Can dogs be racist against people?

We are told that there is no such thing as race and so it follows that there is no such thing as racism.

I do not think so.

Serious reply, no bullshit

I suspect that dogs can be racist

I had a small 60 pound female Pit Bull, pure muscle and rage, meanest goddam dog you ever saw, she tore skunks to pieces twice in my garden in Yonkers, she fought a gigantic Mastiff to a bloody standstill and she was especially violent towards black people
She lunged at my Mailman so many times I had to keep her on the other side of the yard or he wouldn't deliver the mail (he was a black dude but not the only black dude this dog wanted a piece of)

This is NO lie

My Vet told me she was likely a 'target dog,' the Bloods and Crips and Latin Kings were all heavily involved in that disgusting dog-fighting game back then and given her sex, size and location where she was rescued she was probably a frequent punching bag for prized dogs and was possibly used as a breeder too

Some people are just scum

She was a fine girl, she had about 10 good years in my grassy yard and cozy home before she fell ill and died

RIP Whitey😘

Yes. I had a cousin who got a German shepherd, and he went nuts every time he saw black people, so the police obviously train them.

There was a movie about this subject: White Dog (1982): https://en.wikipedia.org/wiki/White_Dog

EDIT: samoanjoes' IMDb link above is about this movie.

FACT: NO!!!!!!!!!!!!! Prove me wrong.

Yes! My friend has a Japanese akita who is so gentle and loving. But their old next door neighbours when she was a puppy were Asian (middle eastern) and kept throwing rocks at her and jabbing her with sticks through the fence. She does not like brown people, and especially children now as a result.

Unfortunately, you can't explain to animals that people are different. She just associates small brown humans with pain.
