15. Basenji
Basenjis are classified as sighthounds. They originate from Central Africa. This hunting breed is known for its alertness, curiosity, and affection. This breed is reserved with strangers and widely regarded as the second-least trainable breed type. Say “as obstinate as a mule” is no more. Instead, say “as obstinate as a basenji”.
16. Gull Dong
The gull dog, a cross between the Gull Terrier (a breed of the Gull Terrier) and the Bully Kutta (a mix of the Bully Kutta and the Bully Terrier), is strong and powerful to the point that it’s hard to believe. It was bred to be a fighting breed. The aggressiveness of this breed is legendary. You can’t control it with your limited knowledge of dog training.
