The city of San Francisco reported more missing dogs the week before a massive earthquake than any other week of the year. Therefore, this is factual evidence that dogs can sense impending danger.

This is an example of the logic fallacy called " post hoc ergo propter hoc", meaning roughly "after that, therefore caused by that". Another example: 99.99% of the people arrested for public drunkenness in the US last month had ice in their last three mixed drinks. Therefore, this is factual evidence that ice makes people drunk.
