Chihuahuas can form very strong bonds with one person and they become very protective.
My daughter had one that wasnt afraid of man nor beast.
Twas a female and it was very quick on its feet.

Big dogs went after it and it would evade them and reverse the situation.
Insteadvof being bit on the @$$ it would be biting the other on the @$$
