Boxer's Behaviour

Recommended for: Family pets, guard dog, companion dog

Playful yet patient and generally well-behaved. Though the dogs mature late, they can be trained. After all, the breed still provides guide dogs to the blind.
Remember that breed only provides a general clue as to any individual dog's actual behaviour. Make sure to get to know dogs well before bringing them into your home.
