How many dogs have been eaten by sharks?

There is no reliable data on how many dogs have been eaten by sharks.

Here's why:

* Rare Occurrence: Dog attacks by sharks are incredibly rare.

* Lack of Reporting: Even when they do happen, they are often not reported or documented.

* Uncertain Identification: Sometimes, a dog's remains are found, but it's difficult to confirm if a shark was responsible.

Therefore, it's impossible to say how many dogs have been eaten by sharks. However, it's important to note that while shark attacks on humans are more common, even those are extremely rare.
