Hey, I like this topic!
I've had Kelsey (@Rainbow Bridge), a mostly black Lab(with some GSD). Kelsey means 'of the water' or something close to that. I wanted a water related name for a Lab.
I now have Bailey, a chocolate Lab. Bailey, for Bailey's Irish Cream. She's a very dark chocolate color, I should have named her Oreo
I also have Heidi, a black Lab, large for a female. (To me Heidi sounds like it should be a petite yellow Lab.) I had asked the breeder for a yellow Lab female, I had a really unique name all picked out. There was only 1 yellow, but 5 black females. The breeder kept the yellow one for herself, so I got a black one. But I had no idea what to name a black one. I ran a whole bunch of names past the whole family, and no one could agree to one of them. Finally, in desperation, I said,'How about Heidi?' 'Yes, we like that' everone said. I said 'Her name is Heidi, and we're not changing it!' (...now had I known her registered name would be "The Dance", I would have named her Dancer, it would have suited her better )
