My SIL's dog is liver and white - to completely and utterly honest it's my least favourite colour for a worker simply because they spend their lives being mistaken for a springer. It's not that they're unattractive - far from it.
Her coat is much easier to manage than Jarv's solid liver coat which is a nightmare to be frank (because it is fine and quite springer like
)
here she is
- same sire as Jarvis
and here she is with her litter mate (the shaved liver roan) and Jarvis.
as for bitch or male that's completely up to you - I think you need to work with some before you decide on a working cocker to be honest as the drive between a working cocker and a show cocker can be quite dramatic.
