I think you’re misinterpreting, I meant dogs of different breeds bring chill with an unknown dog of their own breed, while trying to get rid of dogs of a completely different breed, even if those have lived in the same neighbourhood for years.
Horses of different breeds in the same stable still have a hard time trusting each other, but not with one of their own breed, even if that’s a visitor.
And so forth.
TL;DR humans aren’t the only racist animals

Okay in all seriousness, this kind of comment is not helping the asker at all.
