Dogs with separation anxiety exhibit distress and behavior problems when they're left alone. Some of the most common ways they do this: Digging and scratching at doors or windows attempting to reunite with their owners. Destructive chewing.
Dogs rely heavily on their noses and have a much more sensitive sense of smell than humans, so they're naturally more attracted to sweaty parts of the body, like the groin area.

Dogs are able to smell through glass. However, if a glass container is airtight, such as a mason jar, a vacuum has been created and no air is able to escape. Therefore, no odor can escape and a dog is not able to detect a scent.

Some may dislike hugs more strongly than others, and some may actually adore them. The closest thing our furry family members do to a hug is something referred to as 'standing over'.
For humans, these glands are concentrated in the armpits and genitals. Since a dog can often only reach a human's genitals, that's where they head to gather information. Scent hounds, such as Bloodhounds, Basset Hounds, and Beagles are more likely to sniff at crotches due to a highly-tuned sense of smell.
One of the most common reasons why dogs love to lick their owners is simply to show their affection. Since you're the one taking care of them, you're essentially their world! When dogs lick, pleasurable endorphins are released into their blood which makes them feel calm and comforted.
