I get daily inquiries about reverse sneezing in dogs this time of year. So what is a reverse sneeze? This is an act that your dog may display when trying to clear their throat. Most dogs will extend their neck and suck air in through their nose. This can last for a few seconds or it can last several minutes, or it can occur throughout the day. Most dogs that have reverse sneezing are just trying to clear their throat due to sinus drainage, inflammation in the back of the mouth, allergies, etc. This is not a life threatening issue but can become a burden to owners and dogs if it is severe. You can go to YouTube and watch videos of dogs with a reverse sneeze to see it in action. As far as treatment goes, you need to calm the dog down by rubbing his/her neck and throat area, then you can try antihistamines to dry up the sinus. If the sneezing continues, always check with your veterinarian to see if other medications might be warranted to help with the inflammation.
