The Boxer was developed in Germany from bull-baiting stock and was used extensively for police and military work. Their ancestry includes English Bulldogs, Mastiffs and various terriers. The boxer dog is a strong breed, with a compact and stocky frame full of power with dark eyes and nose with large nostrils for increased air intake. This dog breed was much more domineering and tough before it was bred out of them, as they were crossed with the Bulldog and Mastiff. German boxers and American Boxers have distinct shapes of their heads, as the German is much larger than their American counterparts.
The Boxer makes a great pet for an active family. Both boxer puppies and adults love to play with children and other dogs, and dislike being alone. They are naturally protective of home and family. Like most working dogs, the Boxer requires a good amount of mental and physical exercise daily to keep them out of trouble. Because they are so intelligent and curious, if they are not trained well the boxer will wreak havoc on your home and probably chew all your shoes. They are not being malicious, it is just a sign of boredom.Boxer puppies and adults are extremely playful, and it is not uncommon to see them try to grab you with their paws and play-bite as well as roll over on their backs for a good belly rub. They are very communicative, so if your boxer is hungry or thirsty you'll know about it relatively quickly with their body language. The same applies for if they have to go outside and go potty. Because the boxer is good with communication and smart, they are quick learners as puppies and easily trained. You should make sure to teach your boxer puppy not to jump around a lot, as they love to do so on furniture and visitors to your home.
Their short close-lying coat is easy to care for, all they need is weekly brushing and the occasional bath. Boxers are sensitive to hot weather because of their shortened muzzle, care should be taken that they do not overheat. You should also be sure to check your boxer's heart with regular vet trips, as they are known for problems with their aorta and heart rhythms.
