<human>: Can you summarize the given text in a few sentences?

So about this time last year we got a GSD Akita cross. His name is Cave. He's great, super smart and I had him trained in a few weeks with clicker & cheese, so he can sit, paw, lie down, all that good stuff and housebreaking was barely an issue. Then a few months later we decided to get him a friend, he's GSD with a quarter husky thrown in for good measure, he's called Ludo. They get along like a house on fire, everything Cave does, Ludo wants to do to, he follows him everywhere, and he does not like when Cave is out of the house without him, this I think is part of the problem. 

Ludo is also super smart and has learned to play me. Housebreaking with Ludo again barely an issue, he learned sit really fast too, but then when I tried paw Cave was like "Hey I can do that! Here's my paw! Here's my paw! Here's my paw! What about the other paw?" So I end up giving him the treat and feeling bad for little dog and give him one too. OK so that doesn't work. Got my boyfriend to take Cave out for a walk to give me and Ludo some time to try paw and such. Ludo freaks out when Cave goes somewhere without him. I tried to distract him with toys and treats and such but to no avail and with thanks to the husky in him he's very shrieky and vocal about his displeasure... so that doesn't work and just gives me headache. I tried to put Cave outside so I can train Ludo, Cave can hear me and know's there's treats going on in here so he goes mad outside which in turn distracts Ludo. 

I know it's not a huge deal not being able to give paw and lie down and stuff but I just think the training I gave to Cave has got him to learn to respect me more or something where as Ludo is just wild sometimes and he doesn't really listen to me and takes his cues from Cave instead. Any ideas I can try?
<bot>: Older dog distracts younger dog when I'm trying to train him, taking older dog out of the situation doesn't work either cos little dog freaks out that he's gone. Suggestions please.
