Our last cat never took to Lola let alone Lola, Zeb & Casper
Think she was too old & crotchety to accept them.
We now have 2 kittens and keep bringing them down and sitting behind the stair gate with them and letting them see & smell the dogs, we also rub blankets on the cats & dogs and let the dogs smell the cats blanket & vice versa.
Zeb has met Daisy (boldest kitten) face to face and was so gentle with her

She did however hiss & try lash out at him but he didn't freak or anything so he got a treat for being calm. Casper is pretty calm too. It's Lola that's quite 'excitable' shall we say
I am hoping that they will accept each other as they are going to be housecats.
I think your prospects of them both getting on are good as your dog is a pup.
