Snorting: Some Cavalier King Charles Spaniels will snort, especially when excited. This is a common condition in all short-nosed breeds. It may seem like an asthmatic episode, but the condition is not dangerous. Simply place your hand over your Cavalier King Charles Spaniel's nostrils and muzzle for a few seconds and restrict the intake of air and the snorting should stop. It can sometimes take a couple of tries, but if the symptoms occur along with lack of appetite or a persistent cough seek a veterinarian's assistance.
