Medical Conditions

  • Cataract formation is a reasonably well-known occurrence in pet birds. Canaries are more prone to cataract formation than other species of birds. Cataracts may be inherited or be secondary to a traumatic injury or infection involving one or both eyes.

  • Inside the eye is a lens that focuses light on the back of the eye, or retina. Vision occurs at the retina. The structure of the eye is similar to a camera, which has a lens to focus light on the film. A cloudy or opaque lens is called a cataract.

  • The intervertebral discs allow movement in the spine and act as shock absorbers between the vertebrae. If the disc degenerates or is damaged in some way, the disc may bulge and put pressure on the spinal cord and/or the roots of the spinal nerves that come off the sides of the spinal cord. This pressure can cause symptoms ranging from severe pain to weakness to paralysis. There are several breeds that experience a higher frequency of the condition. The severity of a dog’s clinical signs depends upon several factors. Conservative management with pain relievers and anti-inflammatory medication is recommended with a gradual onset of clinical signs or when clinical signs are limited to pain and/or a mildly wobbly gait. Surgery is recommended when there are repeated episodes of neck pain, when neck pain is severe, when there are severe nervous system deficits, or when the dog has not responded to conservative treatment.

  • Cervical vertebral instability (wobbler syndrome) is caused by compression of the spinal cord, usually at the base of the neck. Although the spinal cord compression occurs in the neck, the hind legs are often affected first. In severe cases, the dog may suddenly develop total paralysis of all four limbs. The condition is most prevalent in Great Danes and Doberman Pinschers. Most pets enjoy a relatively normal lifestyle following surgery.

  • Chameleons may be affected by a variety of medical conditions. A swollen abdomen needs attention by a veterinarian in case of possible egg retention. Swollen joints are most likely an indication of uric acid deposits, a condition called articular gout. Chameleons with poor perching ability and/or abnormal leg angles likely have metabolic bone disease. Swellings of the tissue around the eyes is common and needs proper treatment, possibly surgery, to correct.

  • Cherry eye is a common name for a prolapsed third eyelid gland. The gland is mainly responsible for tear production in the eye, and treatment is recommended to prevent long-term damage. Treatment involves surgical replacement of the gland, though some dogs will have a recurrence of the problem.

  • Chinchillas are generally hardy animals but can have several unique problems; understanding them will help you care for your pet and manage potential health problems.

  • Chlamydiosis (psittacosis, parrot fever, ornithosis) is a common disease of birds caused by a bacterial organism called Chlamydia psittaci. Birds with chlamydiosis exhibit a decreased appetite, weight loss, lethargy, diarrhea, nasal or ocular discharge, a fluffed-up appearance, and breathing difficulties. Testing and treatment are discussed. Chlamydiosis is a zoonotic disease, meaning that it can be passed to humans, so all new pet birds should be tested for this disease.

  • Chronic bronchitis (also known as chronic obstructive pulmonary disease or COPD) is a slowly progressing inflammatory condition of the lower airways. The most common sign is a chronic dry cough. The diagnosis, treatment, and prognosis are outlined in this handout.
