Irritants like dust, pollen, foreign objects, etc. can trigger spasms resulting in reverse sneezing.
Reverse sneezing episodes typically only last around 30 seconds or less.
Smaller breed dogs and those with elongated nostrils are prone to frequent reverse sneezing.
Normal in Some Dogs
Though jarring, reverse sneezing isn't usually dangerous. Stay relaxed to avoid worrying your dog more.
Lightly massage the throat to help relax muscles and open airways.
Gently Massage Throat
Blowing gently on your dog's face helps interrupt the spasm.
Blow Air In Face
Control dust and switch to unscented laundry detergent if those seem to trigger episodes.
