Why Do Dogs Lick People?

5. Anxiety

Licking is a soothing behavior for many dogs, so some dogs will begin to do it compulsively if they live with a high level of fear or anxiety overall. This type is licking is usually somewhat obvious, as it isn't just a couple of friendly or playful licks. Instead, anxious licking tends to be a steady, repeated behavior that the dog does for long periods. If your dog engages in this kind of licking, you may want to talk to your vet and trainer to find ways to relieve his anxiety.
