Welcome to the forum!
I also have mild allergies to dogs but I have not had any problem with our two B's. The only reason we stumbled upon basenjis was that we were looking at a hypoallergenic breed list. Looking back I'm so happy we did!! I haven't had many allergy issues with them, the worst being some skin issues with our pup's fur. I can handle that much better than itchy eyes, stuffy nose, sneezing, etc
Advise on living with a teen-B. Order is your friend, haha. Sense of humor is also necessary. As far as destruction goes, the best way to get around that is become a very tidy person if you're not already…..just an example of being trained by a basenji! Things I'm sure you've discovered in 5 months....
