Are you a dog trainer, behaviourist or whisperer?

My partners dog is a breed he is unsure of. His sister got it for free as it was abandoned by a dog trainer.
It was sold as a XL bully.
But from the photo I cant say she is, the traditional looking kind.
Anyways she was in 3 different homes before reaching them.
Has displayed aggressive/fearful behaviour.
Almost bitten a few people and just generally reactive to nearly everything.
They've had her a year and in the year she has adjusted to the home and no longer barks at everything, but when she goes out, she is incredibly reactive to other dogs. She doesn't allow dogs to greet her, she makes this high pitched squealing, gets herself so frantic that her saliva turns frothy.


Because she is such a strong dog, I could never walk her. Her lead is a chained one. And my partner tends to walk her. The sister has lost interest and given up on her.

As there was a plan for me to move in to my partners place during my maternity leave, we decided to finally get the dogs to meet.
I had hoped she would have been spayed by now but he claims to have been struggling to get an appointment at his local vets... (I think he's been delaying why I don't know)
This past Sunday we introduced them in an open space. She was wailing and howling, and getting very worked up.
My dog just the friendly curious boy he is slowly approached her.
But the closer she got the more she started to snarl.
Just as I was about to pull him back she lunged forward to bite him.
Thank goodness she didn't get him.

We walked with them on opposite sides of the road and tried to just get her used to being on the presence of another dog.

Her behaviour made my dog quite frustrated and he started jumping up and wanting to go after her.
I had him in his training lead and a collar rope lead to give me the most amount of leverage so I wouldn't have to restrain him too much.
This seemed to annoy him more.
He turn to try and chew through the lead. But I was able to calm him enough to stop.
We walked, but her wailing then started making him mimic the same sound.

He doesn't really bark or make noises not unless he's alerting me to something or defending himself.

We got to a point where there was a good distance between them so I tied one of his leads to the bike loops opposite.
My partner and his mum stood with their dog across from us.

Again she started and was no longer listening to his commands.

Long story short we were able to get them maybe 5 paces apart. But he had to really hold her to get her to settle.
But her energy was still very aggressive. I made the stupid mistake or reaching out to her because she was watching me stroke my dog. But she went to bite me.

3 hours in total.
I concluded that I was happy to help if I could but he has to get a trainer involved because it was quite distressing to my dog.
Even though he was sat higher up on a step and being calm she was staring him out.
He basically just stopped looking at her and gave the signal that he had, had enough.


On the way home he was quite jumpy and his stools were very loose.

It's not a situation I would like to put him in again, knowing that she's like this I would never feel comfortable leaving them alone together and I definitely wouldn't want to be in the house with her and my baby.
Bruno has been really good with newborn babies, puppies and young children.

Always supervised but I don't feel like the way I did with her, with him.
I have stayed over and I sensed that perhaps she doesn't get enough attention. Seeing Bruno or baby get attention might trigger her.

She is dangerous!
