How does a dog love?

Re-edited according to animals in translation by Temple Grandin and Catherine Johnson

All baby animals make a high-pitched distress call when they are separated from their mothers. Animal babies are totally attached to their mamas, and when they grow up most animals are strongly attached either to a particular friend or to the members of their social group, or both. Animals love other animals.

But on the other hand, domestic dogs don’t behavior like that they are social animals at all. A male dog on the loose will mate any receptive female he finds and then go tearing off to find any other receptive females in the area. We don’t really know what domestic dogs’ social life would be like if they didn’t live with people. Very few pet dogs have the option of mating with another dog for life. Dogs are pack animals. ;)

Like all complex behavior, sexual attraction and mate selection depend on learning. The act itself is a hardwired fixed action pattern, like the rooster’s courtship dance. It’s hardwired into the brain, and an animal is born knowing how to do it. He does not have to be taught. But an animal does have to learn from other animals who he’s supposed to mate with and who he’s not supposed to mate with.

A dog’s oxytocin levels rise when his owner pets him, and petting his god raises the owner’s oxytocin, too. That’s one reason why so many people have dogs in the first place. There is no anyone has researched this yet, but we will find that dogs make humans into nicer people and better parents.
