How to stop a dog from licking people:

1. Ignore it. When a dog licks someone, just walk away, ignore it, and ignore it for a while to let it understand that such behavior will make the owner unhappy.

2. Replace cleaning supplies. It is possible that the scent of the soap or shower gel used by the owner is very attractive to the dog, and the owner can change it.

3. Apply a smell it doesn’t like. If the dog often licks the owner's hand, the owner can apply lemon juice on the hand and lick it deliberately. After the dog licks it, it will find it tastes bad and will stop licking it in the future.

4. Use pheromones spray. Pheromones have a calming effect, which can help calm the dog's mood and make the dog less excited.

5. Divert attention. When a dog is obsessed with licking people, the owner can do other things with the dog to divert its attention.
