Hello again, i am very sad to have to be here again needing more advice as it seems things have taken a turn for the worse , and just when i thought all was well,
My bully boy yesterday had been growling at my mum ( anyone who knows me will know my 67 yr old disabled mum comes to live with us from November till March every year)
twice yesterday as mum walked past him in the passage he growled i told him off twice and he clearly took no notice as the third time she went by he jumped up to bite her,  at that point my Rottie jumped in and started fighting with bully , my poor mum was knocked over in the scuffle myself and hubby where quick to part the dogs it didnt seem like rottie was really going to rip my bully apart more like he got bully in a bear hug and seemed to be trying to pin him down, but bully boy is as iv said before a dog that dont want to stop and i feel would fight to his death, its always him we have trouble getting to stop,,

Now i do know my mum favors my rottie and will make a fuss off him more than bully boy so i now wonder if its her fault or am i just looking for excuses to not blame my bully,  (i love him so much ) now i have my family all telling me i must rehome him or castrate him , i'd prefer the later of these options,
i am feeling very resentful at my mum right now as i do feel she somehow caused this situation and maybe done something to provoke the incident, she really does not listen when you say to her Not to give the dogs treats when their all together as i know their are jealousy issues she also dont listen when i keep telling her not to keep talking to the dogs in her silly baby style voice which gets them all excited, ohhh help can Anyone help me rehome my Mother please ;-),,,,

Just commenting on this part: your dog did take notice of being told off for growling, which is why he had to go straight for a bite next time. If he can't growl and therefore warn that he is unhappy about something, his only option is to bite. The question is WHY he growled at your mum -does she walk in an odd way for instance? It's vital to pay attention when a dog growls, work out why and act on it, and never tell them off for warning us.

Thank you Goldmali, yes my mum has an artificial leg and walks very badly since braking her hip a few years ago also,
when i say tell him off it was more like a "oi behave yaself" call from the kitchen i gave,
i know i probably should have taken more notice when he did growl but was in middle of dishing up dinner and mum will keep coming out (in out in out it really makes me even want to bite her :-/) each time she comes thu the passage bully would have to move or she has to claim over him and she cant really do that easily, to be honest i am feeling the strain of my whole situation more this year than any other since she has been coming here,
but i really dont want to blame my bully as everyone else in the house is doing,
i think my rottie was just being the protector in going for my bull as if it wernt for him then bully would have managed to bite mum for sure,,
its just a very hard situation at this time of year with mum here and i need to now be more cautious than ever,,, i have had hubby on my back this morning asking have i called the vets about getting him castrated :-O ,,,,(No i havent,, the local care home for mum would be my first call i think) opps sorry im i bad!!,, and i dont know for sure castration  would work for him and his other issues, (bad recall ,jealousy, ohh to me he's a typical bully)  i cant seem to make my family understand that it is not bulls fault,,,, and why should i chop off his bits because he is what he is!,
the good news is no one was hurt Dogs have a couple of minor grazes thats it and mums fine,, i just wish they would all understand i feel they are trying to push me into rehoming him the way hubby and mum talk you'd think he was the dog from hell, i know he has his issues but he is a good boy really, its just all really upset me,

Basically Bully has best be kept out of the passageway where the issue arises. 

It is likely that your Mums movements worry him, especially if the tries to step over him.

So he needs to have a different resting place, and be prevented from being where there is 'Mum traffic' so he doesn't have negative associations with Mum.

Either training him to stay somewhere else or containing him with the use of a gate or crate.

and i dont know for sure castration  would work for him and his other issues, (bad recall ,jealousy, ohh to me he's a typical bully)

Ask OH if HE would be more likely to do as you told him if he was castrated. ;) If the answer is no, he has his answer to the dog as well. Castration prevents pups being sired, nothing else.

I do agree with Brainless it sounds as if all you can do is try to keep the dog out of the way. I know it isn't always easy -I have my disabled 84 year old mother in law living with me, but we've managed as we've had to.

I would agree with Barbara. My mum had difficulty walking and I used to put dog out of way when she was moving about. I had to walk with her so would tie dog up which suited us, eventually I didn't have to as they all learned to move out of way by themselves.

Since your dog is worried I would put behind a gate and also not put Rottie in with him

If your Bully is normally friendly with people and it is only your mum in the house that he is growling at then it sounds as though like everyone has said, her movements are probably worrying to him.  Also is she anxious/nervous around him?  It is amazing what dogs can pick up on.  I know my male Rottie can be a little pushy if anyone is slightly worried by him....to anyone who loves Rotts he is a baby!

I'd recommend finding him a nice safe space to rest in where he isn't going to get constantly disturbed by your mum walking past, also this will stop her from feeding treats to them and causing issues there aswell.

yes he is genuinely very friendly with everyone, i don't blame him at all, as i have already said mum (god love her) was being a bit of a pain that day i could have bit her myself lol, Ahh thanks to all of you who answered me i new you lot here would understand and have some good common sense answers for me :-) ,, unlike my family who seem to want to comdem my poor bully boy,
oh yes and i did suggest  to hubby we get his own balls chopped off and see if it would help with his snoring lol,, to my surprise he wernt to keen looool
thanks everyone xx hope you all have a wonderful christmas and a very prosperous new year x
