Dogs

They may be “man’s best friend,” but that doesn’t mean they aren’t dangerous too. Dogs are known to occasionally people, especially when they’ve been mistreated or aren’t used to strangers going near them. Apart from this, they can also carry the deadly rabies virus, transmitting it from other animals (like rats, monkeys, and bats) to humans. Rabies has been controlled in Western Europe and North America, but other parts of the world aren’t so lucky and still see thousands of deaths each year due to the disease. Rabies is mainly passed on through the bite of an infected animal and leads to a slow and hideously painful death if left untreated.
