“Dogs have an exaggerated, ebullient, perhaps even excessive capacity to form affectionate relationships with members of other species. This capacity is so great that, if we saw it in one of our own kind, we would consider it quite strange—pathological, even. In my scientific writing, where I am obliged to use technical language, I call this abnormal behavior hypersociability. But as a dog lover who cares deeply about animals and their welfare, I see absolutely no reason we shouldn’t just call it love.”
