My pig pulls her fur

[psychobillypigs]

I was watching TV when I saw that my pig was pulling on her fur so hard that her leg got lifted. I checked around her neck and legs, Behind, and nothings seems wrong. She is a peruvian so she has long fur, Do you think the lenght of the fur is the problem ? I cut her fur every month our so.
I have checked for signs of skin condition but she looks and acts healthy.

Has she done it again? It sounds like she was just grooming herself to me.

She has not done it today so i quess everything is ok. She grooms herself a lot but I was just worried about mites for a second.
