I have an incredibly aggressive rescue nothing seems to work. And ideas?

Our dog is somewhat aggressive on a leash, but is fine at the dog park. When she is being aggressive on a walk, I make her stop and I kneel down and hold her and talk to her. It seems to help a little. The pinch collar is what is truly helpful, though. I never walk her without it. That is how much of a difference it makes. Hopefully, it will have the same effect on your dog as well.

I used it in my boxer and it did wonders. I'm having a baby and scared that I might need to have my father take care of her if it's not fixed when she comes..

water with a sprinkle of vinegar..... apparently it works on her lol. Hate doing it but we will see if it solves the behavior

@Kimmyvivi Definetely shock collar then baby takes priority

@JRVanguard which is a painful thought. She's come so far.

But with the later option my dad is good and it's pain free.

@Youni19 I've tried clickers. Dog whistles, crate, and I'm at a loss.

You just need to try to distract her somehow, I suppose.. Try randomly rewarding her (with food, petting and playing) whenever she's calm during walks and especially if/when she's calm around other people/dogs.
For example, the moment you see other people coming, start distracting her, rewarding and petting her, telling her she's doing good and what not.
But the moment she starts to showing aggression, ignore her and try turning around and walking the other way with her (?)
@Kimmyvivi

I've not tried treats when she's not aggressive because it seems like she always is

@TheOneyouwerewarnedabout it's a girl so that'll be hard.
