Awwww. One of my shepherds used to bring toys & give them to one of the other dogs who was seriously ill. No question her behavior was purely altruistic. She would just bring the toy, drop it & walk away when she saw her companion not feeling well.
We have 2 cockers, an older blind female and a younger male. The male watches out for the female, always waiting for her to come out the door and go down the steps.
