#7 This breed of dog has excellent hunting qualities, which allows it to be actively used by hunters.
#8 The disadvantages include their increased energy and ingenuity in tricks.
#9 Without an active pastime, out of boredom, they can misbehave at home, ruin things.
It takes a lot of time for walks, as well as an invention to keep the dog in a fenced area or to keep it on a leash, otherwise, the dog, obeying the hunting instincts, can hit the chase at any minute.
