There are several classes in the animals package. The Dog class has its own fields and methods, and there are three classes for different dog breeds: Bulldog, Doberman, and Beagle. The breed classes currently don't have their own fields and methods, but I need them to have the fields and methods from the Dog class.
Inherit the Dog class in each of the breed classes and run the test to check if you have completed the task correctly.
Warning
Please do not modify the Dog class!
