By the way, is it normal for dogs to snore while sleeping?

It is very normal for dogs to snore while sleeping. Any creature with a nose may snore.

The reasons why dogs snore are:

1. Flat face. Most breeds with very short muzzles have snoring problems.

2. Loose organization. Loose throat tissue can also cause snoring because these loose tissues vibrate more easily when breathing.

3. Obesity. If your dog is obese, fat may accumulate in the throat, making the airway smaller. Airway obstruction can cause surrounding soft tissue to vibrate, causing snoring.

4. Allergies/diseases. Dog snoring can also be caused by a more serious problem, namely disease, as allergies or other respiratory problems can also cause snoring. If your dog didn't snore before and suddenly snores now, it's best to take your dog to the vet.

5. Sleeping style. Some dogs only snore when they sleep on their belly. At this time, using a ring bed to let the dog curl up to sleep to change its sleeping pattern can effectively eliminate snoring.
