Another border collie with a purpose. Harley provides ears for his human. When the doorbell rings or the smoke alarm goes off, or even if the oven timer says dinner is ready, Harley alerts his friend to the sound and makes her follow him to the source.
Nancy says she is now able to relax because Harley hears the traffic sounds when they are out walking, helping to keep her safe.
Congratulations to Harley!
