Don't be ashamed! It's all in name of veterinary client education.
We want to help you make your best impression in the exam room-impression of a reverse sneeze, that is. We caught some of your veterinary colleagues on camera imitating this odd clinical sign as inspiration.
(Thanks to Dr. Kathryn Primm for her excellent coaxing skills!)
[Ahem.] On a more serious note, you can download this client handout on reverse sneezes to alleviate client alarm when faced with a bout of this respiratory oddity.
