9. Bull Terrier

Bull Terriers are unforgettable with their egg-shaped heads and robust builds. Once seen, they’re etched in memory. Loyal, lively, and affectionate, they make great companions. Bred initially for bull-baiting and later refined as pets, they’re now cherished family dogs. Their playful, clownish antics often delight their households. Despite a tough exterior, they’re gentle with kids when trained and socialized. Their stubborn streak demands early socialization and consistent, positive training to shape them into well-mannered adults.
