I always thought liver roan was a common colour in working cockers which is why I chose blue roan as I wanted something a bit different although I should have gone home with a darling liver roan bitch that really tried so hard to come with me
....
I think choccy or chocolate is more a term of endearment a bit like w***er (the taboo word we are not allowed to use)
plus as it's become a trendy term unscrupulous breeders may be breeding just for colour, but I feel breeders would latch on to the popularity of the colour whether it be called liver or chocolate ... personally I tend to call them liver as I'm not that trendy.... unless it's a dog I know or owned and then I probably would as a term of endearment call it a cute little choccy, cos I'm soppy like that ....
