These two sentences have the meaning.Take care , most of people think that there is a huge meaning.

 Have you a sister? It is true but it was in Shakespeare’s time . It is super super formal  or you  may say it in front of the queen or the president.

She is a dog            =          she’s a dog.

She has a dog           =        she’s a dog.
