They are being puppies. It is the reason most people would not contemplate having two together. they are bonding and acting as dogs, you are secondary to them. Training witll be a lot harder. The only way it ever really works is if you treat them as if they were two pups living seperately with time to visit each other as if they were visiting a doggy pal.
You will need to seperate them at night into seperate crates, best to let them be close to eachotehr as now they will howl if seperated as they would have done if taken from the litter.
You should also walk them mostly seperately, and train them on their own until they are grown up.
Two pups is not double trouble but trouble squared :D
Persoanlly if you got the two to get them out of a bad situation I would try and find a good home for one of them and keep just one, otherwise you are looking at two long years before they will be well adjusted and treained pets. I assume you are at home all the time, if not then I realy urge you to think hard about the time and commitment needed to train two pups when one wouyld need all your spare time.
