Several kinds of distractions and smells would ensure they have other things to worry about than just each other. The main idea behind the exercise would be to avoid the resident doggie becoming territorially aggressive. The scenario would be different with young dogs and adult dogs.

However, do not let them stare or sniff each other for too long, as it might result into a fight.
Understanding their body language

However, you should lookout for any warning signs of aggression. In such a scenario, get the two separated and distracted. Continue to introduce them in small intervals until they actually start admiring each other. Give them a command and when complied, treat them with a reward.

Only then, you should allow them to sniff each other in regular intervals. You should make sure your tone of voice has been in a positive sense. You would be required to continue using the positive tone or command along with the reward system.
