Let you know: Why does the puppy s heartbeat suddenly become very fast?

Just like humans, a dog’s body temperature, heart rate, and respiratory rate have indicators to determine whether they are normal. These things help monitor and regulate the dog’s body functions. But what would be the reason for a puppy’s heartbeat to be extremely fast?

1. Vigorous exercise

When a puppy exercises strenuously, such as running, playing, swimming, etc., it will cause the dog's heartbeat to be extremely fast. This is mainly because when the body is exercising, the heart will increase the heartbeat speed in order to provide more oxygen to muscles and other tissues. This is a normal phenomenon. The owner does not need to worry too much. The heartbeat speed will return to normal after the puppy rests for a period of time.

2. Being frightened

When a dog is frightened, the heart rate will suddenly increase and the breathing will become rapid. In this case, the owner needs to comfort the dog more and spend more time with the dog. The owner's careful care will give the dog a certain sense of security. Moreover, after a puppy is frightened, it will usually have a stress reaction, which will reduce the body's resistance and make it easier to get sick. At this time, the owner should pay more attention to the dog's condition to see if there are any other abnormalities, such as loss of energy, appetite, vomiting, diarrhea, etc. If the situation is serious, it is recommended to send it to a doctor for treatment in time.

3. Suffering from heart diseases

If the puppy has a very fast heartbeat in a calm state, it may be suffering from heart diseases, such as coronary heart disease, cardiomyopathy, arrhythmia and other heart diseases. Due to insufficient heart function, insufficient blood supply causes the dog to suffer from hypoxia. In order to obtain as much oxygen as possible, the dog will increase its heart rate. Specifically, you need to take the puppy to a pet hospital for diagnosis and treatment.
