"I have a dog."
Translation:Minulla on koira.
Finnish does not have a verb for "to have". We use the lla + on structure instead. In a way, you're saying "On me is a dog." The closest thing in English I can think of is "Do you have any money on you?". No "to be" in that sentence either but the preposition "on" matches the Finnish adessive ending, -lla. :)
