The Boxer was bred from the English Bulldog and the now extinct Bullenbeisser and is part of the Molosser group.
What should you NOT feed your dog?
Chocolate, onion, garlic, grapes,
raisins, Macadamia nuts, bones, coffee, tea,
 soft drinks, beer, wine, alcohol, milk,
 and all other dairy products, raw fish, raw
eggs, salt, baking soda, baking powder, fatty foods,
and avocados.
Although the Boxer has a strong build
 and his heritage is linked to a warrior dog breed,
 essentially they are big dogs that act like energetic
 puppies. Therefore, you need to be ready for a dog that
 will love to jump up on people and furniture, and will
chew through just about anything. Thus, you will need to
provide your Boxer with proper obedience training, as this breed can
 be exceptionally stubborn when it comes to training.
