My boyfriend ruined his dog

Well at least it’s my opinion. He have this huge dog (mixed breed) and he have somehow managed to scare the dog from it was small so it thinks every insect is dangerous.

So now everytime our dog sees a butterfly, an ant, a bug, a fly whatever it panics and runs to him all shaking. And he just pets him and tells him he’s clever and stuff. Inside me it’s boiling, I’m so annoyed why he have done this to the dog and does nothing to make it better. Like if we are outside and we have to tie the dog somewhere and there is an ant, instead of trying to teach the dog it’s not dangerous he’s like “oh no we have to put him somewhere else”... so the dog will still think it’s dangerous 😂😂😂😂

Ffs I’m so annoyed. I’m maybe crazy but...,. Idk. I just had to went.
