Canine acne is an inflammatory disorder of the lips and the skin of the muzzle. Dogs with mild cases of acne often have red bumps or pustules (pimples) on their skin, which can, in more severe cases, lead to generalized swelling of the lips and muzzle, bleeding wounds, or scabs on the face.

Acute kidney injury (AKI), previously referred to as acute renal failure, is the sudden failure of the kidneys to perform normal filtration duties. AKI leads to accumulation of toxins and other metabolic wastes in the bloodstream, dehydration, electrolyte imbalances, and disturbances in the acid-base balance of the blood. AKI is potentially reversible if diagnosed early and treated aggressively.

Acute respiratory distress syndrome (ARDS), also known as shock lung, is a life-threatening complication of critical illness in dogs, such as systemic infection, systemic disease, severe trauma, or near-drowning. Treatment involves targeting the underlying cause while supporting the dog's compromised lung.

Anticoagulant rodenticide is used to kill mice, rats, and other pests. Poisoning occurs when a dog ingests rodenticide accidentally. Anticoagulant rodenticides cause excessive bleeding by interfering with vitamin K1 recycling in the body. Vitamin K1 is needed for the body to make certain clotting factors that enable blood to clot and help control bleeding.

Baylisascaris procyonis, also known as the raccoon roundworm, is a parasite found in the intestinal tract of many raccoons. In some cases, this parasite may also spread to dogs and, less commonly, cats. Infection in dogs often results in no symptoms, but it can result in diarrhea. In rare cases, migration of parasite into the dog’s nervous system can result in encephalitis (brain inflammation), and death. Baylisascaris procyonis can also rarely infect humans.

Botulism is a rare condition that causes paralysis in dogs. Dogs are exposed to botulism by eating raw meat or dead animals containing botulinum toxin produced by Clostridium botulinum. Signs, diagnosis, and treatment are discussed.

Bowel incontinence is the loss of the ability to control bowel movements. There are two broad causes of fecal incontinence: reservoir incontinence and sphincter incontinence. In reservoir incontinence, intestinal disease interferes with the rectum's ability to store normal volumes of feces. In sphincter incontinence, a structural or neurologic lesion prevents the anal sphincter from closing normally. Clinical signs, diagnostic testing, and treatment vary based on the underlying cause.

A burn is a type of skin injury, commonly caused by heat, fire, or chemicals. Burns are classified based on how many layers of skin are affected; this classification scheme can help predict prognosis. Treatment of burns varies, depending on the severity of the burn and how much of the body is affected. Superficial burns may heal without treatment, while more severe burns may require hospitalization and possible skin grafts.

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.
