Boxers are athletic, energetic, happy dogs. Their short muzzles and large underbites, along with their proportionately long tongues, give them a distinctive appearance. Originally bred in Germany, these dogs are now hugely popular family dogs, as they adore children and other animals and love to be with their owners. Boxers are clever and quick to learn. They have a lot of energy and do best when they are given something to occupy them, whether it be obedience, agility, or any other kind of mental challenge. Boxers are medium-large dogs, typically weighing in at around 55-65 lbs.
