Breed Overview

• The Yorkshire terrier, originating in Yorkshire, England, is classified as a small dog by the American Kennel Club and was first recognized in 1885. The Yorkshire terrier breed, like all purebred dogs, is predisposed to many ailments such as Prototsystemic Shunts, Canine Hypothyroidism, and Renal Failure (kidneys). Yorkshire terriers, also known as "Yorkies," are also at risk for generalized physical injury (broken bones from falls, etc.) due to their small stature.
  
  

Hair Loss Appearance

• Hair loss in Yorkshire terriers is typically a serious sign of illness and should be reviewed by a qualified veterinarian. Hair loss in Yorkshire Terriers can range in appearance. Hair may thin in specific zones of the blue or fawn tones of the coat (typically in younger dogs around six months of age), or begin on the underbelly and move upward toward the top of the dog's back. Hair loss is not normal and is usually the first warning sign.
  
  

Causes

• Hair loss in pet Yorkshire terriers can be a result of several conditions including, but not limited to, Cushings disease (generally caused by tumors on the pituitary or thyroid glands) and color dilution/mutant alopecia, which causes hair in the blue and fawn zones to thin, often followed by a secondary folliculitis (irritation/pimples). Excessive brushing of the animal's coat can be a cause of hair loss. Consult your veterinarian regarding the proper amount of brushing your pet's coat can handle.
  
  

Diagnosis

• The diagnosis of any ailment presenting through your pet should be conducted by a qualified veterinary professional. Symptoms of conditions often overlap and may require confirmation through blood tests. Owners do, however, provide essential information to veterinarians during their diagnosis. If you notice any changes in your pet's behavior, jot down notes including time, date and any preceding behavior that you may have observed. Building a time line of events will help veterinarians with a better overall picture of your dog's health.
  
  

Treatment

• The treatment of hair loss in a Yorkshire terrier can vary depending on the cause. If this a hereditary condition, few options exist. If your veterinarian has diagnosed a specific illness, treatment can range from pharmaceutical interventions to surgery. Yorkshire terriers have a poor tolerance of anesthesia, which can sometimes rule out the option of surgery. For this reason, some Yorkshire terrier owners prefer to manage the symptoms through diet whenever possible.
