What is the dog's shortness of breath?

Shortness of breath in normal dogs may be a normal phenomenon after strenuous exercise, and quiet rest can alleviate it. The reason why the dog has been panting and shortness of breath:

1. Due to the hot weather, the sweat glands on the dog's skin are underdeveloped. In hot weather or after exercise, they radiate heat by sticking out their tongues, so they will have difficulty breathing after strenuous exercise.

2, caused by obesity: obese dogs are more likely to pant, because their bodies have difficulty regulating calories.

3, caused by old age: after the dog is old, it will lead to a corresponding weakening of cardiopulmonary function, which will lead to constant panting.

4, caused by stress and fear: When dogs feel stress or fear, they will also be panting, leading to severe panting.
