Black labs and chocolate labs shed just as much as yellows from my experience. I have only owned a yellow, but have spent time with blacks and chocolates at the shelter I work at and the lab rescue group I volunteer with. If shedding is a huge concern, I would not get a lab.

When anyone asks this question, I always have to remain loyal to my Reece baby and say POODLES ALL THE WAY!!!

Don't get me wrong, I love labs and would recommend them to any qualified dog person, BUT just since you said shedding was an issue.
