thanks for your replies. they only done it yesterday with the new toys, they have got a pecking order normally, there has been no trouble today and have been given a rib each and theres been no fighting over them. they are nearly 20 weeks old and are brothers from the same litter. i think we have not helped by not going by their pecking order and are going to re establish that. they have never behaved like this before, normally the submissive one cries if he is seperated from the other and the other doesn't like it either. once the toys were out of the picture they were fine and it only happened with the new ones, the other toys have not caused this fighting, strange..... the only thing with the new ones were that they squeaked..... they do not fight over food and the one that is normally submissive will not eat the others, who is a slower eater. will monitor it carefully.
