Unless your dog is Lassie, you probably can’t always tell what your beloved pup is thinking. Stanley Coren, Ph.D. (stanleycoren.com), whose books include How Dogs Think ($16, amazon.com), The Intelligence of Dogs ($20, amazon.com), and How to Speak Dog ($15, amazon.com), and Jonathan Klein, founder of the “I Said Sit!” School for Dogs, in Los Angeles, offer their expert opinions on interpreting a dog’s expressions and behaviors.
Smiling
Ever looked at your dog and thought, She's grinning at me? It turns out she is. Like humans, a dog “smiles” when it’s content.
The muscles in the body are relaxed, which you’ll notice most by observing the face: Instead of clenching its teeth together,
the dog lets its mouth hang open. The tongue is relaxed and hangs loosely, so that it’s visible over the front of its teeth.
The eyes are soft and the ears are straight. Bottom line: When you see your dog smile, she’s content, and you should be, too.
Growling With More Teeth Visible Than Gums
When a dog growls, he’s letting you know that he’s uncomfortable. He’s either scared or trying to show dominance. Look at
his mouth to determine which is the case. If it’s open in a C shape—displaying lots of teeth and little gums—he’s essentially showing his weapons. The dog is sending a clear message:
“I’m the boss around here. Back off, give me space,” says Coren. You can defuse the situation by doing just that: Give him
room by backing away slowly.
Growling With a Lot of Visible Gums
If a growling dog's mouth has an elongated shape with a good deal of the gums visible (it looks as if you “took the corners
of the mouth and pulled back,” says Coren), your dog is probably frightened and prepared to defend himself. His ears may also
be flattened. A growling, fearful dog is often more dangerous than a dog showing dominance, because his survival instinct
is to lash out. While backing away from a scared dog is your best option, it may indicate weakness to the dog. If he charges,
stand still, keep your arms folded and make no eye contact (stare up at the sky, for example). Under no circumstances should
you turn your back on the dog.
Standing Tall
In general, someone who wants to tell the world, “I'm in charge!” will try to make himself as big as possible. The same holds
true for dogs. A dog with a taste for power will stand “very tall with legs quite straight” and its body will be tensed to
allow for maximum height, says Coren. The dog may also raise its tail over its body like a flag to make certain that no one
fails to notice him.
On Its Back
If a dominant animal goes high, it makes sense that a frightened one goes low. A scared dog will lower its body and drop its
tail. If it’s extremely anxious, it will roll onto its back, displaying its belly and throat. A dog who adopts this pose is
essentially announcing, “I’m just a wee puppy, don’t kill me,” says Coren. If your dog is this distressed, make sure you—and
anyone else nearby—slowly back away until she calms down.
