No, the purpose of a Ditto in breeding is for the Ditto to become the Pokemon its breeding with's opposite gender in order to make an egg. So, for example; Put a Ditto and an Arcanine ( no matter the gender) in the Pokemon DayCare and keep walking around and check on it every once in a while and when the egg comes just hatch it and it should be a baby Growlithe!
Hope this helped :D
