I don’t see how they replace human relationships though. I have 2 dogs. 2 kids too! But yeah dogs are nice to have around. Sometimes annoying (barking, toilet incidents, training issues and so on)
Here if this helps: not the reason I’m holding on to being alive, the most important purpose I serve in the life I’m living. I don’t experience that with human children, but I do experience it with my pup. I care for her a great deal and she’s my most important responsibility. I really think it’s weird that this is such a foreign concept or needs this much explanation to anyone.
