 From the looks of Dog it should only hold one animal, so I would drop 
dogAppend and use a normal list; I would also change display to __str__ 
and remove the enumerate portion (since it's only one animal):

8<----------------------------------------------------------------------
#python 3
class Dog():
     def __init__(self, name, breed):
         self.name = name
         self.breed = breed

     def __str__(self):
         return self.name + ": " + self.breed

if __name__ == "__main__":
     dogs = []
     while True:
         name=input ("Enter Dog Name: ").rstrip() # stupid newlines
         breed=input ("Enter Dog Breed: ").rstrip()
         if name and breed:
             dogs.append(Dog(name, breed))
             for i, dog in enumerate(dogs):
                 print("%2i. %s" % (i, dog))
         else:
             print("good-bye")
             break
