Hi you can try calling the kennel club for a list of boxer breeders in the northwest
or take a look here http://www.ukboxerdogs.freeuk.com/ukfound.html
guest why dont you join then you can ask more questions and there are several boxer people on here to help and advice you if you have any questions..polly
forgot to add not being nosey but why do you want two boxer puppies. looking after one boxer puppy and training it is very daunting for a first time owner having two will be twice the work...
