Hi, I wonder if anyone could help me [-o< I have a 9 month old mastiff x Amstaff (Obi) and up until now he has been perfectly mannered towards my other 2 dogs. Over the last few days he has started to become aggressive towards them, not all the time, only in the evenings so far.

He is baring his teeth and growling, tonight he lunged at my lurcher but I managed to stop him getting him. I'm really worried about this and don't know what to do about it.

Normally all 3 dogs get along really well, they sleep together in the same room, play really well together inside and out, lie and cuddle up wth each other etc...all the things we expect our dogs to do.

I have a feeling it may have something to do with him being possessive over me as nearly every time he has been nasty he has been sat near me or lying on my bed. I took them in the kitchen about an hour ago, just after he'd gone for my lurcher and gave them biscuits, they were all sat together in a line and there was no aggression, as there never is around food.

Does anyone have any ideas what might be wrong with him and what I can do about it? He's only 9 months old and already very heavy and powerful, I don't want to end up with this being a lifelong problem.

Thanks in advance

Thanks for the replies. He was neutered about 2 months ago, he had shown some small signs of food aggression just before this. If we were sat eating he would sit in front of us and growl if any of the other dogs came near. He now knows he is not allowed anywhere near us if we are eating. There is no food aggression with his own food, he does eat seperately though.

It seems he has claimed me as his own so now I need to stop that, my partner suggested last night that he goes in his crate during the night, that's what we are going to start doing.

We are also moving house soon and we are going to have a 'no dogs upstairs' rule, they will all sleep together in the conservatory.

Hopefully I can nip this in the bud before it becomes a real problem.

I was warned by my trainer that he may start to act differently around 9 months old, this is obviously the behaviour she meant :roll:

Since I first posted this thread I have been watching him very carefully and I have discovered that he mainly gets his 'nasty head' on just after they have all been given treats. He is always last to receive his, Samson first, then Zook then Obi. Afterwards he justs gets all edgy and I don't know why. They all get an equal amount of treats and all have the same thing. He's never aggressive or nasty over food or after they've all just eaten.

I have managed to keep him away from me when i'm eating, if he walks over when I first sit down he gets told to "go away" he then goes and lies in the corner of the room.

Fortunately I can recognise very early when he is getting a "head on" so I quickly reprimand him, sending him out of the room and leaving him until I am comfortable to bring him back. I am careful not to over fuss any of my dogs as I know that they are very jealous creatures, if one gets a cuddle the other 2 get one aswell..

I think maybe he is at the age where he is going to start pushing his luck and I need to over rule him on all this behaviour. There has never been a fight, which I am glad of. I know if he really went for my lurcher he'd do some serious damage to him.

I'm really not experienced enough with this breed of dog to be attempting alpha rolls, I think verbal commands are going to be the only way for me.

Clara is food possesive. Therefore she is fed in her crate and she takes her
dog treats in her crate as well. She is put into her crate when it is time to feed the other dogs.
As long as she is seperated during food times, she is just fine. You might try this with Obi.
Obi was fed in his crate from the day we got him but then for some reason, can't remember why, we sarted to feed him in the living room and the other 2 dogs in the kitchen. There was no problems as the other 2 were kept out until he had finished.

I stopped giving the dogs treats about 3 weeks ago as every time they had them 5 minutes later Obi got his nasty head on and started biting Zook.

2 weeks ago his glands scooted on the carpet and he really went for Samson, it was proper aggression but fortunately I managed to seperate them. There was no blood but Obi really was going for it, he was in a proper fighting stance, back legs dug into the floor while he went for it on Samsons shoulder. 2 days later he went for Zook in much the same way except this time he also tried to mount him (typically dominant).

We realised that we had some pretty hard decisions to make with regards to keeping Obi, we can't afford to have an aggressive dog as Neils children come to stay every other weekend and when Obi went for Zook one of the children was stood next to him. It appears he was protecting the child. Zook went to walk past and Obi just flew at him.

I spoke to the breeder and she basically said we need to get more assertive with Obi and stop spoiling him, not that we do really, since first posting here and realising where we were going wrong we stopped spoiling him altogether. She also said he is fighting for spot of top dog with Samson, which we already knew, we just don't know how it's going to end.

We are going on holiday in 2 weeks and Samson goes to stay with Neils mum when we are away so we took him there last weekend, so we can spend some time working with Zook and Obi. It's going ok so far, only 1 fight and that's because we tried to give them treats the other night to see what happened. About 3 minutes after they ate their treats Obi was lying in his crate and Zook walked into the kitchen to get a drink...Obi flew at him and they had a bit of a fight, nothing much as there was no blood or marks on either of them. So we've decided that there can just be no treats in this house for any of them. The only thing we're worried about is, what happens when Samson comes back??

I wouldn't be happy to rehome Obi as he really is a big baby and hates being away from us, I think he'd die of a broken heart if he had to leave us. Obi and Zook get along really well just the 2 of them and i'm starting to believe that the saying "2 dogs are company 3 are a crowd" is true Just don't know what to do.

Any more advice on this would be really appreciated.

Thanks for that :) I understand totally where u are coming from about the rehoming thing. The breeder has said she will keep an eye out for a suitable home for him just incase we do need one.

He has never been aggressive towards the children, he's barked at them occasionally if they scare him but about a month ago one of them kicked him really hard :shock: he didn't think I was in the room. Obi didn't bat an eye, he just walked away as if nothing had happened, so there's definitely no aggression towards the children.

We are hoping to move house soon, infact move to a different country, so we'll very rarely see the children so that won't be an issue. If we get the house we are hoping to get we'll have alot of land with it so alot more space for the dogs to run around and wear themselves out.

We'll just have to see what happens. I'm going to take him to the vet and get hm checked over, his glands are scooting almost constantly and he keeps biting at the base of his tail and doing some really weird looking poohs. If he is feeling a bit grotty this would obviously make him grumpy.

I'll definitely let you know how we're going along. Might have to go back to training classes with him.
