How to use properties of optional object argument

I have this code:

function getName(type, options) {



    if (type == 'dog') {

        var name = 'Rover';

    }

    else {

        var name = options.name || 'Buddy'

    }



    return name;

}

alert(getName('cat'));

I was expecting the variable to be assigned to 'Buddy' but instead I got this error:

Cannot read property 'name' of undefined

Is there a simple way to handle this? I'm hoping for a one-line piece of code. I was thinking about using this but it seems long and unnecessarily complex:

var name = (options !== undefined && options.name) ? options.name : 'Buddy';
