Yorkshire terrier: 42, 57, 70, 71, 80, 88, 103, 149, 154, 160, 162, 166, 179, 181, 185, 199a, 235, 236, 245, 252a, 256, 269, 270, 276, 313, 330

42. Cataract: as in humans, a change in structure of the lens of the eye leading to cloudiness and usually to blindness.

57. Collapsed trachea: a condition where the cartilage rings that make up the trachea are malformed and tend to collapse easily

70. Cryptorchidism: a condition where one testicle does not descend into the scrotal sac.

71. Cushing's disease (hyperadrenocorticism): a common disease characterized by an
excess secretion of corticosteroids from the adrenal glands. Most often seen in middle aged females. (See #156)

80. Demodicosis: a kind of skin disease (mange) caused by microscopic

Demodex canismites living within the skin layers and producing an immunodeficiency syndrome.

88. Distichiasis: abnormally growing eyelashes.

103. Entropion: an abnormal rolling in of the eyelid.

149. Hepatic portosystemic shunt or arteriovenous fistula: a malformation of blood vessels in the liver or an abnormal communication between the arteries and veins in the liver. (See #199a, 252a)

154. Hydrocephalus: a condition where there is an abnormal accumulation of fluid in the ventricles of the brain.

160. Hypoglycemia: a syndrome where the animal has an abnormally low blood glucose.

162. Hypoplasia of dens: a condition where part of the second vertebra fails to develop fully and leads to instability.

166. Hypothyroidism: a very common endocrine disease where the body produces an
abnormally low amount of thyroid hormones. An autoimmune destruction of the thyroid gland which affects more than 50 dog breeds. (See #192, 312)

179. Keratitis sicca: a condition where one or both eyes do not produce a normal amount or type of tears. (See #181)

181. Keratoconjunctivitis sicca: Also called “dry eye”, and associated with hypothyroidism in some breeds such as the American cocker spaniel. (See #179)

185. Legg-Perthes disease: a disease where the blood vessels feeding the femoral head (top part of the thigh bone) shrink, leading to starvation and death of the femoral head (the ball of the ball-and-socket joint of the hip). Also called Legg-Calve'-Perthes disease. Most common in large breeds.

199a. Microvascular dysplasia: (See #252a)

235. Patella luxation: a condition where the knee caps slide in and out of place.

236. Patent ductus arteriosus: failure of the vessel remnant joining the aorta and pulmonary artery in fetal life to close properly at birth, thereby shunting blood away from the lungs.

245. Persistent pupillary membrane: a developmental abnormality where the membrane
forming the iris does not form properly.

252a. Portosystemic shunt: a congenital anomaly of blood vessels supplying the liver, causing varying degrees of liver dysfunction or failure. Also can be manifested as microvascular dysplasia. Common in breeds such as the Yorkshire and Cairn terrier, but can occur in any breed. (See #149, 199a)

256. Progressive retinal atrophy: a disease where the retina slowly deteriorates, producing night blindness.

269. Retinal detachment: where the retina is unattached to the back of the eye.

270. Retinal dysplasia: a condition where the retina is malformed.

276. Seborrhea: a skin disease with excess scaling of the skin and often an excess of sebum (oil-like substance) and odor.

313. Tracheal collapse: (See #57)

330. von Willebrand disease: a type of bleeding disorder caused by defective blood platelet function. Occurs in 59 dog breeds but most often in Doberman pinschers. An autosomal trait affecting both sexes.

Great job, Carolyn.

Our Vet explained the reason she did the 1st Schirmer tear test was because Max's left eye was so dry.

Sheila had sent the breeder all the information and included a link about it.

She couldn't understand how the breeders Vet missed it.

It's sad that it went undiagnosed so long, that he developed the bacertial infection in his left eye.

Now his right eye has it. So, I am treating both eyes.

She e-mailed me yesterday evening, and I replied and told her that I am not sending her Maxwell's medical records, until she sends me his medical records from her Vet.
