_Treatment_: Encourage the sickness by giving a dose of sulphate of zinc or ipecacuanha wine. Stimulate the action of the bowels with free doses of Epsom salts; give milk to drink, with white of egg added. If the pain is very severe, an enema of laudanum and ether will soothe. When there is great prostration, Brand’s essence may be given—a teaspoonful or so every hour. [Illustration: A dog in a bag which is very useful when it is necessary to keep his tongue and teeth away from a wound or when some poisonous dressing has been applied] =Prepuce Orifice, Too Small=: Puppies are occasionally born with the opening in the prepuce too small, so that the penis is unable to be protruded. [Illustration: A wide leather collar to prevent a dog from turning his head round] _Treatment_: The difficulty is removed by a small operation—that is, by increasing the opening by making a small incision, and then sewing the skin to the mucous membrane. It is best not to do this operation until the puppy is three or four months old, and care must be taken during the healing that the wound is not licked. This is best done by making the puppy wear a wide collar, or keeping him in a sack for a few days, with the head only protruding as depicted in the illustration. =Prepuce Orifice, Too Large=: Occasionally puppies are born with the opening in the prepuce so large that the penis is always protruding. _Treatment_: The opening may be partly closed by scarifying the edges of the skin, and then sewing it up. Care must be taken that the dog does not lick the part during the healing. =Prostate Gland, Enlargement of=: _Symptoms_: Difficulty in passing water—straining; also difficulty in passing a motion—constipation. When very large, they may be felt by manipulation of back part of abdomen (the pubic region) just in front of the thighs. _Treatment_: If dog unable to urinate properly, the water must be drawn off with a small-sized catheter. The bowels must be kept in a semi-relaxed condition by mixing with the food, twice a day, from half to a dessertspoonful[1] of salad oil. Also, give twice a day, from a quarter[1] to two grains of iodide of potassium in a little water. The extract of prostate gland may be tried—dose, from half a grain to two grains.[1] An operation for enlarged prostate gland in the dog is not satisfactory, but castrating a dog suffering from this disease often has a good effect. =Prostatitis (Inflammation of Prostate Gland)=: _Symptoms_: Increased frequency of passing water, and straining after emptying bladder, when a few drops of blood are often passed. Big dogs are more subject to the disease than small ones. _Treatment_: Do not take the dog for long walks; feed principally on milk, with biscuits, bread, toast, rice, etc. Fish may also be given, but avoid meat. Give aperient medicine, castor oil is the best, also tonic medicine, as the following pills:— _Recipe_:
