Dogs + Medical Conditions

  • Polycythemia vera, or “true” polycythemia, is a rare disease of dogs and cats in which too many red blood cells (RBCs) are produced by the bone marrow. This is the opposite of anemia, in which there are too few red blood cells.

  • The portal vein is a large vein that collects blood from the systemic circulation and carries it into the liver, where toxins and other byproducts are removed. A liver shunt occurs when an abnormal connection persists or forms between the portal vein or one of its branches, and another vein, allowing blood to bypass or shunt around the liver.

  • In 2016, researchers identified a gene, called the pro-opiomelanocortin (POMC) gene, that contributes to obesity in Labrador Retrievers. A specific mutation of this gene, involving the deletion of 14 DNA base pairs, has been shown to contribute to increased body weight, increased body fat percentages, and increased food motivation in Labrador Retrievers.

  • Progressive retinal atrophy, shortened to PRA, is a group of degenerative diseases that affect photoreceptor cells. With this disease, the cells deteriorate over time, eventually leading to blindness in the affected dog.

  • The prostate (commonly miscalled the "prostrate") is a small gland located near the neck of the urinary bladder of male dogs. The urethra (the tube that carries urine from the bladder to outside the body) passes through the prostate shortly after leaving the bladder.

  • The word “enteropathy” means any disease of the intestinal system. Protein-losing enteropathy (PLE) is not a specific disease, but rather describes a group of diseases that cause the loss of proteins from the bloodstream into the gastrointestinal (GI) tract.

  • Pruritus is the medical term for itching. It is common in many types of skin disorders. Itching and scratching are commonly associated with flea allergy dermatitis and other allergic skin diseases.

  • Pulmonary hypertension means that the peak blood pressure in the arteries of the lungs is much higher than normal.

  • “Pulmonary” means lung, and the word “thromboembolism” describes a blood clot that has moved through the blood vessels, lodged in one of the pulmonary arteries, and blocked blood flow into the portion of the lung served by that artery.

  • Pyelonephritis is an upper-urinary tract infection. The upper urinary tract consists of the kidneys and the ureters (the tubes that carry from the kidneys to the bladder).
