yellow lab color change?

[tezr]

I was always under the impression that the first thing lost in the mix of a zebra and yellow lab was the black dorsal stripe. I am sure this cannot be the case 100% of the time.

interesting read.......

There are plenty of bad strains out there - some with lots of black on the body and face. There is a morph with a whitish belly that is not as attractive. Don't be mislead into thinking that is a man-made strain. This is a naturally occurring morph that comes from Lion's Cove, along side the yellow lab we all know.
