First, it's really strange behavior. You could gently talk to your wife about the potential hygiene issues. Maybe she doesn't realize that the dog's mouth can carry bacteria. For example, dogs may have licked dirty things before and then lick the stories which might contaminate them.
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.
No, it's not safe. A dog's mouth contains a lot of bacteria which can cause infections in humans. Even if the dog seems healthy, it can still carry harmful microorganisms.
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.
It can be normal in some cases. Dogs often show affection by licking. But it's also important to consider your wife's comfort and any potential health risks. If your wife doesn't like it or is at risk of an allergic reaction, then it's not really acceptable behavior from the dog.
You should immediately stop the situation if it's happening at that moment. After that, educate your wife about the possible diseases that can be transmitted through such contact. It could be something like salmonella or other infections. Also, make sure the dog has regular vet check - ups to ensure it's healthy and clean.
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.
I'm not sure what to make of that. It's a rather unusual and personal situation that could have various meanings depending on your relationship and dynamics.
