Short answer: most licking is normal dog behavior. It is usually a greeting, a way to get close, or interest in how you taste.
Why dogs lick
The AKC says licking is often an inherited behavior that comes from puppyhood. Dogs may lick to say hello, to comfort themselves or to show affection. Some also like the salt on your skin.
When it is just part of life
A few licks when you come home, or while you sit together, is ordinary. You do not need to correct a dog for a friendly lick. If you do not like it, you can calmly step away and reward your dog when they greet you another way, such as sitting or bringing a toy. For ideas on greetings, see jumping on you when you come home.
When to look closer
If your dog licks you, or licks floors, paws or the air, much more than usual, or the licking seems hard for them to stop, do not guess at the cause. A health problem or stress can both be behind it. Tell your vet what you have seen and when it started.
Get the right help
A sudden change in licking, or licking that looks compulsive, is a reason to call your vet first. If your vet finds nothing, ask for a referral to a qualified behavior professional.
