Your dog licks your face because he loves you, right?

Ah, if it were only that simple.

There are those that will assure you that yes, those licks mean affection — your “fur babies” are showering you with, in addition to a little slobber, love and gratitude.

There are also those more scientific types who will dissect the act so emotionlessly as to leave you never wanting another lick again — or perhaps even another dog, or at least not another dog book.

Thank Dog, then, for Alexandra Horowitz, who in her new book “Inside of a Dog,” manages to  probe doggie behavior  in a manner both scientific and passionate, without stomping on the sanctity of the human-dog bond like it’s a cigarette in need of extinguishing.

The book’s title comes from the Groucho Marx quote:  “Outside of a dog, a book is man’s best friend. Inside of a dog, it’s too dark to read.”

What makes “Inside of a Dog,” released in September, one of the best dog books of the year is that it’s not too dark to read. Horowitz, a psychology professor, former staff member at The New Yorker, and long-time dog-lover is able — based in equal parts on her scientific research and her own personal experiences as a dog owner — to correct the many misconceptions about dogs without snuffing out the special light we see inside them.

As for those face licks, they have an evolutionary basis — it originally was a way for pups to encourage their moms and dads to regurgitate what they had eaten while hunting, thus sharing their prechewed bounty.

That doesn’t mean your dog is trying to make you puke everytime it licks your face, only that what’s now a ritualized greeting began that way.

The book gets to the root of other canine behaviors, as well, including:

· How dogs tell — and actually smell — time.

· Why it’s been futile leaving your television on for your dog all these years (and why this may be different now).

· How your dog really feels about that raincoat you make him wear.

· Why some dogs joyfully retrieve tossed balls and sticks while others just stare at you like you’re a fool for throwing them.

While not a training manual, it’s a book every dog trainer should read, and perhaps every dog owner who wants to truly understand not just what their pet means to them, but what their pet means.

The book goes into how dogs see, smell and hear the world, what their barks mean, what their tail wags mean. And it avoids the common oversimplifications associated with seeing dogs solely in terms of human behavior, or seeing them solely as modern-day wolves.

Horowitz, and the book, show some appreciation and understanding of the evolutions that have taken place, and continue to — the evolution of dogs, the evolution of humans, and the evolution of the bond between the two.

If you, like me, plan to curl up with a good dog and a good dog book (or five, or ten) this winter, we’ve got some suggestions for you. Please feel free to send us your’s. And remember the words of Groucho Marx — from whose famous quote the title of the book we’re featuring today was drawn:

 ”Outside of a book, a dog is man’s best friend. Inside of a dog, it’s too dark too read.”

Something old and something new sent two-time Pulitzer Prize-winning science writer Jon Franklin on a quest to document the transition of wild wolf to family pet.

The old thing was a photo — a man and puppy, exhumed from a 12,000-year-old grave. The new thing was a wife — he married a dog lover. Though he’d never been a dog person, Franklin gave in, and soon he and his wife were sharing their home with a clever poodle named Charlie.

Between watching his own dog evolve from puppy to family member, and his interviews and research, Franklin spent 10 years studying the origins and significance of the dog, and its peculiar attachment to humans.

The result is “The Wolf in the Parlor: The Eternal Connection Between Humans and Dogs.”

Franklin — a former science writer for Baltimore’s Evening Sun, now a journalism professor at the University of Maryland –  builds on evolutionary science, archaeology, behavioral science and his firsthand experience, arriving at the conclusion that man and dog are more than just inseparable; they are part and parcel of the same creature.

Do animals, grieve? Love? Hate? Do they feel fear, rage, pride, remorse, happiness, shame, envy, jealousy, sadness and all those other emotions that add texture and confusion to our lives.

You betcha, Marc Bekoff says in his Psychology Today blog, Animal Emotions.

“There is no doubt that many animals experience rich and deep emotions. It’s not a matter of if emotions have evolved in animals but why they have evolved as they have,” he writes. “We must never forget that our emotions are the gifts of our ancestors, our animal kin. We have feelings and so do other animals.”

The piece goes on to present some compelling examples.

Sea lion mothers, watching their babies being eaten by killer whales, wail pitifully. Dolphins have been seen struggling to save a dead infant and mourn afterward. What appears to be grief has been observed in elephants when a member of the family, a non-relative, or even a member of another species succumbs.

 Bekoff cites the case of  Gana, a captive gorilla, clearly grieved the loss of her infant in the famous image of her carrying her dead baby. Jane Goodall observed Flint, a young chimpanzee, withdraw from his group, stop eating, and die of a broken heart after the death of his mother, Flo.

Gorillas are known to hold wakes for dead friends, Bekoff adds, recapping the story of a female gorilla, Babs, who died of cancer Boston’s Franklin Park Zoo ten years ago. Babs’ mate was observed howling and banging his chest, according to a zoo staff member, then picking up a piece of her favorite food — celery — putting it in her hand and trying to get her to wake up.

“Why do animals grieve and why do we see grief in different species of animals?” writes Bekoff , the author of “The Emotional Lives of Animals” and Professor Emeritus of Ecology and Evolutionary Biology at the University of Colorado. “… Some theorize that perhaps mourning strengthens social bonds among the survivors who band together to pay their last respects. This may enhance group cohesion at a time when it’s likely to be weakened.

“Grief itself is something of a mystery, for there doesn’t seem to be any obvious adaptive value to it in an evolutionary sense. It does not appear to increase an individual’s reproductive success. Whatever its value is, grief is the price of commitment, that wellspring of both happiness and sorrow.”
