Dogs + Medical Conditions

  • Prostatic disease can be uncomfortable for a dog, particularly if it causes compression of the urethra or colon. Because there are many diseases of the prostate, it is necessary to perform several tests to determine the exact cause of a patient's condition. This handout provides explanations of the seven most common conditions affecting the prostate and the corresponding approaches to treatment.

  • 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 (itching) is a very common skin disorder that can be seen due to allergies or infections affecting the skin. The condition may be resolved if an underlying cause can be identified. Consult your veterinarian about what can be tested for and what treatments can be effective for relief.

  • Pulmonary hypertension means that the peak blood pressure in the arteries of the lungs is much higher than normal. Several abnormalities can lead to high blood pressure in the arteries of the lungs and many of the underlying reasons involve the heart. There are many signs of pulmonary hypertension including exercise intolerance, difficulty breathing with or without exertion/exercise, rapid breathing, coughing, spitting up blood from the lungs, fainting, and more. There are many potential causes of pulmonary hypertension. Several medications are available to treat your dog. It is important to maintain a low-stress environment while any underlying cardiac or respiratory disease is treated and managed. Activity may need to be restricted. It is essential to monitor dogs with pulmonary hypertension for worsening of clinical signs. Periodic physical examinations, blood pressure monitoring, and ultrasound evaluations of the heart will also be important. The long-term prognosis is very guarded for dogs with pulmonary hypertension.

  • Pulmonary thromboembolism describes a condition in which a blood clot lodges in one of the pulmonary arteries, blocking blood flow into the portion of the lung served by that artery. The signs of pulmonary thromboembolism include sudden difficulty breathing, rapid breathing, decreased appetite, fainting, coughing, spitting up blood, weakness, exercise intolerance, and the inability to get comfortable. Sudden death is possible. This article discusses potential causes, treatment, and prognosis.

  • Pyelonephritis is an upper urinary tract infection. Many dogs have no clinical signs when they have pyelonephritis, although they may have signs of lower urinary tract disease. Pyelonephritis is usually caused by a bacterial infection that moves up the urinary tract from the bladder to the kidneys. There are several developmental, medical, and procedural conditions that increase the risk for pyelonephritis. Antibiotics are used to treat pyelonephritis and are chosen based on testing the urine for bacteria and antibiotic sensitivity. Overall, dogs with sudden pyelonephritis do well and return to normal health with appropriate treatment unless they also have kidney stones, chronic kidney disease, urinary tract obstruction, or cancer in the urinary tract.

  • Pyoderma is a bacterial skin infection that can affect all areas of the skin, including skin folds, often seen as red, pus-filled pustules. Treatment may require oral or topical medications and it is always a good idea to practice good hygiene. Pyoderma carries a good prognosis for recovery but recurring or chronic cases may require longer treatment and additional testing to determine an underlying cause.

  • Pyometra is a serious and life-threatening infection in the uterus, occurring in female dogs who have not been spayed. The condition must be treated quickly and aggressively. The preferred treatment is to surgically remove the uterus and ovaries by performing an ovariohysterectomy. There is a medical approach to treating pyometra, although the success rate is highly variable and not without considerable risk and potential long-term complications.

  • Pyothorax occurs when pus or inflammatory fluids collect in the space around the lungs causing fever, anorexia, lethargy, and difficulty breathing. It is diagnosed through history, physical exam, radiographs, and thoracocentesis. Treatment with oral antibiotics is essential and may involve repeated thoracocentesis or the placement of a chest drain.

  • Pythiosis is a waterborne infection that can infect the GI tract or skin of dogs. It can cause extreme weight loss, vomiting, diarrhea or skin lesions such as ulcerating nodules and draining tracts. This disease is more common in southern regions. Treatment involves surgical removal of all affected material if possible, including limb amputation if indicated. Different antifungal therapies have shown some efficacy and need to be continued long-term. Prognosis for resolution of pythiosis is guarded to poor.
