The importance of hair in a dog and its types of hair

First of all, it is important to know that dogs have 3 types of hair:

  • Primary hairs. They are the ones that form the outer part of the mantle and have the ability to stand on end.
  • Secondary hairs. They are the ones that are part of the inner fur and are responsible for providing protection and keeping heat.
  • Modified hairs. They are the mustaches or the eyebrows, which serve the sense of touch.

Likewise, hair growth is determined by a cycle that has 3 phases:

  • Growth.
  • Transition the hair stops falling.
  • Rest or fall of dead hair.

The three phases occur at the same time in the dog, although one of them usually predominates. That is, depending on the proportion of hairs that are in one phase or another, we will notice less or more hair loss. When this normal cycle is disturbed, you will notice more hair loss, even bald spots in your dog's coat.
