The following are the more common genetic disorders found in the miniature schnauzer this is not a substitute for full screenings and care you should receive from your vet.







Circulatory System

  • Factor VIII deficiency or hemophilia A: the most common severe inherited clotting disorder of humans and nonhuman animals. Inherited as a sex-linked recessive trait (carried by females and manifested in males). Affects most dog breeds.
  • Hemophilia A: a blood clotting disorder due to deficiency of coagulation factor VIII (this is the most common type of hemophilia in dogs). (See Factor VIII deficiency or hemophilia A.)
  • von Willebrand's 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.
  • 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.
  • thrombocytopenia: a reduced number of platelets in the blood which causes pinpoint hemorrhages in the skin and mucosa. Often accompanies Hemolytic anemiaas an autoimmune syndrome called Evans syndrome. (See Platelet disorder.)
  • Platelet disorder:  a group of abnormalities of small blood cells necessary to control bleeding.
  • Sinoatrial syncope: a condition where the electrical impulses of the heart are abnormal and the animal has episodes of syncope (fainting).
  • Pulmonic stenosis: a condition where one of the valves of the heart does not open properly.


Digestive System


  • Hemorrhagic gastroenteritis: an acute disorder characterized by bloody diarrhea, elevated hematocrit and shock. Common in miniature schnauzers.
  • Esophageal achalasia: a functional structure or spasm of the muscles of the esophagus where it joins the stomach
  • Exocrine Pancreatic Insufficiency -  EPI, Exocrine Pancreatic Insufficiency, is the inability of the acinar cells of the exocrine pancreas to produce and secrete the 3 necessary enzymes needed to digest food


•Amylase for digestion of carbohydrates (sugars & starches in grains, fruits & vegetables),      

•Lipases for digestion of fats and oils,                                                 

•Trypsin and Proteases for digestion of proteins.


EPI, is sometimes referred to as Pancreatic Hypoplasia or Pancreatic Acinar Atrophy (PAA). Or EPI can also be the secondary condition of a chronic illness, such as chronic pancreatitis.



Endocrine System

  • Hypercholesterolemia: a disease where the animal has too much cholesterol in the blood system. Commonly associated with hypothyroidism.

  • Hypothyroidism[1]: a 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 Lymphocytic thyroiditis, Thyroiditis.)

  • Lymphocytic thyroiditis: an autoimmune disease causing inflammation and destruction of the thyroid gland, which becomes infiltrated with lymphocytes (white blood cells) and leads to hypothyroidism. This is the most common endocrine disease of the dog and has an inherited predisposition

  • Thyroiditis:  an autoimmune inflammatory disease of the thyroid gland.


Immune system

  • Allergies: An allergy is an exaggerated immune response or reaction to substances that are generally not harmful. same as in humans. Dogs can be allergic to things they come in contact with, eat or inhale.
  • Food Allergy :

    common food allergies in dogs:
    link 1
    link 2
    link 3
    link 4
  • Atopy : an allergy caused from things dogs inhale. therapy

  • Hemolytic anemia: anemia caused by the destruction of the red blood cells by an autoimmune process. Particularly common in cocker spaniels and Old English sheepdogs, as well as several other breeds.


Muscular System


Nervous System


Ocular System

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


Reproductive System

  • Cryptorchidism: a condition where one testicle does not descend into the scrotal sac.
  • Pseudohermaphroditism (pseudohermaphroditism): a condition where the animal has the gonads of one sex but the appearance is ambiguous or is of the opposite sex.

Respiratory System

Skeletal System

  • 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.
  • Osteochondritis dissecans: a specific form of inflammation of the cartilage of certain joints which causes arthritis. (See Osteochondrosis.)

  • Osteochondrosis: a group of developmental diseases resulting in


    formulation of joint cartilage. Commonly involves the shoulder, stifle, hock or elbow.  (See # Osteochondritis dissecans.)


Skin / Integumentary System

  • Distichiasis: abnormally growing eyelashes.

  • Entropion: an abnormal rolling in of the eyelid.

  • Aurotrichia :  Only affects miniature schnauzers : Patchy change of coat color to 'gold'. Thinning of secondary hairs.

  • Flank alopecia: Seasonal flank alopecia is exactly what it sounds like, though it helps to know that alopecia means hair loss. With seasonal flank alopecia, a dog loses hair in the flank area on a seasonal basis.
  • Schnauzer comedo syndrome: a skin disease of schnauzers where the skin forms comedones ("blackheads").

  • Subcorneal pustular dermatosis: a skin inflammation occurring between certain layers of the skin.


Urinary System

  • Cystitis and cystic calculi: infection of the bladder which often leads to formation of abnormal mineral deposits (bladder stones)
  • Renal dysplasia: a condition where the kidneys form abnormally. Renal failure develops with protein loss in urine.
