One way is to simply distract the dog. For example, when you see the dog approaching the cat with the intention to lick, call the dog's name and offer it a toy or a treat. This redirects its attention away from the cat.
Once upon a time, there was a little kitten. It was a tiny ball of fur with bright blue eyes. This little pussy loved to play with a ball of yarn. Every day it would chase the yarn around the house, pouncing on it with its little paws. It brought so much joy to the family with its playful antics.
I've seen a mother cat that had just given birth. In the first few hours, she was constantly licking her kittens all over, including their genital areas. This licking serves multiple purposes. It not only cleans the kittens but also helps in the bonding process between the mother and her babies. It's an essential part of the early care that mother cats provide to their kittens.
The title 'little sis pussy story' is very ambiguous. It could be about a little sister's encounter with a small animal, perhaps a kitten which is sometimes called 'pussy'. Or it could be some sort of inside - story within a family or among friends where 'little sis' has an adventure or experience related to something named 'pussy' which might not be a cat at all but just a strange name for an object or situation in their private world.
