So sorry for your loss - border collies have a way of bonding that is sometimes unfathomable.
Thank you. Many heartfelt posts from animal lovers. My girl would freak out if she couldn’t find me and when I returned from a flight after a couple of days she’d be running around me in circles. Right now I’m just numb although I expected her failing for a few weeks before I had to take her to the vet; incontinent, no appetite, wouldn’t drink water.
