Heart failure in dogs is not an independent disease, but refers to the severe stage of heart disease caused by various causes.
1. Causes of heart failure in dogs:
1. The dog's heart is overloaded temporarily, which is the most common cause of acute heart failure. For example, dogs who are leisurely for a long time, suddenly and vigorously exercise; when treating diseases, the infusion speed is too fast or too much, especially drugs that are highly irritating to the myocardium (such as calcium preparations).
2. Heart failure is often secondary to certain diseases, such as canine parvovirus disease, toxoplasmosis, myocarditis, various toxic diseases, chronic endocarditis, chronic nephritis, etc.
2. Clinical symptoms of heart failure in dogs:
It is mainly based on the cause of the disease, systemic blood circulation disorders, and symptoms worsen after slight exercise, especially changes in heart sound and pulse. A comprehensive analysis can be confirmed.
a), Acute heart failure:
1. The sick dog shows high dyspnea, frequent pulse, thin and weak but uneven.
2. The sick dog is unwilling to move, and the conjunctiva of the oral cavity becomes purple, the veins are vented angrily, and often falls to the ground and convulse and twitch.
3. There are many pulmonary edema, and blistered nasal fluid flows out from both sides of the nose.
b), Chronic heart failure:
1. The disease progresses slowly and the course of the disease can last for several months or years.
2. The sick dog is depressed and unwilling to exercise. If he exercises a little, he will feel fatigue and difficulty breathing.
3. The mucosa that can be seen in the oral conjunctiva, the veins on the surface of the body are angrily opened, and symmetrical edema is often caused by the extremities, no heat or pain, and the heart sound is weakened. Intracardiac murmurs and arrhythmias can often be heard.
3. Preventive measures for dogs with heart failure:
1. Strengthen nursing: For dogs with acute heart failure, they should immediately rest quietly and stop all training and homework. Give foods that are easily digestible and absorbed. For dogs with difficulty breathing, oxygen should be inhaled immediately to supplement oxygen.
2. Enhance myocardial contractility: For dogs with acute heart failure, fast-acting and efficient cardiac enhancers should be used for first aid.
3. Reduce the heart load: For sick dogs with cardiac edema, appropriately limit the amount of water and salt, and choose appropriate diuretics, which will have better therapeutic effects.
