How much should a Rat Terrier eat?

An adult Rat Terrier typically requires 1/2 to 1 cup of high-quality dry food daily, split into two meals. They may benefit from small-breed specific formulas to aid weight management and dental health. Because they are prone to obesity, avoid free-feeding and monitor their intake closely. Precise portions depend on their weight, age, and activity level to maintain a lean build.
