What's wrong with dogs always sleeping in summer?

First of all, we must rule out whether we are sick or not. If the stool can take shape, the body temperature is normal and you don't cough, there should be no problem.

2. Is it that the dog can't sleep because it is fed too much?

3. Another possibility is that dogs are not adapted to the new environment and are afraid. If time permits, take more time to play with the dog. The owner can run in front and the dog can chase after him. Play this game as much as possible, and the dog will gradually become lively.
