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.

Chediak-Higashi Syndrome is a rare genetic disease of smoke-blue Persian cats. The condition affects how the body processes waste products, resulting in changes within the body’s cells and leading to abnormal pigmentation of the skin and coat. The condition can lead to eye abnormalities and problems with blood clotting, but most cats can have a normal lifespan with careful health monitoring.

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.

Chin acne in cats is a poorly understood disorder of follicular keratinization (the overproduction of keratin, a protein found in the outer layer of skin). If this excess keratin is trapped in the hair follicle, comedones (blackheads) form. Pustules (pimples) may form if bacteria infect the comedones. The underlying causes are not fully understood but may be associated with excess sebum production, viral infection, immunosuppression, stress, or poor grooming. Treatment options are available and often involve improved hygiene.

Chlamydial conjunctivitis in cats is highly contagious and can look similar to herpes conjunctivitis. Young cats and kittens are especially vulnerable to this infection, although chlamydia can be detected in cats of all ages. It is one of the most common causes of infectious conjunctivitis in cats. This handout describes the clinical signs and how this condition can be treated or prevented.

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.

Cholangitis/cholangiohepatitis in cats refers to inflammation of the bile duct or a combination of inflammation of the bile duct, gallbladder, and surrounding liver tissue. The clinical signs, diagnosis, treatments, and prognosis of the conditions are outlined in this handout.
