One of the more common uroliths in the dog is composed of calcium oxalate crystals. Current research indicates that acidic urine high in calcium, citrates, or oxalates predisposes a pet to developing calcium oxalate urinary crystals and stones. The most common signs that a dog has bladder stones are increased frequency of urination, painful urination, and blood in the urine. Male dogs are more commonly affected and may be at risk of a life-threatening urinary obstruction. Treatment options and prognosis are discussed.

Campylobacteriosis is a bacterial intestinal infection usually acquired by exposure to raw meat, poultry, or infected water, but can be spread between pets and humans. Signs of infection are watery or mucoid diarrhea with straining, possible cramping, lethargy, and fever. Testing, treatment and prevention are discussed.

Candida is a type of yeast that may cause problems in the digestive tract of birds. In young birds, immunocompromised birds, or birds that have been on antibiotics for an extended period, candida may overgrow in the digestive tract and cause various problems, such as 'sour crop'.

Canine coronavirus (CCoV) is not the same virus as SARS-CoV-2, which causes COVID-19. Canine coronavirus disease, known as CCoV, is a highly infectious intestinal infection in dogs, especially puppies. CCoV does not affect people, and causes gastrointestinal problems as opposed to respiratory disease. Crowding and unsanitary conditions lead to coronavirus transmission. This article discusses signs, treatment, and vaccines for this disease.

Kennel cough is the common name for an infectious respiratory disease that affects the trachea and lower airways in dogs. Viral or bacterial pathogens may cause it. Treatment may or may not be necessary with antibiotics and, in some cases, anti-inflammatory medication. There are no long-term effects from this infection.

Canine influenza is a relatively new, highly contagious virus that causes respiratory disease in dogs. It has been reported in all US states and some Canadian provinces. Clinical signs include coughing, runny nose, and fever. Definitive testing can be performed in the early stages of the disease. Vaccination is recommended for dogs at a higher risk of infection or morbidity. The virus is not spread to humans, but cats can become infected.

Canker is now rarely seen but is a serious infection of the horn of the foot, that results in the formation of a soft, moist, disintegrating growth of horn. It most commonly affects the hind feet and is most often seen in horses kept in wet tropical climates, or in large draught type horses.

Carpal hyperextension is an abnormality of the carpus that causes increased extension of the joint. There are many causes of carpal hyperextension: it can be caused by trauma; in young dogs it may be caused by a developmental abnormality; and in older dogs it may occur as a degenerative condition. Dogs with carpal hyperextension have a noticeable bend at the wrist, forcing their lower limb into an abnormally flattened position. If carpal hyperextension is caused by trauma, it may also be associated with pain and swelling. A tentative diagnosis of carpal hyperextension can be made based on initial observation, but a thorough physical examination is necessary because dogs with carpal hyperextension may also have abnormalities in other joints. Treatment of carpal hyperextension depends upon the cause and severity of the condition and can range from medical management to surgery.

Carpal laxity is a condition in which the carpus has an abnormal or excessive range of motion. Carpal laxity can show up in one of two ways: carpal hyperextension or carpal flexion. The underlying cause of carpal laxity has not been definitively determined but may be caused by nutritional factors (specifically excessive caloric intake and/or excessive calcium intake), genetic factors, and being raised on slippery flooring surfaces. Signs of carpal laxity may be seen at any time from 6 weeks of age onward, but the condition is most commonly noted between three and six months of age. Activity modification is often recommended for affected puppies by keeping them off slippery surfaces. Most puppies with carpal laxity will appear completely normal within six to eight weeks.

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.
