Unless someone else can prove otherwise, they are watching for the American Tennis Ball Deer buck, because Does prefer Tennis Ball bucks! His name is “Dennis” (with your permission) because it rhymes with “tennis”.
English is written funny, isn’t it? “Does” like in “don’t” is spelled the same as “does” like in “female deer”, but they are not pronounced the same. Unless maybe you live somewhere selling duck calls or somewhere else that I haven’t been either.
