These two conditions are the result of calcium being deposited within the skin. They are usually of minor significance in young dogs and cats but can indicate serious underlying diseases in older pets. This handout describes the different types of calcinosis circumscripta and cutis and associated causes, clinical signs, and treatments.

Calcium oxalate bladder stones are composed of a mineral called calcium oxalate. Cats are more likely to develop oxalate stones when their urine contains high levels of calcium and oxalate. Additionally, a low urine pH promotes the formation of oxalate stones. Bladder stones can cause significant inflammation and irritation of the bladder wall. Signs may include frequent urination, straining to urinate, blood in the urine, and urinating outside of the litterbox. Male cats especially are at risk of a life-threatening urinary obstruction. Treatment options and prognosis are discussed.

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.

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.

Cardiomyopathy is a term used to describe diseases of the heart muscle. In cats, three classes of cardiomyopathy have been described: hypertrophic, dilated, and intermediate or restrictive cardiomyopathy. In the early stages of disease, the cat may not show any signs. Heart disease can be suspected based on clinical signs, chest X-rays, and electrocardiography (ECG). The long-term prognosis for a cat with cardiomyopathy is variable, and depends on the cause of disease.

Carpal hyperextension is an abnormality of the carpus (wrist) that causes increased extension of the joint. Carpal hyperextension in cats is typically caused by trauma. Cats can also develop carpal hyperextension in association with other systemic diseases (e.g., inflammatory arthritis, diabetes mellitus, electrolyte abnormalities). Cats with carpal hyperextension have a noticeable bend at the wrist, forcing their foot 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 cats with carpal hyperextension may also have abnormalities in other joints. X-rays and other additional tests may be recommended. Treatment of carpal hyperextension depends upon the severity of the condition and may involve surgery.

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.
