Your collie is your collie, end of story.

The eldlery person could be the father of 3 or 4 people, or the grandfather of 15 people. He could have a loving wife. He could have a weekly golf outing every Sunday. He could etc etc etc.

The brutally selfish and therefore immoral thing to do would be to keep your dog, and its not even close.

The tricky situation would come up if it was your dog vs. a convicted rapist that you've never met.
