My 2-3 year old lab loves most people... Cept black people (seriously, she's better since my next door neighbor is black and comes over daily, she loves him now, but most black 'men' she hates, even after she meets them, she will still show aggression, she does seem ok after the initial greeting.) and theres an occasional growl at some white people, a friend brought his 6 year old kid over (half black)and my pup growled... I told her no and spanked her butt, but she still growled, kid wasnt doing anything cept wanting to pet her)

It seems most black males she doesnt like, and occasionally certain white people, she will bark and growl at, even when i bring them into the house, or she sees them walk by, doesnt matter, I really want to break her from this habit. What can I do besides look her in the eye, hold her beak and tell her no. (She doesnt look me in the eye when she knows she did somthing wrong, the shame!)

BTW: I found my pup about 8 months ago, but from what I was able to tell, was the person that used to own her was black, and she was skittish when you moved your hands. (She is much much better now that i've been her friend.)

So what can i do from breaking her growling at people?
