myPDO.class.php -> Singleton. Makes the connection to the database possible.

generalDAO.class.php -> Abstract DAO Class, grabs the myPDO instance and could 
have other methods on the future that are shared for all the DAO classes.

AnimalsDAO.class.php -> DAO class with insertAnimal(); deleteAnimal(); 
updateAnimal(); countAnimal(); selectSpecificAnimam() methods...

The same goes for the VetDAO.class.php.

According to the above, does this suggestion of yours still apply? 
If so, what is the buzzword that I should look at so that "inherit that for 
specific types of data like animals" could be possible? What/where should I 
look/search to accomplish your suggestion?
