dont get me wrong i just gave examples that dont make a breed less breed, not that they should be bred, of course not, spay/neuter, but with color as in shepherds it took a while to get them accepted, they where present but not suitable for show and maybe silver labs will get their place as they had before as a variation of "chocolates", and as cali mentioned beauty contest..... in humans it doesnt mean we "need" to look like them, it just a "standard" for "beauty" that some people made and try to keep that way, that doesnt mean other people who are different are not pretty or human......
