_Symptoms_: Heart affections are not particularly common in the dog, except perhaps in Japanese spaniels, and I should think at least a third of these dogs, by the time they are five years old, suffer from some form of heart trouble, principally valvular or dilated heart, which gives rise to difficulty in breathing, especially after exertion, a dry cough, occasionally fainting and loss of condition. Later, as the disease progresses, other complications arise, as enlargement of the liver and dropsy (ascites). _Treatment_: Keep dog as quiet as possible; do not allow any hard exercise or running upstairs. Feed on a meat diet, and occasionally give a course of following mixture:— _Recipe_: Tincture Digitalis, 2 drachms. Tincture Nux Vomica, 1 drachm. Simple Syrup, 1 ounce. Water to 6 ounces. _Doses_: From one teaspoonful to a tablespoonful[1] three times a day, after food. It is important to keep bowels open by occasionally giving aperient medicine. If cough very troublesome, give two or three times a day, made into a pill, from ⅟₅₀th[1] to ⅟₂₀th of a grain of hydrate of heroin, with from half[1] to two grains of hydrate of terpin. =Heat, The=: _See_ ŒSTRUM. =Hemiplegia=: _Symptoms_: Paralysis of one side of body, including limbs. _Treatment_: Unless attack is due to a known cause, as an accident or the result of distemper, commence treatment with a dose of worm medicine, followed by a brisk purge. If no better in a few days, give a course of the following pills:— _Recipe_: Ergotine, 6 to 24 grains.[1] Powdered Nux Vomica, 1 to 4 ” Ex. cip. _q.s._ Mix. Divide into 12 pills—one to be given three times a day after food. When the paralysis is the result of distemper, the same pills may be given, with from one[1] to three grains of reduced iron each time. When the patient is a _small_ dog, the homœopathic preparation of Nux vomica is the best medicine; of this, give five grains of the trituration 3 × three times a day. Cases of hemiplegia are sometimes very slow in mending, and it is a long time before the dog regains the proper use of his legs again; in such instances, electricity should be employed, and a blister to each side of the neck along the course of the spine applied. They should run from just behind the back of the ears to just in front of the shoulder-joint, and be from one to two inches wide, according to the size of the dog. The blisters may be repeated in about a fortnight if necessary. =Hernia=: _Symptoms_: It is a rupture, or protrusion of an organ from its natural position. The most common positions for rupture are the navel; here it is called Umbilical Hernia, the Groin or Inguinal Hernia, and Perineal Hernia, which shows itself by the side, or sometimes both sides, of the anus.
