Desperate for food and a home. Bring it to the shelter unless you're interested and have the money and time to invest in taking care of one.

It could be a stray. It wants something to eat. Like your leg. j/k

Dogs tend to spot decent people and will follow them.

Maybe dog thinks you look friendly, and expects some food from you, or at least petting.

It needs a home.
