26. Weimaraner

Developed in the 19th century as a hunting dog, Weimaraners are large dogs used by royalty for stalking boar, bear, and deer. These dogs are very energetic and possess a great deal of stamina, eager to play and engage in games with their owners whenever possible. Their strong hunting instinct, despite them being a very obedient breed, make them a little bit more challenging to train in order to make them calmer and more behaved.
