Unlike the majority of humans, the dogs I’ve been privileged to know love their friends unconditionally. They offer up their beloved food or worldly possessions (prized playthings and blankets) and even their life if they think it’s needed. They take the greatest joys in the simplest pleasures. I have never understood why “dog/mongrel/cur” has been used as an insult. If anything it should be a compliment.
Now that I think on it, the best, most admirable people I have known come closest to acting like dogs.
