Puss aka the Tiny Pampered Princess (housecat) is 11. She has a new 'little' sister in the form of a one year old bouncy dog, Pooch, of dubious breeding. (Pet names changed for illusion of privacy!). My DP and I got the dog together, but Puss was mine for many years before we started a relationship.
Puss lived with dogs for the first year of jet life, but that was a long time ago. She is very territorial and tries to attack passing cats through the window....
Puss has now retreated upstairs in disgust and will not come down into the living room. She will sit on the stairs and not pass the baby gate we've put up at the bottom to prevent Pooch going up. She can see into the living room through the banisters and sits there all evening, scowling at the dog.
Pooch is of unknown breed, but supposedly fine with cats. Pooch has been with us about 3 weeks. She's not tried to attack the cat, but is always staring at her. It's hard to break her obsession, but she can be distracted with play or food. She is a very inquisitive beastie, and I suspect that she just wants to sniff Puss and see what she is up close.
Pooch does get nose to nose with Puss through the banisters occasionally, but usually Puss legs it if the dog makes any noise like a whine.
I think Pooch is part sighthound, part Collie, part Husky.
What do we do from here? Force a meeting? Definitely not my preferred option. Ignore it and hope to god my cat comes downstairs? Tell the dog off every time she looks at the cat? Stop the dog sitting where she can see the cat?
How did you do this sort of introduction?

)We've always had a strict rule - 'Dogs don't go upstairs' - and the cats know it. (Border collies so they're massively trainable. We've never needed stair gates.)
I'd be ensuring that Pooch has as much solid exercise outside as you can manage - she looks as if she'd be a glutton for it - and then leave them to it. (While enforcing the 'not going upstairs' rule, using your gate as necessary because that's one heck of a mix Pooch has in her and she's only young.) If the cat has a good safe area, she should be fine.
I'd, personally, also put a tray for the cat and a feeding station upstairs so that she has all her orders up there if needed.
Good luck.

Ah that will be the sighthound in her. (The slugabed bit.) Collies, in my experience, just live and breathe 'work'. ( Which is what their walks become if they're not working dogs.) .They watch you, waiting for the chance to serve. 
(I don't know huskies.)
