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.
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.
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.
Well, it's not a very hygienic behavior. You could gently tell your mom that it might carry germs and it's not good for her health. Maybe suggest she wash her feet right away.
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. This kind of behavior is not appropriate at all. Feet are considered dirty in normal hygiene concepts, and this act violates normal social and family ethics.
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.
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.
Not at all. Consider a scenario where the wife was supposed to be watching the dog but instead the dog got loose and caused trouble in the neighborhood. When the husband catches her with the dog after this incident, there will be blame and disappointment. Or if the wife is using resources meant for the family on the dog in a way the husband doesn't approve of, it can lead to a negative 'caught' situation.
