Please, please keep her calm and do NOT let her burn around the yard!!! We kept Maggie as calm as we could but her stitches burst late one night. We had to rush her to emergency for an operation - I have never been so scared or worried. If you search the forum you should be able to find my posting documenting the details.
Try new things to chew on - both toys and food. New experiences - musical instruments. Try taking her to Petsmart to look at the birds, fish, etc. Spend some time grooming her. Practice new commands. Anything to keep her mind occupied while not doing anything physical.
Good luck - it is extremely difficult to keep a boxer quiet!!
