Python - passing class instantiation to a function - python-3.x

Question

I need to pass the class instantiation to a function.
This is what i wrote so far:
def func(dog):
print(dog.get_name)
def main():
new_dog = dog(name, age, weight)
func(new_dog)
but when i try to execute it i get the following error message:
<bound method animal.get_name of <classes.dog object at 0x7f9611002b70>
Basically i have a class file with the following classes:
animal - Mother class(it include the name getter)
dog - Child class of animal
cat - Child class of animal
What i'm doing wrong?
--EDIT--
Structure of the classes:
class animal:
# public vars
name = ""
age = 0
weight = 0.00
animal_type = ""
# public constructor
def __chars(self):
print("His name is: " + self.name)
print("He is: " + str(self.age) + " y.o.")
print("His weight: " + str(self.weight) + " Kg")
def __init__(self, name, age, weight, animal_type):
self.name = name
self.age = age
self.weight = weight
self.animal_type = animal_type
print("A new animal has been created!")
self.__chars()
# public methods
def eat(self):
print("The animal eat!")
def drink(self):
print("The animal drink!")
def play(self):
print("The animal plays!")
def get_name(self):
return self.name
# public destructor
def __del__(self):
print('\n' + self.name + "has died :(")
# Child classes
class dog(animal):
__dlevel = None # dangerous level, it can be 0, 1 or more, it's private
# private methods
def set_dlevel(self, dlevel):
self.__dlevel = dlevel
print("Dangerous level set!")
def get_dlevel(self):
# CHeck if the level is define
if not self.__dlevel:
print("Dog dangerous level not found")
sys.exit(1)
# if is equal or more than 1 is dangerous
if int(self.__dlevel) >= 1:
print("The dog is dangerous, be careful while playing with him!")
# otherwise it's a quiet dog
elif int(self.__dlevel) <= 0:
print("The dog isn't dangerous")

Answer 1

I figured out the real problem: i was printing the function, not calling it.
So instead i've used
def func(animal):
print(animal.get_name())
def main():
new_dog = dog("max", 14, 11, "dog")
func(new_dog)
