The length to which hair grows on the average life span of the hair (root of the hair actually).. If the average life is long, then the hair will grow long.. but if it is small, it will fall off before it gets long...
The hair is continuously falling off.. So what you see as the length of hair, is only the lenght of the longest among them.. there are smaller hair growing all the while, trying to catch up with the longer ones.. and they do.. when the long hair stops growing for a while, before it falls off...
This applies to all.. humans and animals alike...
For animals, the life span of the hair is lesser, but uniform throughout most of the body.. For humans, it is more on the hair and face, but is lesser in other places of the body...

Most animals have fur which only grows to a certain length and then sheds and starts the process again hence why cat owners and such always have fur around and can cause an allergy. Certain breeds on the other hand, say the Maltese dog has hair which grows until cut like that of a human,these animals are considered allergy safe because they have hair not fur which doesn't shed.

Some animals fur/hair does get too long. Think of a horses tail for instance. And pubic hair grows to only about a certain length, generally speaking. It's all a matter of genetic's.
