More precise than what? There is not a lot more information to be had.

1) You have overloaded the = operator.
2) You don't assign to that class using the = operator anywhere.
3) Therefore, the = operator is not called.

Next,

1) You have overloaded the Dog() constructor. This means you get to choose what you pass into Uncopyable().
2) You don't pass anything into Uncopyable().
3) Therefore nothing gets passed into Uncopyable(). It uses the default constructor.

It's not going to assume what things it shouldn't and shouldn't take from a custom constructor. If you wanted it to use the other constructor, you'd have to tell it, something like so:

Code:
Dog(const Dog &rhs):Uncopyable(rhs) {}
