Teacup Yorkies are not an official breed as Yorkshire terriers must be between 4 and 7 lbs. to be AKC registered. Many people, however, enjoy the company of these miniature versions of the breed. The health problems for both miniatures and standard Yorkies are the same.
Hypoglycemia, or low blood sugar, often will arise between birth and 4 months of age. Adult Yorkies also can develop hypoglycemia, although it does not happen often. Symptoms include shaking, seizures, fainting, depression and sometimes coma.
Legg-Perthes Disease is a disease of the hip joints brought on by poor circulation, which causes the cartilage to tear or crack. Symptoms include limping, pain and lameness in the leg.
Retinal Dysplasia is an irregularity of the retina of the eye that is usually inherited. This will usually cause vision problems and can lead to blindness. Symptom include confusion, bumping into objects, and difficulty negotiating stairs and obstacles.
Luxating patella, or kneecap dislocation, is when the kneecap slips out of place. If not treated, it can lead to lameness and loss of motor function in the legs affected. Symptoms include limping, a skip-like walk and desire to not bend the hind leg.
Very common in small dogs, a collapsed trachea can cause breathing problems. It can be caused by walking a dog on a leash and collar as opposed to using a harness and leash. It also is caused by a softening of the cartilage rings that surround the trachea. Symptoms include noisy breathing, coughing, breathing difficulties, gagging and blue gums.
A portosystemic shunt is an inherited disease in which the portal vein has an abnormality. Symptoms include behavioral changes, loss of appetite, decrease or loss of coordination, sporadic vomiting, small body size, weakened muscles and drooling.
