Cost drivers & health considerations for the Tosa
As a Giant breed, the Tosa eats more than average (7.8 cups/day), inflating food costs by $1,755 and requiring higher medication doses.
Food cost formula: The Tosa's food cost ($1,755/year) is derived from its average weight of 150 lb. Lighter breeds eat less, so food cost scales with body weight via the veterinary RER/MER metabolic formula—a transparent, breed-specific calculation used by veterinary nutritionists. This means the Tosa's food budget is unique to this breed's size and activity level.
