Medical Conditions + English

  • 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.

  • Abdominal swelling in any reptile is always a concern that needs to be brought to the attention of a veterinarian well versed in reptile medicine. In female reptiles, this swelling often means that the individual has eggs or fetus that are ready to be delivered. When the female cannot deliver the eggs or babies, this is referred to as dystocia. This condition can be life threatening and need attention ASAP.

  • 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.

  • Respiratory disease in ferrets is common. Several infectious/contagious conditions like distemper and influenza can be life threatening for ferrets. Like dogs and cats, ferrets can develop heartworm disease, even indoors. Lymphoma, a cancerous condition of lymph organs can cause disease in the chest cavity.

  • 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.

  • Ringworm infections in cats are caused by a fungus, not a worm. They can be easily recognized, though definitive testing by fungal culture is recommended. Ringworm is highly contagious and can be spread between animals and from animals to people. The clinical signs, diagnosis, treatment, and risks are explained in this handout.

  • Round cell tumors are among the most common skin tumors in dogs, and they typically form just under the skin, although they may change the surface of the skin above them. It is impossible to diagnose any of them without a veterinary pathologist analyzing a tissue sample of the tumor under a microscope. If detected early, most round cell tumors can be easily removed.
