Why Does My Dog Snore in Its Sleep?

Dog snoring usually means the upper airway has narrowed so throat tissue vibrates, but the trigger varies: a lodged object, a long soft palate in flat-faced breeds, excess weight, smoke or air pollution, infection, or simply sleeping on the back. Judge by the cause. Fix posture for back-sleepers, slim down an overweight dog, raise room humidity, and for flat-faced breeds ask a vet about trimming an over-long palate. Occasional snoring is usually fine.
