Training is still a no-go for Tucker @4-1/2mo) with another dog around. But for-fun walks with both can help them adjust to each other. Prepare to have 2 walkers though! My older dog is very well-behaved, and can be off-leash in all situations and I can count on her to listen completely, but walking both together can still be a challenge because of Tucker
My older dog has taken some time to adjust to him, and still doesn't LOVE him, so just take it slow and supervise closely. I let my older girl discipline to a point as I thought she needed to get a handle on him while she still could.
