You'll find a lot of people on here with more then one dog. Can you take them outside in your yard on leashes where they will be on neutral territory. Don't walk them side by side but maybe find a way to tie them loosely close enough together where they can't get at each other, but can do the sniff thingy, or I have sliding doors with a fenced yard, so I'll put one outside, and one inside so they can look at each other, but not hurt each other. I think what might have happened is that the first one you had decided he was Alpha as he was the first one there. It will just take some time, and patience. Best wishes. If you have questions you can surely pm me.
