Just an update that pup and my other dog are doing okay so far, although they're not playing together (my dog just walks away from the puppy when puppy tries to chase).
And the puppy is doing very well too considering how young it is. He is very happy and smart and curious. He loves sleeping in his crate and doesn't cry at all over night. He is very rambunctious when he's awak during the day and A LOT of chewing - he tries to bite my feet and toes a lot So far when he does that I tell him no and give him a toy but he prefers my feet!
