Abnormal Dentition - Any abnormality of teeth, including number, shape, placement.
Acanthosis nigricans - a skin disease where the skin becomes thickened and dark, primarily affecting the axillae (armpits).
Achondroplasia - abnormal development of cartilage leading to dwarfism (seen aberrantly in most breeds, but that's what makes a Basset hound and other achondroplastic breeds long and low).
Acral lick dermatitis - Skin condition caused by excessive licking of the skin, especially on the legs and paws.
Acral mutilation - Progressive self-mutilation of the feet and legs. May be due to a lack of pain sensation, most common in pointing breeds.
Acute moist dermatitis - Also known as hot spots. Itchy, inflamed dermatitis, usually moist, which is worsened by the dog licking and/or scratching the spot frequently.
Addisons Disease - Also known as Hypoadrenocorticism. Decreased production of steroid hormones by the adrenal glands, producing lethargy, weakness, poor appetite, and even shock and collapse. Can usually be controlled with hormone replacement medications.
Addisons disease (hypoadrenocorticism) - The inadequate secretion of cortisone from the adrenal glands.
Afghan Hound Myelopathy - Degenerative disease of the nervous system usually leading to paralysis and death.
Alport Syndrome - Also known as Hereditary Nephritis. Uncommon sex-linked disease of the blood vessels of the kidney which often leads to kidney failure and death. Females are affected less severely than males.
Amyloidosis - A condition characterized by abnormal tissue deposits of amyloid, a protein like material.
Anasarca - Also known as Water Puppy or Walrus Puppy. An excess accumulation of fluid in a newborn puppy. If severe, the puppy rarely survives.
Anesthetic Idiosyncrasy - An abnormal response to common anesthetics, which can be fatal. At-risk breeds should be tested prior to surgical procedures.

Arteriovenous Fistula - Abnormal connection between arteries and veins which can reduce blood flow to the affected organ or region.
Atrial Septal Defect - A hole in the muscle wall, the septum, which separates the left and right atria of the heart, resulting in abnormal blood flow.
Autoimmune Hemolytic Anemia - Anemia caused by the lysing (rupture) of red blood cells due to an autoimmune response.
Autoimmune Lymphocytic Thyroiditis - Inflammation and eventual destruction of the thyroid gland by a dogs own immune system. Symptoms include weight gain, lethargy, mental dullness, skini problems, behavioral changes.
Avulsion Fractures - A fracture that occurs when a tendon attaching a muscle to a bone tears away part of the bone.
Basal Cell Tumor - Common skin tumor originating from cells of the innermost layer of skin.
Behavioral Abnormalities - Any abnormal or unpredictable behavior.
Bladder Cancer - as in humans, cancer arising from the bladder.
Blindness - Inability to see. Causes vary.
Bloat - A condition where a dogs stomach produces excessive gas and enlarges severely enough to cause death without immediate treatment. Usually associated with gastric torsion

Bundle of His degeneration - Deterioration of part of the hearts electrical system.
