Bless you snowflake, i feel your pain, we was in the exact same situation with our Bully a couple of years ago, it totally broke my heart to rehome him and took a year of me fostering my own dog as i didn't want him put in kennels while a rehoming center helped find him a new forever home, i went though the center as i really wanted any new owners he has to be vetted properly and they did all that alot better than i could have ever done,
our reasons for rehoming where also similar to yours my Bully was totally awful to my gentle rottweiler who is very well behaved his a grand old gent and you could see that my bully would intimidate him so badly , give them both a bone each and even if bully was in the garden and rottie in the house my rottie would not touch his bone, it was sad to watch,
they also had a couple of fights as he would walk past my rottie and for no reason bite him in the face it was really horrible , one fight where we was woken up in the middle of the night to them fighting downstairs and we rushed out of bed down the stairs and my partner fell and broke his arm in the process while trying to separate them , it got to the point where every time i heard a growl my heart would sink it really had me living on my nerves, it was an awful time,
i then used a crate for a while but again not the answer even tho bully liked it as his space and bed area to a point but when we went out he had to be crated all of this just led to him being miserable and developing a skin condition which i put down to stress,
i finally went to this rehoming center for help and a year later they found the most wonderful couple i could ever have asked for they have had bullies before so experienced with the breed and they where a perfect match for my boy, he has now been with them 2 years and i wont say i don't miss him still cos i do as he was my baby my world but so then so is my rottie and from the first week bully left my rottie actually had his first bone in years and ate it, the whole dynamics of the house changed my rottie was at ease you could really see it, he freely walked around unlike before where he would stay laying in one spot not moving because bully was walking about, honestly my only regret was that i didn't do it sooner i left the whole situation to carry on while i tried everything i could to make things better in hope i could keep all my babies with me ,
my Bully now is in amazing shape and doing excellent in his new home and we are all at ease, i know i done the right thing by him and by us all really, the situation just could and should not have gone on as it did for as long,
