Typically when a dog sniffs a person they are uncomfortable with, it's due to the pheromones that person is giving off. To the dog, those pheromones may signal a threat or an alarm telling the dog to beware. Humans can also give off pheromones that reek of fear or nervousness to a dog.
For example, if a dog doesn't like you, they may find some of your behaviors annoying, especially if you constantly do things that a lot of dogs are known to hate, like getting in their face, hugging them, teasing them, or yelling at them.

Many breeds are very protective, and many dogs have “their person” – so they will have a tendency to growl when someone else is approaching as a way to ensure that their special person stays safe. You may also see the behavior if they are friendly with other dogs and a new, unknown pet comes around.
Dog aggression can be related to fear, prey drive, socialization issues, and guarding territory, among other things.

It could be as random as someone wearing a hat, a shirt color, if they're sporting a beard or wearing glasses, and so on. A new person wearing something they haven't seen before may be unsettling to them.
Offer Treats from the Stranger/New Person
