Hi,
I've got a question or smth like that
My whippet is as good as gold with people and kind dogs, but when he meets a bullie ( dog ) he gives it to it like he'd be a pitbull, is it normal for this breed ?

I don't think its normal for the breed my whippets are show dogs and are used to seeing all sorts of dogs at the shows.

Maybe he senses something with these type of dogs that puts him on his guard or maybe he's picking up vibes from you and defending you.Don't have any other ideas just trying to think what might caause it if he's ok with other breeds

He doesn't care about breeds like, he'd play and look after a peacfull dog, but once he see an agresive dog with a wrong attitude he gives it to him no matter what

In that case he's having a go as he picks up the bad vibes of the attitude dog
