Animal a = new Dog();

Will this be same as - Dog d = new Dog(); ?
Is there any special for method calling ??

It's different because of what methods you can call.

For example a.bark() will not compile if the method is declared on Dog while d.bark() will. In other words, you can only call the methods available on the variable reference type without casting.
