Reverse sneezing is very common in small dogs. Chihuahuas can be more susceptible because of their size; but any dog may have a bout of reverse sneezing. Being able to spot whether your chihuahua is having a bout of reverse sneezing or suffering from tracheal collapse is the key.

When it first occurs, it can be very frightening to watch. As opposed to a typical sneeze where the air is pushed out through the nose in a reverse sneeze, air is pulled in while dogs are expanding their chest and extending their neck.

The result is a snorting sound which can startle pet owners and looks very alarming.

When does reverse sneezing occur?

Reverse sneezing will be triggered by an event and can last just one sneeze or continue for over a minute. Triggers will include allergens, such as seasonal pollen, strong odours such as perfume or a cleaning products or when your chi is excited. Dogs can get hayfever as well.

Reverse sneezing is a relatively normal event for dogs, and while it may look like your chihuahua is choking from their stance and sounds, they will go on to breathe normally after the event as if nothing happened. I am convinced Minnie does it when she's not getting her own way!

Reverse sneezing might worry you, more than it bothers your chihuahua, so monitoring what they are doing when they reverse sneeze will help you to identify triggers to put your mind at ease. Once you know what starts the sneezing, you can find ways to avoid it.

When reverse sneezing is tracheal collapse

While reverse sneezing is harmless, other respiratory problems are not. It is important to keep a look out for your chihuahua during a reverse sneezing attack in case it is the sign of something more concerning.

A tracheal collapse is a where the usually strong rings of cartilage surrounding the trachea (windpipe) weaken and collapse. Unfortunately, it is much more common in toy breeds such as chihuahuas and Yorkshire terriers.

As a tracheal collapse is a stressful disease that can worsen over time, it’s important for all chi owners to be aware of the problem so they can act fast as soon as they notice symptoms.

A tracheal collapse starts in the same way as for reverse sneezing with the unusual snorting sound; the sounds are from a persistent and chronic cough or chronic reverse sneezing. As well as the honking sound, you will also notice lethargy and a difficulty in breathing. In some cases, your chihuahuas gums may turn blue.

Can you cure it?

Reverse sneezing is perfectly normal and will not require any treatment, just try to avoid the triggers, and your chi should be fine. If you notice reverse sneezing is becoming chronic, then a visit to the vet is a good idea to rule out any respiratory problems.

The only option if medication isn’t successful is surgery, where the vet replaces the collapsed cartilage rings with artificial rings to support breathing.

Can tracheal collapse be avoided?

A collapsing trachea is often hereditary and unable to prevent. For when it isn’t genetic, chihuahua owners can take precautions through using a harness and lead instead of a collar and keeping your chi at a healthy weight.
