I got Andy and Barney at the same time they were full brothers and we couldn't seperate them, so we got both! Yes for me it was a lot of work having 2 pups at the same time but very well worth it. Maybe since one is older for you the housebreaking part won't be too much of an ordeal. It always seems like when one is ready to go out the other isn't
But I would do it all over again...
