Immune System Issues in Yorkies

Yorkshire terriers, or Yorkies, are predisposed to certain immune system disorders. Some of these disorders are genetic and some are simply due to the size of their body. Knowledge and awareness are the best resources for keeping your pet healthy and knowing what to do in case of an onset of symptoms. It is important to be aware of these potential conditions when deciding on a family dog to make sure the extra care needed will fit into the family's lifestyle.

  1. Autoimmune Thyroiditis

    • The thyroid gland controls many bodily functions such as regulating metabolism and energy levels. Dogs with thyroiditis produce antibodies to the thyroid gland and hormones in the dog's blood. These hormones destroy the gland tissue. The body isn't able to produce the antithyroid antibodies once the gland is destroyed. The dog then becomes lethargic, weak or obese. The dog can also develop skin and coat disorders or behave abnormally and become infertile. This is important to know in the event of breeding. Treatment consists of a thyroid supplement.

    Shaker Dog Syndrome

    • Shaker dog syndrome is a neurotransmitter deficiency resulting from an autoimmune reaction. This disorder develops without warning primarily in dogs ranging from six months to 3 years of age. Dogs experience tremors that affect the whole body and some even have difficulty walking. Excitement and stress make this condition worse. Seizures, head tilts and weakness are also symptoms. Diagnosis is made primarily on the clinical signs. Medication such as steroids are used to treat this disorder.

    Demodectic Mange

    • Demodex mites live inside hair follicles of most dogs and even on humans. These tiny mites look like miniscule alligators. Demodectic mange occurs when the dog isn't able to keep the mites under control due to either an undeveloped or suppressed immune system. The symptoms include red, crusty skin and hair loss, usually beginning on the head. A veterinary diagnosis is necessary through a skin scraping or biopsy. The treatment involves shampoos, lotions and dips.

    Idiopathic Polyarthritis

    • Idiopathic polyarthritis is an autoimmune condition that commonly affects Yorkshire terriers. This disorder attacks the joints in the dog. The symptoms include loss of appetite, fever, swelling and lethargy. The dog will appear lame and stiff. Steroids are used to treat this autoimmune disorder.
