Licking comes as a natural instinct in dogs, it’s a habit that is cultivated from the time they are puppies and sometimes it continues into adulthood. During birth, the mother usually licks her puppies to stimulate breathing, she also does so when cleaning herself and the puppies as well stimulate defecation.
Excessive or too much licking can be a source of concern to owners and many always wonder how to put an end to it, excessive licking is usually a behavioral or medical issue.
Excessive licking out of habit or behavior
It’s a way of maintaining hierarchy in a pack or litter. Subordinate dogs are found to lick the dominant ones and helps maintain harmony.
Dogs also lick to due to anxiety, nervousness or boredom. Licking releases endorphins which helps them to stay calm.
