Conures are considered small- to medium-sized birds and are characterized by long slender bodies, long tapered tails, and large beaks. Tame conures can be very affectionate, social birds that demand a moderate amount of daily attention. Conures are not well known for their capacity to speak but often scream loudly. Some conures commonly kept as pets include the jenday conure, blue-crowned conure, nanday conure, mitred conure, sun conure, green-cheeked conure, and maroon-bellied conure. Young birds may be easier to tame and train than older, wild-caught, or colony- or parent-raised birds. New birds should be exposed early to different events to help them become calmer, more well-adjusted pets. After bringing your new bird home, you should have it examined by a veterinarian familiar with birds to help ensure that it is healthy. Like all other pet birds, conures require annual, routine veterinary health check-ups.

Corneal dystrophy is a term used to describe several conditions that occur in dogs and cause the corneas to become opaque. There are three major categories of corneal dystrophy: epithelial, stromal, and endothelial. Each is named by the anatomic location of the abnormal tissue and opacity.

The cornea is the transparent, shiny membrane that makes up the front of the eyeball. With a corneal ulcer, fluid is absorbed from the tears into the stroma, giving a cloudy appearance to the eye. The most common cause of a corneal ulcer is trauma. Less common causes of corneal ulcers include bacterial infections, viral infections, and other diseases.

Corns are specific types of bruises of the sole, specifically occurring at the angle of the sole between the hoof wall and the bars, i.e., at the 'seat of corn', most commonly affecting the medial (inside) aspect of the front feet.

Crop infections in birds are not as common as they once were, but are still a potentially dangerous condition in all avian species. A slowing or stoppage of crop motility can be caused by bacteria, yeast and a variety of viruses. Early veterinary attention is essential to help treat this condition.

Treatment for Cushing’s disease using mitotane involves two phases: initiating phase and maintenance phase. Monitoring your dog’s food and water intake is very important. This handout provides detailed treatment instructions for dogs prescribed mitotane. Follow your veterinarian’s instructions carefully and report changes in your dog’s behavior to your veterinarian.

Cutaneous histiocytosis is an uncommon condition in dogs. It is a non-cancerous increase in the number of reactive cells (histiocytes) caused by an immune system dysfunction. It generally manifests as multiple bumps and nodules confined to the dog's skin. The clinical signs, diagnosis, and treatment of this condition are explained in this handout.

Systemic lymphoma is a very common cancer in dogs, but the cutaneous form is quite rare. Current statistics suggest that cutaneous lymphoma accounts for only about 5% of canine lymphoma cases. The disease can present in a variety of lesions, including ulcers, nodules, red patches, and areas of hair loss and skin scaling. Because not very much is known about canine cutaneous lymphoma, there are no standard treatment protocols and the prognosis is poor.

Cutaneous papillomatosis is the development of papillomas (non-cancerous growths, or warts) caused by the papillomavirus and affects many pet birds. Commonly affected species are finches, canaries, cockatiels, budgerigars, and African grey parrots. The clinical signs and treatment for this condition are explained in this handout.

Cuterebra are botflies that spend the larvae stage of their lifecycle within rodent or rabbit hosts and can accidentally infect dogs. They enter through the nose, mouth or a skin wound. They usually develop a cyst under the skin that can be located as it enlarges and often a breathing hole can be seen. The larva (warble) will leave the dog when it is ready to form a pupa but it will often leave behind a secondary bacterial skin infection or abscess in the empty cyst. Rarely, the larva/cuterebra migrate aberrantly through the dog causing inflammation and damage to different tissues, including the brain and eyes, and even potentially cause a severe systemic inflammatory response. Treatment depends on what damage has been done and can include removal of the warble, debridement or removal of the cyst, antibiotics and symptomatic and supportive treatment of the results of aberrant migration. Prognosis is generally good if only the skin is involved. Cuterebra infection can not be prevented easily, so monitoring the dog regularly for signs is important.
