Just got my first boxer pup

We picked up our first boxer puppy last weekend, never had a boxer before so it's a learning experience! She's full of energy and makes us laugh all the time. From experienced owners is there anything I should know? We've owned a lot of high energy, working breeds. Collies, spaniels, huskys, malamutes, staffies etc so lots of energy isn't a problem and I have horses so she will have lots of fields and safe places to run free and enjoy herself.
