Instructions
Turn away from your pit bull when it tries to lick you. Pull your hand away if it goes for your hand. Ignore the dog completely as long as it tries to lick you. This takes all of the reward of licking away from the pit bull.
Praise and pet your pit bull as soon as it stops trying to lick you. Reward it with treats if you have some handy. This will teach your pit bull that it gets affection when it isn't licking, but gets nothing when it does.
Ask your pit bull to sit or lie down if it refuses to stop trying to lick you when you turn away. This gives it an alternative behavior. When it obeys, praise it and pet it to give it the affection and attention it desired.
Repeat steps one through three until your pit bull learns that licking will not get it attention. Be patient. It may take several weeks or even months until your pit bull changes the habit and stops trying to lick.
Ask your friends and family members (or anyone else your pit bull tries to lick) to ignore the dog until it stops trying to lick. Have them reward the dog with attention and affection when the dog stops licking. This will help your pit bull learn that licking is off limits for all people, not just you.
How to Stop a Pit Bull From Licking You
People may not picture a cuddly lap dog when they think of a pit bull, but the breed is actually a very affectionate dog. Though they were bred as fighting dogs for many years, pit bulls were always required to be tolerant of their handlers. Affection for humans is a genetic trait for most pit bulls. One way they show their affection is by licking their owners or their other human friends. Unfortunately. this might not be enjoyable for you or your family and friends. If you pet and talk to your pit bull when it licks you, you are probably reinforcing the behavior. Train your pit bull to show affection in other ways.
