Boxer or Bandogge?

Hi, we have 2 “Boxer” dogs that are 22 months old. We were told they are Boxer when we rescued them from going to the pound at 1 month old. We have never seen the parents but know someone who has and have been assured they are Boxer but I have always wondered but never cared enough to look into it. One (Sadie) has a much longer nose than her sister (Sophie) so I was doing a little research and came across the Bandogge breed….I have never heard of it. Now I am wondering if that is what they might be. Sophie is 85 lbs and Sadie is 76. They are big babies. I will post a picture if someone can tell me how. I’d really to know. Thanks
