There have pretty much always been white markings showing up in Labs. Bolo spots are on the bottom of the feet, not uncommon and not considered anything to get upset about, do a search on Bolo if you want to find the source and reason for the name. A small amount of white on the chest isn't an automatic DQ even in the ring. Some people are particular about any white at all on their Lab, others don't really care, but white has always popped up here and there, nothing new about that.Oh no... now we're going to have a generation or two of super hunting & gun dog/FT/HT dogs that are sporting white spots. The conformation people will have even more to scream at us about. Love it.
