Question

Why is my dog snoring more?

Answer 1

According to VetInfo.com, dog snoring is caused by an obstruction in the nasal passage or nostrils that leads to airway constriction.

The site lists some of the causes for dogs to snore: Overweight dogs can have excess tissue in the throat.

This presents obstructions that block the airway.

Answer 2

Just like with humans, snoring in dogs generally occurs when air movement is restricted in the nasal passageways or throat. Some of what can cause dogs to snore may simply be that they like to sleep on their back, so their tongue ends up partially blocking some of the air movement in their passageways.
