Why is my Border Collie losing hair — Local Help in Philadelphia

Alopecia (hair loss) rarely occurs on its own — it usually comes with itching, scaling, or hormonal disease. Pattern and location give strong clues to the cause.

When it's an emergency

Take your Border Collie to a vet immediately if any of the following apply:

  • Rapidly spreading bald patches
  • Circular lesions (possible ringworm — contagious)
  • Open sores or bleeding
