Boxers are medium, well-balanced dogs that feature a square frame. With short backs and strong limbs, these dogs are sturdy and thickly muscled. This breed is often seen with docked tails at the end of their short, tight-fitting coats. They are attentive, energetic and devoted to their masters. Boxers play well with children as they are gentle and patient as well as active and curious. With high levels of intelligence, they are quick and eager to learn yet can be sneaky or stubborn at times. They behave well with other household animals but are not immediately trusting toward strange pets or people. This instinct makes Boxers good guard dogs. They are a breed that combines agility and strength with style and elegance.
