Boxer temperament, personality, training, behavior, pros and cons, advice, and information, by Michele Welton, Dog Trainer, Behavioral Consultant, Author of 15 Dog Books
Boxers can be fine family dogs if you can proviide enough exercise and training to control their rambunctiousness when young, and if you can provide for their special needs due to their unnaturally short face.
As puppies and young adults, Boxers are animated, playful (often cuckoo!) dogs who love to romp and jump. Middle-aged Boxers typically become more deliberate and dignified and make calm, loyal companions for the rest of their (unfortuntately not very long) lives.
Exercise needs vary from long daily walks for more sedentary Boxers to vigorous daily romping for high-energy individuals – but not in hot weather, because Boxers are more susceptible to heatstroke than most dog breeds.
