Yes, you can train your dog to not lick you by using positive reinforcement and redirecting their behavior. 


Start by teaching them a "no lick" command, and consistently rewarding them with treats or praise when they obey. 


Whenever they start to lick you, use the command and redirect their attention to a toy or treat. 


It may take some time and patience, but with consistent training, your dog will learn to stop licking you. 


Additionally, it's important to note that licking can be a sign of stress or anxiety, so it's important to address any underlying issues that may be causing this behavior.
