Why Do Dog Breeds Look Like That?


From the Dachshund's stubby legs to the Shar-Pei's wrinkly skin, breeding for certain characteristics has left its mark on the dog genome. Researchers have identified 155 regions on the canine genome that appear to have been influenced by selective breeding.
With more than 400 distinct breeds, dogs come in a wide range of shapes, sizes, fur-styles, and temperaments. The curly-haired toy poodle, small enough to sit in a teacup, barely looks or acts like the smooth-coated Great Dane tall enough to peer like a periscope out of a car's sunroof. Not so apparent are breed differences in how the dogs' bodies function and their susceptibility to various diseases.

Although domestication of dogs began over 14,000 years ago, according to Dr. Joshua Akey, University of Washington (UW) assistant professor of genome sciences, the spectacular diversity among breeds is thought to have originated during the past few centuries through intense artificial selection of and strict breeding for desired characteristics. Akey is the lead author of the effort to map canine genome regions that show signs of recent selection and that contain genes that are prime candidates for further investigation. Those genes are being examined for their possible roles in the most conspicuous variations among dog breeds: size, coat color and texture, behavior, physiology, and skeleton structure.

The researchers performed the largest genome-wide scan to date for targets of selection in purebred dogs. The genomes came from 275 unrelated dogs representing 10 breeds that were very unlike each other. The breeds were: Beagle, Border Collie, Brittany, Dachshund, German Shepherd, Greyhound, Jack Russell Terrier, Labrador Retriever, Shar-Pei, and Standard Poodle.

The study was conducted, the researchers said, because the canine genome, the product of centuries of strong selection, contains many important lessons about the genetic architecture of physical and behavioral variations and the mechanisms of rapid, short-term evolution. The findings, the researchers said, "provide a detailed glimpse into the genetic legacy of centuries of breeding practices."

Dogs Teach Kids To Read (Yup, You Read That Right)

Meet Bailey. She's a registered therapy dog, but you won't find her in hospitals or nursing homes. Instead, Bailey makes weekly visits to libraries and schools. She sits quietly or snuggles up to kids as they read her a book. And no, she's not napping, and the kids don't have treats in their pockets. She's actually helping these children learn to read.

It sounds implausible. After all, dogs can't read. How could they possibly help someone learn a skill that they themselves can't grasp? But it's a growing trend, and it seems to be working.

The philosophy is simple. Children who are just learning to read often feel judged or intimidated by classmates and adults. But reading to a dog isn't so scary. It won't judge, it won't get impatient, it won't laugh or correct if the child makes a mistake. In a nutshell, dogs are simply excellent listeners. And for shy kids or slow readers, that can make all the difference.

Kathy Klotz is executive director of Intermountain Therapy Animals, which runs a nationwide program called R.E.A.D. -- Reading Education Assistance Dogs. She says there's another benefit of reading to the dogs that she didn't anticipate: confidence.

"A factor that we never planned for, that turned out to be really important, is that the child feels like they're letting the dog understand the story," she says. "They get to be the teacher, the storyteller, the one who knows more than the dog for a change. ...They just blossom when they get to be the one who knows more than the dog."

The children know they're not actually teaching the dog, of course, but the for the kids, the idea that they know more than the dog and can share their knowledge is a powerful one. And now that volunteers are aware of that aspect, Klotz says they actively foster the idea of the child as the teacher.

"One of the things you do in the program is you always speak for the dog," says Klotz. "Like if [the child] doesn't know a word, the dog doesn't know the word either. And then they're not alone, and they can look it up in the dictionary together."

Ithaca Pioneers Dog Waste Composting


Several years ago, dog owners in the college town of Ithaca, N.Y., began worrying about all the plastic bags filled with dung that ended up in the landfill.

Leon Kochian, a professor of plant biology at Cornell and, more to the point, the owner of a yellow lab, recalled the thinking at the time: “This is Ithaca. There’s got to be a more environmentally sensible way to do this.”

