On some level everything that G-d has created knows Him. This was universally understood before the Left co-opted animals and nature.
So what we interpret with those puppy dog eyes as love is something more associated with feeding and ease rather than an inate love for another kind.
Anyone who has ever had a pet knows that his pets love him.
I don't deny a dog's love ... but I contend, (and previously owned/adopted animals seem to bear witness), the "love" is based on the care of the dog.
Perhaps I should qualify MYself ... I believe love is a decision, not magic and fireworks.
We learn the magic and fireworks as we discover our decision was a good one.
