Hi Matt
It is certainly the case that some small breed dogs and especially short nosed dogs are prone to this kind of symptom, often described as reverse sneezing. The loud noise from the nose and throat in small dogs is often because the soft palate or epiglottis is relatively long, takes up too much space and has got trapped in the wrong position. This flap of tissue back beyond the hard palate(or roof of the dog's mouth)can cover the airway too much, leading to the dog having to make attempts to clear the airway and hence the noisy snorting/sneezing. It is often worse for overweight dogs and if it happens frequently and the dog is getting distressed or unable to exercise properly then corrective surgery is needed. If it only happens occasionally then the dog can usually cope OK.
For your young dog it doesnt sound really bad but its something that you do need to monitor and be aware of. If she's getting more problems over time you will have to see a vet to find out if treatment is needed.
