22. Dogo Argentino

Impressive in its size and gait, the Dogo Argentino makes its presence known in stature alone. This dynamic dog requires a lot of outdoor exercises and an owner who is willing to take charge. Because of its forceful stance, the Dogo can look very intimidating, making it a very good guard dog. Again, because it is so excitable, it can also become quite combative towards fellow canines or even other animals.  Unfortunately for this type of dog, it was mainly bred in Argentina to be used for big-game hunting, and because of this, it is illegal to own one in the UK.

23. Basenji

Originating from central Africa, the Basenji is a majorly active dog that will keep its owner on its feet. They are also known for their non-ability to bark, but yet they can whine, growl, chortle and even scream. Due to their high energy level, when left alone, they are known to destroy everything in sight, plus they can be very threatening towards other dogs, and especially suspicious toward strangers.  On the positive side, they are amazing watchdogs.
