Here's why:
* Hair grows continuously: Unlike fur, which sheds in cycles, Yorkie hair keeps growing. This is why they need regular grooming to prevent mats and tangles.
* Hair structure: Yorkie hair is more similar to human hair in its structure. It has a shaft with a medulla (core), cortex (middle layer), and cuticle (outer layer).
* Hypoallergenic: While no dog is truly hypoallergenic, Yorkies are often considered more suitable for allergy sufferers because their hair sheds less and doesn't have the same allergenic properties as fur.
So, while you might think of it as "fur" because it feels soft and fuzzy, it's technically considered hair.
