As with all other breeds of dog, the Yorkshire Terrier is susceptible to a variety of different health problems. Due to the extensive line-crossing and inbreeding that commonly occurs in pedigreed dogs, as well as the unethical practices of some breeders, one must take care when selecting a Yorkshire Terrier puppy. Here are some of the conditions that the breed is more susceptible to:

Collapsing Trachea
Cushing’s Disease
Eclampsia
Hemorrhagic gastric enteritis (commonly known as HGE)
Hypoglycemia
Legg-Calve-Perthes (LCP)
Liver shunts
Pancreatitis
Luxation of the patella
Pharyngeal gag reflex (sometimes called reverse sneezing)
