Symptoms of heart failure in dogs

Acute heart failure

1. Sick dogs show high degree of dyspnea, frequent pulse, thin and irregular pulse.
2. The sick dog is unwilling to move, its mouth and conjunctiva are purple, its veins are distended, and it often falls to the ground suddenly and convulses.
3. It is often complicated by pulmonary edema, with bubble-like nasal fluid flowing out from both sides of the nose.

Chronic heart failure

1. The disease develops slowly and can last for months or years.
2. The sick dog is depressed and unwilling to exercise. If he exercises even slightly, he will become tired and have difficulty breathing.
3. The mucous membranes that can be seen in the mouth, conjunctiva, etc. are purple, the veins on the body surface are distended, symmetrical edema often occurs in the extremities, there is no heat and pain, the heart sounds are weakened, and intracardiac murmurs and intracardiac murmurs can often be heard. Arrhythmias.

Causes of heart failure in dogs

1. Temporary overload of the dog’s heart is the most common cause of acute heart failure, such as dogs that have been idle for a long time and suddenly exercise violently. When treating diseases, infusion too fast or too much, especially drugs that strongly stimulate the myocardium (such as calcium preparations), can also cause heart failure in dogs.
2. Heart failure is also often secondary to certain diseases, such as canine parvovirus, toxoplasmosis, myocarditis, various toxic diseases, chronic endocarditis, chronic nephritis, etc.