This year, with Mr. Kochian’s nudging, one of the city’s dog parks — part of the Allan H. Treman Marine State Park — became a dog waste composting park.

Special corn-based bags, made by the Biobag Company, based in Florida, are available at several stations in the park. Dog owners put the bag and its contents into large bins near the park’s entrances, which are removed once a week by a company called Cayuga Compost.

At its composting facility, Cayuga dumps the waste into a pile — mixed with a bit of yard and wood waste — quite separate from the company’s regular food-waste compost.

And there it will sit — until the company figures out what it might be good for.

Late next year, Cayuga plans to run tests to determine the composition of the dog waste (after all, a dog’s diet is arguably more varied than virtually any other animal’s, in accordance with the whims of their owners). If it matures into nutrient-rich compost, it might be applied to potted plants or landscaping, said Mark Whittig, Cayuga’s operations manager. If the compost is of poorer quality, it could be used for blending with topsoil, he said.

Clifford the Big Red Dog at Cincinnati Museum Center

Whoever said learning wasn't fun has yet to visit the new Adventures with Clifford the Big Red Dog Exhibit at the Cincinnati Museum Center. Children won't even realize they are learning as they wander through nine interactive playgrounds, each themed around one of "Clifford's Big Ideas."

Clifford's big ideas are designed to teach children 10 simple life lessons ranging from sharing to respsonsibility. "It's all educationally based," said Dougless McDonald, president and CEO of the Cincinnati Museum Center. "As children enjoy themselves in the exhibit, they will be learning topics important for child development."

So what brought this educational exhibit to the tristate area? Well, the Duke Energy Children's Museum is celebrating the 10th anniversary of its move to the Cincinnati Museum Center. While the celebration today was only open to musuem members, the Adventures with Clifford the Big Red Dog Exhibit opens to the public Oct. 4 and is scheduled to run through Jan. 11.

Dogs Trained for Hearing Impaired

China's first center for training hearing dogs for deaf people will be set up at Beijing Union University with financial support from Samsung, an official partner of the 2008 Paralympics, a spokesman for the firm said Thursday on the sidelines of the Games.

Park Keun-hee, president of Samsung China, said the company will donate 1.4 million yuan ($200,000) to establish the facility at the university, where more than 300 students with hearing problems are following courses in higher education.

He did not say when the center would open. The center will, however, be one of only a handful in existence around the world. Similar facilities exist in the US, the UK, Japan and South Korea, Park said. The center in South Korea was set up in 1993, and since then has trained 650 "assistant dogs" for a variety of people including the blind, the deaf and police officers, he said.

"Staff at the Samsung Assistant Dog Service Training Base in South Korea have a lot of experience in training dogs, and we hope to bring that knowledge to China to provide long-term support for deaf people here," Park said. The dogs, many of which are former strays, are provided free of charge. Samsung will provide financial support for the center's first three years of operation, he said.

Hearing dogs are trained to distinguish between different types of sounds, such as a telephone ringing, a knock at the door or a fire alarm. They then "touch" a specific part of their owner's body to indicate the particular sound. The Beijing center will train four dogs per year in the beginning, with the number growing over time, Park said.

Although China has more than 20 million people with hearing problems, there are just three hearing dogs working in the country, two of which were provided by Samsung in 2006 to two students at Beijing Union University. Dong Shan, one of the dogs' owners, said: "I've had my dog for over two years now, and it has become my close friend. "It has made my life much easier."

China's third hearing dog, also donated by Samsung, was presented Thursday to Qi Daxin, a deaf man living in Beijing. "Getting this dog in my 50s is great," the 53-year-old said using sign language. "It will help me to become more integrated in society."

A Dog's Amazingly Large Vocabulary

Be careful what you say around your dog. It might understand more than you think. A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to learn words for new objects as easily as a 3-year-old child would. Its word-learning skill is as good as that of a parrot or chimpanzee.

Rico knows the meaning of a surprisingly large number of words. In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them randomly into 20 sets of 10 objects each. The dog waited with one of his owners in one room, while an experimenter put a set of 10 objects into another room. Then, the owner told the dog to fetch one of the items. The dog had to go to the other room and bring the object back.

