Symptoms of heart problems in dogs:

1. Cough

The most common symptom of dogs with heart disease is coughing . Most of the time it is a dry cough, and occasionally a wet cough. No matter what, it is abnormal for a dog to cough. Therefore, if your dog does develop a cough for any reason, especially if your dog has been previously diagnosed with a heart murmur, you should see your veterinarian as soon as possible.

2. It gets tired easily

If you take your dog out for a walk and notice that it is not as normal as usual. After just walking two blocks, it gets tired and stops or sits down. This is Probably means it's more tiring than before. Although there are several reasons for this easy fatigue, the weakening of the myocardium caused by heart disease is the primary cause. You should go to the pet hospital for examination.

3. The abdomen becomes enlarged

The weakening of the myocardium caused by heart disease will also lead to poor forward blood flow, which will lead to abdominal fluid accumulation. This manifests as a sudden or gradual onset of a potbelly.

4. Increased respiratory rate

This is the most subtle signal that is difficult to detect, but it is also reliable. If you do not observe carefully, it is difficult to notice. Pay more attention to your dog's breathing rate when resting, so that if you find such signs in the future, you can be aware in advance that this may be the cause of heart disease.

5. Fainting and fainting

This is a very rare symptom. When a dog is very excited, it may faint directly. This is a very serious symptom and requires your dog to be checked immediately.
