Hyperaldosteronism

Feline hyperaldosteronism, or Conn’s syndrome, is an endocrine disorder caused by excessive production of the hormone aldosterone by the adrenal glands, leading to severe potassium depletion and hypertension.

Hypocalcemia

Hypocalcemia is a critical medical condition characterized by abnormally low levels of calcium in the blood, impacting various bodily functions and requiring prompt veterinary attention.

Dogs & Cats
ChronicSevere

Portal Hypertension

Portal hypertension is a pathological increase in blood pressure within the portal venous system, typically secondary to structural liver disease, vascular anomalies, or obstruction of venous outflow.

Dogs & Cats
ChronicSevere

Hypercalcemia

Hypercalcemia is a condition characterized by abnormally elevated levels of calcium in the bloodstream, which can lead to systemic organ damage if left untreated.

Dogs & Cats
ChronicLife-Threatening

Hypoadrenocorticism

Hypoadrenocorticism, commonly known as Addison's disease, is a life-threatening endocrine disorder in dogs caused by the insufficient production of glucocorticoid and mineralocorticoid hormones by the adrenal glands.

Dogs
ChronicSevere

Glomerulonephritis

Glomerulonephritis is an immune-mediated inflammation of the kidney's filtering units, the glomeruli, leading to protein leakage and potential progressive renal dysfunction.

Dogs & Cats
ChronicModerate

Exocrine Pancreatic Insufficiency

Exocrine Pancreatic Insufficiency (EPI) is a chronic digestive condition where the pancreas fails to produce sufficient enzymes, preventing the body from properly breaking down and absorbing nutrients from food.

Dogs
ChronicSevere

Renal Amyloidosis

Renal amyloidosis is a progressive, irreversible condition characterized by the extracellular deposition of insoluble fibrillar proteins within the kidney, leading to nephrotic syndrome and chronic renal failure.

Dogs & Cats
ChronicModerate

Hyperadrenocorticism

Hyperadrenocorticism, commonly known as Cushing's disease, is a chronic endocrine condition characterized by the overproduction of cortisol by the adrenal glands.

Dogs
ChronicLife-Threatening

Pheochromocytoma

Pheochromocytoma is a rare tumor of the adrenal gland in dogs that produces excess adrenaline, leading to a variety of serious health issues.

Dogs
ChronicModerate

Fanconi Syndrome

Fanconi Syndrome is a chronic, often progressive disorder of the canine proximal renal tubules that leads to the excessive loss of essential electrolytes, glucose, and amino acids in the urine.

Dogs
ChronicLife-Threatening

Hepatic Encephalopathy

Hepatic encephalopathy is a complex neurological syndrome resulting from severe liver dysfunction or portosystemic shunting, which causes toxic metabolites to reach the brain.

Dogs & Cats
ChronicModerate

Diabetes Insipidus

Diabetes insipidus is a rare hormonal disorder characterized by the body's inability to concentrate urine, leading to extreme thirst and excessive urination.

Dogs & Cats
ChronicLife-Threatening

Gallbladder Mucocele

Gallbladder mucocele is a life-threatening condition in dogs characterized by the accumulation of excessive, thick, inspissated mucus within the gallbladder, leading to bile duct obstruction or rupture.

Dogs
ChronicModerate

Fibrosing Liver Disease

Fibrosing liver disease in dogs is a chronic, progressive condition characterized by the excessive accumulation of fibrous connective tissue within the liver parenchyma, leading to impaired hepatic function and potential organ failure.

Dogs
