not sure why name it there either if it is not used, yes size and name are instance variables because you can call them using one.size, two.size. If size or name was static then they would not be instance variables but merely variables. If I am wrong someone correct me please.

Just to confirm, if size and name were static then they would be known as Class variables and would be accessed via the class name. A reference of the Dog Class would not need to be created to use them.
In class Dog, size and name are instance variables.
In class DogTestDrive, one, two, and three are local variables on the stack.
I've seen this example before and I think it is part of a series of "snippets" and that later a constructor is used to pass in the name when a dog is instantiated.
