Is it normal for dogs to snore in their sleep

It is normal for dogs to snore in their sleep, mostly for the following reasons: 1. short nasal cavity: for example, pugs and pitbulls, most of them have snoring problems, because a short nasal cavity can lead to a narrow airway; 2. obesity: if a dog is too obese, there is more fat in the throat and the soft tissues around it are loose, which may also compress the airway and can easily lead to snoring; 3. sleeping position: some dogs like to sleep on their backs, which can also make snoring worse. In addition, there may be allergies that cause snoring, but most of them do not occur only during sleep, mainly due to allergies that cause redness or inflammation of the larynx, thus narrowing the airway and making breathing difficult, resulting in snoring. You need to go to the hospital as soon as possible.
