Well the Chopper situation is looking good! The breeder keeps saying I am a perfect match, and I just got an e-mail from a possible rental that would allow her. I hope I can get down to see her soon...

The article gets into more than just dogs, but I thought this was a pretty cool finding.

If You Want to Know if Spot Loves You So, It’s in His Tail

By SANDRA BLAKESLEE
New York Times, April 24, 2007


Every dog lover knows how a pooch expresses its feelings. Ears close to the head, tense posture, and tail straight out from the body means “don’t mess with me.” Ears perked up, wriggly body and vigorously wagging tail means “I am sooo happy to see you!”

But there is another, newly discovered, feature of dog body language that may surprise attentive pet owners and experts in canine behavior. When dogs feel fundamentally positive about something or someone, their tails wag more to the right side of their rumps. When they have negative feelings, their tail wagging is biased to the left.

A study describing the phenomenon, “Asymmetric tail-wagging responses by dogs to different emotive stimuli,” appeared in the March 20 issue of Current Biology. The authors are Giorgio Vallortigara, a neuroscientist at the University of Trieste in Italy, and two veterinarians, Angelo Quaranta and Marcello Siniscalchi, at the University of Bari, also in Italy.

Research has shown that in most animals, including birds, fish and frogs, the left brain specializes in behaviors involving what the scientists call approach and energy enrichment. In humans, that means the left brain is associated with positive feelings, like love, a sense of attachment, a feeling of safety and calm. It is also associated with physiological markers, like a slow heart rate.

At a fundamental level, the right brain specializes in behaviors involving withdrawal and energy expenditure. In humans, these behaviors, like fleeing, are associated with feelings like fear and depression. Physiological signals include a rapid heart rate and the shutdown of the digestive system.

Because the left brain controls the right side of the body and the right brain controls the left side of the body, such asymmetries are usually manifest in opposite sides of the body. Thus many birds seek food with their right eye (left brain/nourishment) and watch for predators with their left eye (right brain/danger). In humans, the muscles on the right side of the face tend to reflect happiness (left brain) whereas muscles on the left side of the face reflect unhappiness (right brain).

Dog tails are interesting, Dr. Davidson said, because they are in the midline of the dog’s body, neither left nor right. So do they show emotional asymmetry, or not?

To find out, Dr. Vallortigara and his colleagues recruited 30 family pets of mixed breed that were enrolled in an agility training program. The dogs were placed in a cage equipped with cameras that precisely tracked the angles of their tail wags. Then they were shown four stimuli through a slat in the front of the cage: their owner; an unfamiliar human; a cat; and an unfamiliar, dominant dog. In each instance the test dog saw a person or animal for one minute, rested for 90 seconds and saw another view. Testing lasted 25 days with 10 sessions per day.

When the dogs saw their owners, their tails all wagged vigorously with a bias to the right side of their bodies, Dr. Vallortigara said. Their tails wagged moderately, again more to the right, when faced with an unfamiliar human. Looking at the cat, a four-year-old male whose owners volunteered him for the experiment, the dogs’ tails again wagged more to the right but in a lower amplitude. When the dogs looked at an aggressive, unfamiliar dog — a large Belgian shepherd Malinois — their tails all wagged with a bias to the left side of their bodies. Thus when dogs were attracted to something, including a benign, approachable cat, their tails wagged right, and when they were fearful, their tails went left, Dr. Vallortigara said. It suggests that the muscles in the right side of the tail reflect positive emotions while the muscles in the left side express negative ones.

While some researchers have argued that only humans show brain asymmetry — based on the evolution of language in the left brain — strong left and right biases are showing up in the brains of many so-called simpler creatures, said Lesley Rogers, a neuroscientist who studies brain asymmetry at the University of New England in Armidale, Australia. Honeybees learn better when using their right antenna, she said. Male chameleons show more aggression, reflected as changes in body color, when they look at another chameleon with their left eye. A toad is more likely to jump away when a predator is introduced to its left visual field (right brain/fear). The same toad prefers to flick its tongue to the right side when lashing out at a cricket (left brain/ nourishment).

Chicks prefer to use their left eye to search for food and right eye to watch for predators overhead, Dr. Rogers said. But when chicks are raised in the dark, they do not develop normal brain asymmetry. In trying to eat and watch for hawks overhead, such nonlateralized chicks become confused and vulnerable to attack.

Sheep, which are good at recognizing individual faces, use the right sides of their brains for knowing a Dolly from a Molly.

Chimpanzee brains are asymmetrical in the same ways as human brains, said William D. Hopkins, a researcher at the Yerkes National Primate Center and psychologist at Agnes Scott College in Atlanta. When chimps are excited, they tend to scratch themselves on the left side of their bodies, reflecting strong negative emotions, he said. And left-handed chimps are more fearful of novel stimuli than right-handers. Their dominant right brains may make them more cautious.

wow that is pretty cool. my dog's tail is docked though. so whenever it wags, his whole butt shakes, so it is hard to tell.

He is big and bulky but not fat, I just love him to pieces!!!

I got him through a breeder in Pennslyvania. He came with papers.

When we first saw him, I melted and then he ran after us on our way back to the car so I knew he was for us! When I got home and read the papers his mothers name was Golden Nugget. The golden my family had was also named Nugget so I had a sensational vibe about bringing him home. He is so awesome!

My brother took this picture a couple of years ago when I was asleep on the couch one afternoon.

Yeah he looks great, at least in that pic! IMO, too many American labs/goldens are too far from standard (taller and thinner). We get some GREAT looking labs at the shelter every so often, big massive dome heads, and people say they don't want it because it doesn't look pure. Um, hello?!

Do you know his club registered name?

Did anyone see Oprah yesterday?



Gibson isn't your average 5-year-old. He holds the Guinness record as the world's biggest dog! When measured in 2004, this Great Dane was 42 inches from his paws to his shoulders…but his owner, Sandy, says he's grown over an inch since then!

When Gibson is on his hind legs, he's 7'2"—that's an inch taller than NBA all-star Shaquille O'Neal.

Gibson's life isn't only about being in the spotlight. He knows the importance of giving back, so he volunteers as a licensed therapy dog. "His job is just to go around and make people happy and smile," Sandy says.



Now that you've met the world's biggest dog, meet the smallest. Brandy, a 3-year-old Chihuahua, is here with Jessica and her owners, Paulette and Brian.

Tiny Brandy is about the size of a candy bar—and not even a king-size one!

^ I saw this and left a comment about how horrible I thought it was and just having 100 dogs :blah blah: :blah blah: and someone emailed me to say don't think of it that way because they are working dogs and are treated differently than your house pet.

I still think you might be right. Sure, dogs live in packs, but a pack of 100? Where does that EVER occur in the wild? It would probably take a dozen Cesar Millan's working full time to properly maintain the social structure of a pack of 100 dogs.

I should probably watch the vid now, huh?

I believe with the AKC the breeders have to register the litter or they are not registrable. But registration only matters if the dog will be shown or compete in dog sports only for purebreds.

anitram, I can't see the picture, but I want to!
