Our dogs were not inherently aggressive, but we kept our daughter and them separated (completely) for the first year - 18mo of her life. (gates across door ways) They were not in the same room as she was, especially when she was on the floor playing.
Now our daughter is approaching 3 and we generally still keep the dogs out of rooms while she is playing, but they do interact, and she has always known to respect their space... "you do not touch the doggies while they're on their beds", "you do not touch their water bowls"
So, hopefully you can keep Joe and the baby separated, and as the months go buy, your family will continue to morph into what you all need.
If Joe likes walk, maybe a bunch of all-family walks, with the baby in a stroller will help everyone feel bonded.
