How old are these dogs? You have a four month old puppy, Shane?
I'd say, pass on this opportunity - Shane needs all your attention and time. Very hard to raise two young dogs together, you will have to keep them apart a lot, and spend a lot of one-on-one time with each so that they bond to you and not to each other.
That means about one hour a day of the tow of them together, then separate play time with you, taking them to classes separately, exercising them separatly, training them separately.
Some people can swing it, I did when I had a puppy - but it took ALL of my time! I did not do anything else for six months but play, work, train with my pup and then with my older dog, until pup was older. Then they still need a lot of one-on-one time.
