I think you should wait until you have your current dog under control. I know you say you will have enough time, but you may for a bit then it will dwindle away. I adopted a 3 yr old German Shepherd and I only work one part time job I work 6am to 2 everyday and am off two or three days out of the week, so I have plenty of time to train him and he has been a huge responsibility and am still working through some kinks. The people here are not telling you this to make you mad or feel like an inadequate dog owner they give so much good advice, because most of them are more experienced.
When I got chief he was severely severely aggressive towards men and not really keen on meeting new people, he was super aggressive over his food, knew nothing about a leash and ran wild in the house, he didn't know what toys or bones were. He was like having a brand new puppy except huge, aggressive, and with big teeth. I also have another dog who is 17 years old he loves other dogs and adores Chief.
Back in his younger days I would have never thought he would like any other dogs especially males since his past with the, but now he loves all dogs expecially Chief. Having an older dog that you know hates puppies if putting him through stress that he doesn't need to go through and it's not good for his health.
You have way less time that me and having a new puppy and an aggressive older dog just isn't a good mix. Wouldn't you rather have them both get along or since you say dog 1 likes adults why don't you get an adult instead of a puppy and let your older dog meet him before you bring him home. I had my two meet before I even said yes to taking him. I didn't want either dog to be stressed, but they were almost instant friends
R.I.P- Smokey my GSD/Husky. You are my hero, my heart, my soul and you will forever remain in my heart. You were a true companion. I love You and miss You so much. Run like the wind!!
