You can let them sleep together if that is what you are comfortable with.

However, I would definitely feed them out of different bowls, you want to know how much they are eating.

Also, make sure they have some time away from each other, separate training time, etc... you want to make sure that they are confident and happy on their own as well as together.

I would also introduce them to your current pup individually... this way he doesnt get overwhelmed.

Good Luck!
