I am confident that if you have the right treat (LOL) you will do great. No serious basenjis are fun to train IMO I just finished my first class with my boy in the middle of May and he'll be 2yrs old at the end of this month and he did great and he LOVED going to school every week (he's a brindle beastie too ;)) We had dogs of all sizes and ages in our class.
I'm sure your Otis will do just great; look at it this was - the yappy dogs are really a great training tool for you as a added distraction. Your commitment is what matters most, make sure you do your "homework" and pratice in place other than your living room, go to your front yard, back yard, garage, pet store, pet store parking lot.
And the biggest thing with basenjis is change up the routine and KEEP IT FUN or they will get bored. Basically if you have several things for homework do like 5-7 practice of "sit" then move on to something else like "walk easy"
