Cobalamin (Vitamin B12) Deficiency
Cobalamin deficiency is common in Norwegian Lundehunds, often secondary to gastrointestinal disease, and can lead to anemia and neurological symptoms.
Detailed Description
Cobalamin deficiency in Lundehunds is typically due to impaired absorption in the small intestine, often as a result of chronic intestinal disease. Cobalamin is essential for red blood cell formation and neurological function. Deficiency can exacerbate gastrointestinal symptoms and cause lethargy, weakness, and, in severe cases, neurological deficits.
