I get what a zipper is and a cowlick but does the "squiggly" line down Skye's back have a name? Her sister had one too, if that matters. Is it a good, bad or indifferent thing in regards to markings? Our male (who is from a different breeder) doesn't have one. I can attach a picture if need be.
That'd be a wavy coat, not sure there is a name for it though, other then just that, a wave!
