Reverse sneezing itself rarely requires treatment. If the sneezing stops, the spasm is over. Oftentimes, you can massage the dog’s throat to stop the spasm; sometimes it’s effective to cover the nostrils, which makes the dog swallow, which clears out whatever the irritation is and stops the sneezing. If the episode doesn't end quickly, you can try depressing the dog’s tongue, which opens up the mouth and aids in moving air through the nasal passages. Treatment of the underlying cause, if known, is useful. If mites are in the laryngeal area, your veterinarian may use drugs such as ivermectin to get rid of the mites. If allergies are the root of the problem, your veterinarian may prescribe antihistamines. Because reverse sneezing is not a severe problem, do not worry about leaving your dog home alone; if it occurs when you're not there, the episode will most likely end on its own.

Rhett get's the reverse sneezing this time of year, too, from all the pollen. He always looks so miserable while it's going on. We will be doing antihistamines this spring to try and make him more comfortable.

If it hasn't let up by this morning, a quick trip to the vet to rule out him having aspirated a piece of grass might help set your mind at ease.
