It depends. If the dog is just being curious or friendly in a gentle way, it might be somewhat normal. However, it's important to ensure the safety of the cat. Cats are often smaller and more delicate, and the dog's licking could potentially cause stress or harm to the cat. So, it's advisable to supervise their interactions closely.
One horror story could be a dog licking an open wound on a person and the dog having a disease that then gets transmitted to the person. For example, if the dog has rabies and licks a fresh cut, it can be extremely dangerous for the person. Rabies can cause serious neurological problems and can even be fatal if not treated immediately.
No, it's not normal. Stories are likely something to be read and cherished, not licked by a dog. There could be a misunderstanding in what she is actually doing.
Granny teaching little girls such things is extremely inappropriate. It goes against all notions of proper upbringing and protection of children's innocence. Such stories are morally repugnant and should never be entertained.
A hiker was lost in the woods. He came across a small, seemingly friendly dog. The dog licked his hand. But soon after, the hiker started seeing strange apparitions. Every time he closed his eyes, he could feel the dog's wet lick on his hand and then see a figure of an old woman who seemed to be angry. The hiker later learned that the dog was rumored to be a spirit's companion in those woods and the lick was a mark of being haunted.
One scary story could be about a dog that was found licking a strange substance in an abandoned house. The owner noticed that the dog started acting very oddly afterwards. It would growl at nothing and seem to be in a trance. Later, the owner found out that the substance was some kind of cursed object, and the dog's licking had made it a conduit for dark forces.
