Well, it could be a really cute story. Maybe your dog was showing affection. It might have been excited to see you and licking your hand was its way of greeting you.
Once, a dog licked my hand in a really creepy way. It was at an old, abandoned house. The dog's eyes were dull and it licked my hand so slowly, as if it was sizing me up. I felt a shiver run down my spine because the place was so desolate and the dog seemed out of place. I quickly pulled my hand away and ran.
A friend of mine had a dog lick his hand, and soon after, he developed an allergic reaction. His hand swelled up like a balloon, and it was really itchy. But what made it scary was that the doctor couldn't figure out what in the dog's saliva caused it at first. He was worried that it could be something more serious, like a new and unknown disease. Fortunately, it was just a severe allergy.
One scary thing that could happen when a dog licks your hand is if the dog has rabies. Rabies is a very dangerous virus. If an infected dog licks an open wound on your hand, it can transmit the virus to you. You might start to feel strange symptoms like fever, headache, and confusion. Eventually, if not treated quickly, it can be fatal.
Another element is the sense of contamination. The idea that something bad is being transferred through the licking. It could be like the dog is a conduit for some kind of malevolent spirit or disease, as I mentioned before about rabies or possession. And this feeling of being 'infected' by this unknown horror through the simple act of the dog licking your hand is very common.
No. I knew a guy who had a dog lick his hand, and later he got really sick. Turns out the dog had some rare disease. It was scary because he had no idea at first. He just thought it was a normal dog licking his hand, but then he started having all these symptoms like fever and weakness.
There's no way to really tell if it's common specifically for someone named Jojo. However, in general, reading fanfiction is a popular activity among fans of many different franchises. The Jojo series has a large and dedicated fan base, so it's likely that there are fans named Jojo who partake in reading fanfiction, but we can't say for sure how common it is without more data.
One possibility could be that the dog is infected with a deadly virus or bacteria. For example, rabies. If a dog with rabies licks your hand and you have an open wound, it could transmit the virus to you. Rabies is a very serious disease that can affect the nervous system and is often fatal if not treated promptly.
Perhaps this Jojo is interested in exploring different interpretations and stories within the Jojo universe that fans have come up with. Fanfiction often takes the existing characters, settings, etc. from the original Jojo series and creates new and unique storylines. So, this Jojo might be a big fan of the series and wants to see what other fans have imagined.
