I do not have puppies or adults available at this time.
Another option is rescue. There are many older boxers out there looking for their forever family. There are several advantages to a rescue. Usually they are already housebroke, through most of their destructive chewing stages and might have some obedience already started. Rescues also seem to bond more because they know they are special and being given a second chance.
Here is a link for rescues through the AKC website. It list the rescues by breed and then states.
Good luck with your future family member.
