Thanks for the explanation on BOX and the information on Labs and shedding.
We had a Chocolate and her coat was as you described, compared to most blacks I’ve come across. However, she was a shedding machine 12 months of the year. That never bothered me at all but then I don’t vacuum often. The person who does was not amused.
He's not amused, but he's not amused at having to vacuum anyway, so it's hard to tell!
