After a couple of days, I put them in the same room together but had the new
dog on a leash in case he did not like cats. He walked around her and tried
to smell her, but there was nothing agressive about him until the cat
attacked him.

As suggested by another poster, that is way too fast.  I suggest that you
look up some articles on how to introduce two cats, and apply the same
information to your situation.  I spent a full 6 weeks slowly and carefully
introducing Duffy and Holly (although I admit that I had warning that Holly
could be aggressive toward any other cat in my presence -- but the slow and
careful approach paid off with a happy twosome who are now good friends).  I
have previously posted some fairly lengthy descriptions of the process I
used.  Above all, you need to ensure that your cat (the original resident in
your home) does not feel that she is being displaced by the dog.  Give her
*lots* of attention every time the dog is in the room with her.
