaspoonful to two tablespoonfuls[1] of thick-boiled starch, with from three[1] to fifteen drops of laudanum mixed. When the diarrhœa is due to disordered liver, which is generally the case when the motions are white or grey, from one[1] to six grains of grey powder may be given at first instead of castor oil. =Diarrhœa in Puppies=: _Symptoms_: Very often the result of worms, but may be due to indigestion, the result of improper or too much food. Motion liquid and frequent, generally of a yellowish colour. _Treatment_: If worms are suspected give Sherley’s worm tablets for puppies, otherwise first give a small dose of castor oil, and after it has worked off give from two[1] to six grains of carbonate of bismuth every four hours. If the diarrhœa is accompanied by colicky pains give also from two[1] to ten drops of paregoric in a little water three or four times a day. _Diet_: If the patient has been kept on a milk food, discontinue this, and give scraped lean raw meat, a small quantity four times a day; but when a meat diet has been given and the diarrhœa continues, then give milk with Benger’s food or Plasmon. In very obstinate cases from a quarter[1] to one grain of grey powder once or twice a day for three days is often useful. =Discharge from Ear (Canker)=: _Symptoms_: The canal of the ear is red, inflamed, and painful; in slight cases there is often a brownish discharge; in chronic and severe cases the discharge is fœtid and generally purulent, and may be tinged with blood. In these cases the ears are very painful, and the dog cries when he shakes his head. _Treatment_: In very mild cases cleaning the ears daily with a weak solution of Condy’s fluid will often effect a cure; but if the ears are inflamed after cleaning them the canal should be painted twice a day with the following lotion:— _Recipe: Lotion for Ears_: Benzoated Oxide of Zinc Ointment, 2 drachms. Almond Oil, 1 ounce. Well mixed. Each time before dressing the ears they should be carefully wiped out with medicated cotton wool.
