Because the environment is so hot that if they had hair, it would just make them unnecessarily warmer. It doesn't always benefit an animal to always have hair.

The part that's attached to the human or animal
Human hair can be distinguished from animal hair by examining the medulla, which is the central core of the hair. In human hair, the medulla is often absent or very thin, while in many animal hairs, it is typically wider and more pronounced. Additionally, the cuticle pattern and the overall thickness of the hair can provide further clues; human hair usually has a more uniform diameter and a different scale structure compared to animal hair.
ummm................ I'm pretty sure that in the winter animal hair grows quickly than human hair. but then in summer human hair increases so it is about the same rate.
The dog is obviously a land animal with fur, for fur and hair have different atom structures.
By definition, fur is the hair of an animal.
