Does anyone know the average growth of a male dalmatian at 18 weeks? Today, we measured Oscar, and he is 16 inches at the shoulder and about 21-22 at the head. Is this big for a Dalmatian of his age, or is it average? We think he may grow to be about 24 inches at the shoulder if he continues to grow at the rate he is. He may be an above-average-sized Dalmatian. Thank you.
