Boxer: Size, Weight & Temperament

The Boxer is playful, loyal, and highly people-oriented, often retaining a puppyish playfulness well into old age. He is patient with family members, including children, though he can be boisterous and prone to jumping and bumping. He is watchful toward strangers but rarely aggressive without cause.

This breed needs extensive daily exercise but cannot tolerate exertion in heat or high humidity because of his short muzzle. Boxers do well in dog sports such as protection sport, agility, or moderate weight-pulling. Breaks and shady spots should be planned for during activity.

The short coat is low-maintenance; occasional brushing is enough. Facial skin folds should be checked and cleaned regularly to prevent irritation. Because of the short nose, adequate cooling in summer must be ensured.

Breed-typical conditions include hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy (Boxer cardiomyopathy), and an increased tendency toward certain tumour types such as mast cell tumours. The brachycephalic build predisposes the breed to heat intolerance and breathing difficulty under exertion. Regular cardiac checks are recommended.
