  • Pyothorax is the presence of inflammatory fluid or pus within the chest cavity, usually caused by a bacterial infection. This handout outlines causes, signs, treatment, and prognosis.

  • Pyothorax is the presence of inflammatory fluid or pus within the chest cavity, usually caused by a bacterial infection. This handout outlines causes, signs, treatment, and prognosis.

  • Quittor is an old term for a condition that involves death and destruction (necrosis) of the collateral cartilages of the foot (see our information sheet on sidebones), following an infection in the foot (see our information sheet on pus in the foot).

  • A recessed vulva, also called a juvenile or hypoplastic vulva, is an anatomical condition in which a female dog's vulva is partially hidden by surrounding skin folds. It is more common in medium to large breed dogs, especially if overweight. The prognosis for this condition depends on its severity and which treatment option is attempted.

  • 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.

  • RAO (previously called chronic obstructive pulmonary disease or COPD) is a relatively common cause of coughing and nasal discharge in stabled horses. In long-standing cases the horse may have difficulty in breathing and its chest and abdomen can be easily seen to move, hence the even older name 'heaves'.

  • 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.

  • Dystocia means difficulty giving birth or abnormal delivery. In reptiles that do not give live birth, dystocia may also be called egg binding or ovostasis. It is a relatively common problem in reptiles, and can be life-threatening. Any signs of abdominal swelling need attention.

  • Swellings on or around the joints in reptiles can be an indication of uric acid deposits in the area. This condition is referred to as gout. Gout is often painful and may also affect internal organs. Treatment will require medications and sometimes surgery.

  • Respiratory disease is common in birds and can be caused by infection with bacteria, fungus, or parasites; by exposure to aerosolized toxins or environmental irritants; or by pressure on the respiratory tract from enlarged organs or tumors. Birds can have varying signs, such as coughing, sneezing, ocular or nasal discharge, or difficulty breathing. Any bird showing respiratory tract signs should be examined and tested by a veterinarian as soon as possible. Over-the-counter medications from pet stores are not recommended for treating sick birds.
