Why do pugs sleep so much?

Answer 1

Their face is very squished which blocks their nasal passages a bit making them snore. They can also snore when their throats are resting on something because it also blocks up their breathing passages too. Don't worry unless the pug is always gasping for air. Because it can be hard for them to breathe, it is best not to get a pug for intense activities for long periods of time.

Answer 2

They can't breathe well and the lack of oxygen cuts off the brain activity so they sleep more than other dogs.

Answer 3

They can't breathe well.
