Has your wife been around the dog since it was a puppy? The corn chip smell is part of the beauty of the boxer! Their ears, feet, and sometimes just their fur kind of smells like fritos... or cheetos... but it's part of the allure in my opinion. If you just got the dog, and maybe she just hasn't got boxer fever yet... if she's an animal lover, she'll get the fever... sometimes it takes a while, but I think everyone gets it... don't they? I'm over at my mom's house right now, and there is no woman in the world more sensitive to smells, and who's NOT a dog lover than my mom... but guess who's chewing his chewy at my feet IN my mom's house?? My mom has the fever now and loves him....she has it bad!!!
Tough situation, but boxers are INSIDE dogs... how would your wife like sleeping in the tool shed?? They're like little people, and they need the same attention to a certian degree like toddlers do... you wouldn't make your toddler sleep in the shed would you??
