Actually it is rather common for the breed. When they get excited their trachea will collapse. It is most common in toy breed dogs but can occur in larger breeds at times. It is likely that this condition is partially the result of breeding for small size. It is reported to be most common in Yorkshire terriers, poodles, Chihuahuas, pugs and Pomeranians have been reported to be the breeds most commonly affected by this condition (Slatter's Textbook of Small Animal Surgery) but it is reasonably common in all the toy breeds and several other smaller dog breeds.
