I have never seen more than one in a case, and the dog seems comfortable directly it has got rid of its guest.
Nasal Polypus:
Symptoms: A growth with a narrow neck which forms in the nasal passage causing irritation, sneezing and snorting, a purulent discharge which may sometimes be tinged with blood.
Treatment: Consists in removing the growth by ligature if it can be got at, or by an ecraseur or a snare; but it is a surgical case, and a veterinary surgeon should be consulted.
Necrosis (Diseased Bone):
Symptoms: Generally the result of some injury. The parts are swollen, inflamed, and very painful, and generally an abscess forms, which, if not lanced, bursts, discharging a thick, creamy and often offensive-smelling pus. The bone, which is generally dead, lies exposed at the bottom of the wound, which does not heal permanently until the dead bone comes away.
Treatment: At first, hot linseed-meal poultices dusted over with powdered charcoal are to be applied, and continued for some days after the abscess is open. Then lint saturated with carbolic oil, one in forty, is to be placed over the wound, and kept in place with a bandage. As a rule, after some time the dead bone exfoliates and comes away of itself, and the wound then soon heals, but in many cases, an operation is necessary to remove the dead bone.
Nephritis (Inflammation of the Kidneys):
Symptoms: Generally commences suddenly with an attack of shivering and a rise of temperature, there being often three or four degrees of fever accompanied by a rapid pulse. There is pain in the back, vomiting, scanty and high-coloured urine, or blood may be mixed with the water. In some acute cases it is quite suppressed, and the dog then suffers from uræmic poisoning. It may arise from a severe chill, but oftener from a stone in the kidneys.
