Property Drawer on Extended Class

I'm having trouble getting a property drawer to draw an extended class, the setup is something like this;

Code (CSharp):

1.  
2. [System.Serializable]
3. public class Animal {}
4.  
5. [System.Serializable]
6. public class Dog : Animal {
7.     public float woofVolume;
8. }

The class that uses the Dog/Animal class;

Code (CSharp):

1. public class Kennel : MonoBehaviour {
2.     public Animal animal = new Dog();
3. }

And the property drawer;

Code (CSharp):

1. [CustomPropertyDrawer(typeof(Dog))]
2. public  class DogDrawer : PropertyDrawer {
3.     public override void OnGUI (Rect position,
4.                                 SerializedProperty property,
5.                                 GUIContent label)
6.     {
7.         EditorGUI.BeginProperty (position, label, property);
8.         GUI.Button(position, "Woof");
9.         EditorGUI.EndProperty ();
10.     }
11. }

So basically I want the inspector to display the property drawer for Dog when the animal property of kennel is a Dog, if I had a Cat and the appropriate Drawer for a Cat I would want the inspector to use the PropertyDrawer for Cat. Is this achievable with the property drawer system? Currently I can only get it to draw if I make property drawer use typeof(Animal)

 

For my case I can work around this with a switch but its not the dynamic scalable solution i wanted, still would like to know if theres a solution

 

Does your dog's woofVolume actually get serialized and deserialized properly? I was under the impression that using a subclass in a serializeable field like that will only deserialize as the super class.

 

You are missing an argument

Code (CSharp):

1.   [CustomPropertyDrawer(typeof(Animal), useForChildren: true)]
