Can my dog and Cat ever get along?

I adopted a Cat several days ago from our local SPCA. I also have a three year old Miniature American Eskimo. The Eski is not rough with the cat, and just tries to give him a good sniff. The cat however, does not approve. The Cat will Hiss and growl...He hasn't lunged at the dog or anything, but I do want them to get along. Both of them are Males. The dog is Neutered, and the Cat has an appointment to be neutered on Friday. Any help? I tried introducing them by putting the cat in a carrier and then taking him out and letting the dog sniff the empty carrier..That didn't work!
