Wylie hates peanut butter. It literally makes him gag. That’s why this story, from several years ago, is still one of my favorites: It tells me something really cool about dogs.

When Wylie was about to retire as a guide dog, his best friend t work brought him cookies. Very special gourmet dog cookies. One problem: They were peanut-butter cookies. Deni graciously thanked her colleague and said gently that she wasn’t sure Wylie would like them; he was fussy. The friend said, let’s see. He offered Wylie a cookie. Wylie accepted the cookie with appropriate doggy gratitude and ate it. The friend went happily on his way, feeling good that his gift had been accepted and enjoyed.

Surprised, Deni offered Wylie another cookie. He gave her what she can only describe as a disgusted “Are you nuts? I don’t eat that garbage” look, turned, and walked away. He never ate another one of those cookies.

Was Wylie “just being polite,” telling one of those little “white” lies we all tell when we want to avoid hurting someone’s feelings? Can a dog do that?

Here’s a different way to think about it, though, really, we’ll arrive at the same conclusion: Dogs are very empathetic. They excel at reading and responding to our emotions. Many dog people have stories of dogs offering comfort when they were sad; getting excited when were excited; responding in a way that many people regard as “guilty” when we are angry. In truth, the dogs are more likely to be trying to appease a person they perceive as angry, but they are accurately reading the person’s emotion.

If Wylie got excited about the cookies, he could be said to be mirroring the friend’s emotion: The guy was presenting a gift that he had selected with Wylie in mind, and he was happy to see Wylie get the gift and enjoy it. Or the friend was sad to be saying good-bye. But Wylie didn’t get excited or offer comfort. He offered a gracious and appropriate, but not overly happy, response. (I don’t think Wylie is capable of phoniness.) And he clearly rejected the gift as soon as his buddy left the room.

My explanation is that Wylie was reading the situation clearly and accurately. He’d been around lots of people in lots of social situations, and he knew these two people really well. He behaved as he’d learned was appropriate. He wasn’t, I don’t think, consciously deciding to lie — any more than we consciously decide to lie each and every time we say something that will make someone feel good — or, to more clearly match this situation, every time we say or do something that is nice and socially expected rather than blurt out our first or most honest thought.

Jana, who really has no use for children of any species, is perfectly gracious and polite when being “enthusiastically petted” (she’d say “mauled”) by a child, but she gives me that look that says loud and clear: “Get me out of here, now, please.” And Alberta would dutifully “say hello” to people she and Deni met, but she really didn’t want to; and she expected a cookie as a reward afterward.

So, I would argue, that dogs read social situations and respond appropriately. What is “appropriate” in a given situation varies widely, and it is learned, not instinctive. Some dogs, and some humans, learn better than others. Some dogs do this well with dogs and poorly with humans, or the reverse. Wylie’s social instincts with other dogs were often less astute than his social instincts in this particular human instance.

So, while I’m not arguing that dogs adopt human social manners, I would say that they learn, over time with the same people, what those people think is acceptable. Much about dog-human relationships entails dogs trying to do what they think their human wants; it’s not surprising that this can get nuanced or that Wylie and Jana are good at it.
