Lifetime dogs intersect with our lives with particular impact; they're dogs we love in especially powerful, sometimes inexplicable, ways.

Some rescue groups are highly organized, experienced, well-funded, nearly professional. Others are small amateur operations run out of garages and back yards. Their members may identify strongly with animals as victims, sometimes because of traumas and disappointments in their own lives. Others simply love animals and want to help them.

There is no evidence that dogs have the kind of complex emotional lives and value systems that we do. It's one reason why we love them so much, in fact. They are neither ""good"" nor ""bad."" They don't hold grudges, act in petty ways, or seek revenge. They read our moods, but not our minds.

Kids leave us and go off on their own lives. Family members tell us what they think of us. Animals can't do that. They really are blank canvases, and we can project anything we want onto them. So the relationship is very pure and simple.
