pedro the person crox listed is frank, he live's up my way and is a great guy to deal with, plus his price's are more than fair for new york. personally i would order the dog from another state. dog in ny = 300% mark up
Boxers are great dogs, but have you looked at any American Bulldogs? They have the same great personality and attitude with people and children, but in my opinion are smarter and more easily trained then Boxers. I may have offended some Boxer owners and do appoligize but this is just my experience with multiple dogs of both breeds. Here is a pic of my AmBully, 5 years old just ove 100lbs. I know a breader up here in CT if you are interested.
I used to have one show dog pure breed Boxer (won a few show contest) . They are a delight extremly friendly. But dont' expect them to guard your home or anything similar, they will want to play with the burgler more then bite him. Mines don't even bark at strangers.
