An unplanned weight loss of more than 10% of a dog’s body weight is considered abnormal. Weight loss occurs because calories absorbed from the diet do not meet the calories being used by the body. This can occur due to many factors including excessive cold or physical activity, disease states that heighten the metabolic rate, insufficient calories or poor diet, inability to ingest the diet, inability to digest and/or absorb the nutrients in the diet, and loss of nutrients from vomiting, diarrhea, or polyuria. As well as a thorough history and physical exam, testing such as bloodwork, urinalysis, and imaging may be needed to determine the underlying cause in order to institute targeted treatment.
The simple description of an abscess is a pocket of pus located somewhere in the body. A cat with an abscess will often have a fever, even if the abscess has ruptured and drained to the outside of the body. Appropriate antibiotic therapy is a critical component of the successful treatment of abscesses, no matter the location.
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. In some cases, acne may be associated with underlying skin conditions. There are a variety of treatments that may be used for the treatment of canine acne.
Acute caudal myopathy results from overuse of the tail, causing a strain or sprain of the muscle groups used for tail wagging. Possible scenarios leading to limber tail include hard/vigorous play within the previous 24 hours, prolonged swimming, or active hunting within the past few days. The tail may droop limply between your dog's rear legs, or it may stick straight out behind him for a short distance before drooping. Uncomplicated acute caudal myopathy is treated with rest and anti-inflammatory medication.
Acute hemorrhagic gastroenteritis (AHDS) (also known as hemorrhagic gastroenteritis [HGE]), is an acute disorder of dogs characterized by vomiting and bloody diarrhea. AHDS can affect any breed, age, size, or gender of dog, but it is most common in small- and toy-breed dogs. The exact cause of AHDS remains unknown. An elevated hematocrit in combination with a low or normal total protein is an important clue that a dog may have AHDS. Intravenous fluid therapy with potassium and electrolyte supplementation provides the foundation of AHDS therapy. Dogs with AHDS may die, if left untreated.
Acute renal failure (ARF) or acute kidney failure refers to the sudden failure of the kidneys to perform normal filtration duties. ARF 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. The initial prognosis is guarded for all cases of ARF. If the cause is an infection, there is a better prognosis than if the cause is a toxic substance.
Acute respiratory distress syndrome (ARDS) is a life-threatening complication of critical illness. These underlying critical illnesses may include sepsis, pancreatitis, pneumonia (either due to an infection or the inhalation of foreign materials), trauma, near-drowning, and other severe illnesses. In ARDS, massive inflammation and the release of various inflammatory chemicals leads to the leaking of capillaries within the lungs. Signs of ARDS include increased respiratory rate, blue discoloration to skin and mucous membranes due to poor oxygen delivery, and occasionally coughing. Treatment of ARDS is primarily focused on supportive care and addressing the underlying critical illness.

Addison's disease is the common name for hypoadrenocorticism, caused by decreased hormone production from the outer part or cortex of the adrenal gland.
Hypoadrenocorticism, also known as Addison’s disease, is a condition in which the adrenal glands do not produce enough glucocorticoids (steroids) to allow normal body function. This condition is considered rare in cats, but numerous cases have been reported. Affected cats often have a history of waxing and waning periods of lethargy, decreased appetite, and weight loss. Long-term, cats with hypoadrenocorticism require medications to supplement the substances released from the adrenal glands.
