They don't read body language, they can smell fear and anger and if that person makes eye contact they will go for them.A Doberman Pincher I co-owned was so smart, she could read body language without being taught to do it.
She saved me from being robbed of several oz of weed once, she just jumped at the guy barking & spit was flying all over the place, she was on attack & wasn't playing.
The wanna be bad man ran into his car shouting for me to call the dog off, if I didn't keep her on a short lead she would have taken his throat out, turns out the cunt had a knife & when his hand went into his pocket he was gonna rob me. Somehow the dog "knew" & went to bite his face off to protect me, she didn't think about her own doggo safety it was automatic to save me at her own cost.
You tell me of a human who would do that?
You know all those times your doggo didn’t get along with someone you were friends with?
My previous malinois would growl at the corrupt cunt of a beat copper..nuff said...that dog was brilliant with 30 screaming excited kids around them he wouldn't bat an eyelid yet if if that cunt of a beat copper moved one foot forward he would rip him to shreds.
