I need some advice on this, I have 3 dogs 2 of which are litter brothers, all are entire.
95% of the time they are fine with each other its just when the younger of the 3 gets told off he tends to start barking and goes for the one of the litter brothers this one is the most timid.
What is best way to stop him doing this. I dont really want to have any of them casterated if it can be avoided, also apart from the timid dog I cant say who out of the other 2 is the more dominent although only the youngest has these aggressive moments.
They are all fine at meal times although if he can get to the timid one he will push him out of the way and try and eat his food, we have to watch them.
The other thing I have noticed is the timid dog wont eat his food until the other two have started.
Can anybody give me some advice on this problem.

When I had trouble with son and father (son trying to be top dog) I would squirt him with water, this seemed to help. As for feeding I can't really say as I free feed and they eat when they want. All 5 of my dogs have their basic obedience down pretty good. Maybe when you feed them make them sit or laydown or something before you give them their food and make them wait till you say it is ok to eat and keep an eye that they do not steel each others food, I would also feed them a lil away from each other if this is causing problems. If they are not drawing blood and really hurting them selves then me personally I would let them sort it out for them selves... My two really started fighting and I knew Junior -dad would not back down so I stopped it, Dozer - son is the bottom of the pack and I haven't had any problems since and he is now 3 yrs old (knock on wood). I would squirt them with a water gun or spray bottle and then I would kennel Dozer that seemed to work and with in 3 days all was sorted. Guess Dozer just had to find his place, he tried it with his sister after that and she gave him a good tellin off.

The problem is not really at feeding times though, I can deal with this. Its usually if one is seperated  for a while and then they go back in, then I have the problem, also if the young one is pulled up for something he tends to react by starting on the timid one. Its not yet been a dog fight just growling barking and a quick snap by him then its usually over. I just feel for the timid one its not his fault but he seems to get it everytime.
Would casteration help at all, I dont want to but if it was a solution I may think about it.

What sort of things is the dog getting told off for?

I know a cocker like this, if anything upsets him he will start on his companion, things got so bad that the cocker has been rehomed.  He can't be kept with other dogs, he likes their company but can't be trusted not to start a fight if something upsets him :(   It can be something as innocuous as having visitors in the house, or even a knock on the door!!  and if he gets told off for something......:(
By the way he is neutered, this hasn't changed anything tho :(

Sorry I can't be more help

I must admit without seeing the dog it does sound like re directed aggression, but as always it is hard to say much on aggression without seeing it. He is frustrated at being told off but knows that he cannot be aggressive towards you, presumable because you are "top dog" in his eyes and so takes it out on his 'subordinate'. My BC does this when i take away her ball after a game, she will run and snap at my other dog, even though i was the one who took it away. Now i always make sure that when i take the ball ellis isn't so close by and meg can't take her frustration straight out on her. What is the dog being told off for? Is he frustrated because during the telling off you have prevented him from doing something? Can you describe a typical scenario where this occurs?

The problem mainly occurs when someone arrives, all the dogs run up to greet the person but Max growls at the chase (timid dog) so he goes away from the visitor.
Max also does this when we tell him off for jumping up, he takes it out on Chase, he does not do it to the other dog because he stands up to him, so it must be because Chase is so timid.
Is there any way tp prevent this, I love all my dogs and dont want to part with any of them, but equally I dont want this to continue.
