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.

A recessed vulva, also referred to as a juvenile or hypoplastic vulva, is a conformational issue that occurs in female dogs. In this condition, the vulva is recessed within, or partially hidden by, surrounding folds of skin. Some dogs might have a recessed vulva for their entire life without ever experiencing any visible effects. In other dogs, however, a recessed vulva can predispose them to vaginitis and/or urinary tract infections. Depending on the severity of your dog’s clinical signs, medical or surgical options may be used to treat this condition.

Cryptorchidism is the failure of one or both testicles to descend into the scrotum. Toy breeds may be more at risk, but it can affect any breed of dog and is believed to be an inherited trait. Diagnosis can usually be made by palpation but sometimes requires blood testing or an abdominal ultrasound if the dog’s history is unknown. Risks of retained testicles include testicular cancer, spermatic cord torsion, and the development of undesirable male characteristics, so neutering is strongly recommended. Surgery is generally routine, and recovery is similar to any abdominal surgery.

Some dogs have a condition known as paroxysmal respiration, more commonly called reverse sneezing. With this condition, the dog rapidly pulls air into the nose, whereas in a regular sneeze, the air is rapidly pushed out through the nose. The dog makes a snorting sound and seems to be trying to inhale while sneezing.
