Medical Conditions

  • Pyelonephritis is an upper urinary tract infection involving the kidneys and ureters. Many cats 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. Cats with sudden pyelonephritis do well and return to normal health unless concurrent complications exist.

  • 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 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. 

  • 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 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.

  • 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.

  • In the wild, a bird will try to uphold a strong appearance when sick. By the time a pet bird begins to display symptoms of illness, it has likely been sick for several days to weeks. Many things contribute to ill health. This handout provides bird owners with a list of signs that will alert them that their bird is sick.

  • Reproductive disease in ferrets is rare today, as most pet ferrets are spayed or neutered at a young age. One disease that is still occasionally seen in pet ferrets occurs in females that are not spayed. This is called hyperestrogenemia and is a result of persistently high blood levels of estrogen in unspayed females that are not bred or fails to ovulate.
