If you are really interested in getting any dog and someone is allergic, really do your research. But just to give more background on the Boxer. I posted pictures of my Boxer Nico in the Thread we had for Pets recently. My daughter is allergic to dogs and amazingly, she is not allergic to Nico. We have had poodles, Miniature Schnauzers, Yorkies, Yorkie-Poo, and she was allergic to all of them except for Nico and she's 11. But we kept trying because we love animals and she has begged for another Dog for years. I was very hesitant as well, but gave it a try. We lucked out and got a "DRY MOUTH" boxer. My Boxer does not drool and is AKC registered, full blood Boxer. Not All Boxers have the extremely wet, drooling mouths. My Boxer is an indoor dog, with access to the backyard thru a doggie door, but we keep him extremely clean with professional grooming twice a month to help with his coat shedding to help with any allergie concerns that may arise. So far, we haven't had any, and Nico turned 2 in May.
A wonderful website is Boxerworld.com. Take a look before discounting them totally, but do research on all dogs before making a final decision. Hope this helps.
