  • Pleural effusion refers to the abnormal accumulation of fluid within the chest cavity. The fluid is not found within the lungs, but instead within the pleural sac, essentially meaning the lungs are floating in a chest that is full of fluid. Several conditions can cause pleural effusion, including chylothorax, heart failure, and tumors in the lungs or chest wall. Immediate treatment often requires oxygen support and the removal of the excess fluid by thoracocentesis, which can also then be tested to diagnose the cause of the pleural effusion. Treatment and prognosis vary depending on the underlying cause of the pleural effusion.

The fluid is not found within the lungs, but instead within the pleural sac, essentially meaning the lungs are floating in a chest that is full of fluid. There are several causes, including chylothorax, heart failure, and lung or chest tumors. Dogs presenting for pleural effusion are often experiencing shortness of breath and decreased oxygen intake; placing them into an oxygen cage provides some degree of immediate relief. Removing the fluid that surrounds the lungs will allow the dog to breathe more readily and this fluid can then be tested to identify the cause of the pleural effusion. The treatment and prognosis vary depending on the underlying cause.

  • Pneumothorax is an accumulation of air outside the lungs, but inside the chest wall. The air outside the lung prevents the lungs from inflating normally, and can lead to lung collapse. There are several variations of pneumothorax.

  • Porcupine quills can puncture the skin and move through muscle, ultimately penetrating into body cavities and internal organs. They contain barbs like fishhooks and tend to migrate inwards instead of being expelled. Do not cut quills or attempt to remove the quills yourself. Seek immediate veterinary care if your dog is quilled. Sedation or anesthesia is required to remove quills safely.

  • 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.

  • Pyometra is a serious and life-threatening infection in the uterus, occurring in female cats 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 is the presence of inflammatory fluid or pus within the chest cavity, which is the area between the lungs and the inner walls of the ribs. Signs of pyothorax include rapid, shallow, open-mouthed breathing that may be painful, depression, lethargy, decreased appetite. Clinical examination by a veterinarian, particularly listening to the chest with a stethoscope, may indicate fluid in the chest.

  • 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.
