Yes the videos work. Poor little girl (though she is a cutie!) - have you looked up reverse sneezing on youtube/this site to compare?
Sure sounds like it to me - reverse sneezing actually has nothing to do with sneezing, but is a spasm caused by an irritation of the soft palate.
'The soft palate is a soft, fleshy tissue extension off the hard palate, or roof of the mouth. Small dogs in particular can exhibit this behavior and certain breeds may be predisposed to it.
Some animals can have this condition for their entire lives, or it may develop as the dog ages. During the spasm, the dog will usually turn her elbows outward and extend her neck while gasping inwards with a distinctive snorting sound. Gently massaging the throat area or pinching the dog's nostrils shut so she must breath through her mouth can help shorten the episode. Sometimes taking the dog outside in the fresh air stops the spasm. Once the attack ceases, all goes back to normal.
It is thought that the pharyngeal spasm can be caused by a number of irritants, including dust and pollen, or household chemicals. Moreover, some dogs can launch an episode after eating, drinking or running around, or while pulling on the leash.
Reverse sneezing appears a lot worse than it is, generally posing no health threats whatsoever. Typically, an episode of reverse sneezing will end soon on its own. Nevertheless, understanding and recognizing the syndrome can go a long way toward helping dog owners and their dogs cope with it. '