In four trials, Rico got 37 out of 40 commands right. Because the dog couldn't see anyone to get visual clues about what to bring back, the scientists concluded that he must understand the meanings of certain words.

In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names he already knew. The dog's owner then told him to fetch the object, using a word Rico had never heard.

In 7 out of 10 trials, Rico picked the right object, suggesting that he figured out the answer by process of elimination. A month later, he remembered half of the new names, which further impressed the researchers.

Rico is probably smarter than the average dog, the scientists say. For one thing, he's a border collie, a breed known for its mental abilities. In addition, the 9-year-old dog has been trained to retrieve toys by their names since he was 9 months old.

It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your pup every now and then. You might just get a big, wet kiss in return!

Praise Your Dog

The key is that dogs need to believe our praise. Dogs are very emotional and very perceptive. As pack animals, they seek the approval of their superiors. If other people see you praise your dog, and they think you're pretty weird, then you are probably praising it correctly.

Gush over the dog: Talk to the dog. Tell him how well he just sat; how nice and straight it was; how snappy and confident it was done. Tell him how you admire his cleverness and intelligence, and how you appreciate his good work. Say it from the heart. Mean it. Say it as silly and as babyish as you need to, to get the dog's eyes to brighten up, his posture to rise, his ears to perk up proudly. That is praise.

If the boss called you ...: If your boss called you into the office and said, "You're doing good work. Now get out of my office and get back to work!!" you probably would feel more hurt and angry than anything else. But, if he sat you down for a few minutes and told you just how and where you were doing well, you might get some good feelings. It is these good feelings that we must give our dogs when we praise them.

Praise can never be a mechanical reaction to the dog performing correctly. It must be a genuine expression of joy and satisfaction. How else can a dog understand what to do? Working simply to avoid getting a jerk on the leash is a miserable existence. A dog knows it is doing the right thing when it feels loved and appreciated for doing it.

Study and learn: If you can't tell when your dog feels loved and appreciated, you must study your dog more closely, and build a much better rapport. Take long walks. Do very brief obedience and other exercise with lavish amounts of vocal praise, and very little excitement and play. Talking more to your dog, relying on your intonation and facial expression, will build his understanding of praise.

Tossing a ball or a stick for your dog is not praise. It is play. It is important to play with your dog. But, if your dog doesn't feel good from your vocal praise and your facial expression, all the play in the world will not build a relationship, nor will it help you in training.

The best communication: The best way to develop a good relationship with your dog is to communicate on an emotional level. You must rely on building your skill at talking to the dog, so that the dog picks up immediately on your emotions.

It is easy for most people to talk silly with puppies. It takes some practice, and little concern for your ego, to be able to talk babyish to a big, tough dog. Since we cannot elevate the dog to human understanding, we must act in ways that dogs understand. A pat on the side and a "good boy" can give great satisfaction and release to the dog.

Teaching Your Dog to Swim

Swimming seems so integral to being a dog that we’ve even named a stroke after them, the dog-paddle — so you’d assume that’s something that every dog is born knowing how to do. It turns out that you’d be wrong. Not every dog knows instinctively how to swim, and some can’t swim at all, Wendy Diamond, the founder and editorial director of Animal Fair magazine, told TODAY. Dogs’ aquatic abilities are so misunderstood, in fact, that she put together a list of water safety tips for dog owners.

Diamond confirmed that some dogs are born swimmers. It’s a good bet if the dog’s breed includes the word “water,” as in Portuguese or English water spaniel, it takes to swimming like a nursery-schooler takes to finger-painting. For owners of those breeds, the problem isn’t getting the dog into the water, but keeping it on dry land.

But other breeds aren’t as water-friendly. Some dogs have to be taught to swim, Diamond said, and others, like bulldogs, take to the water like submarines take to the Cross Bronx Expressway. For the former, there is hope. For the latter, there are those bright orange canine flotation devices. Among those that can’t swim at all or swim only with great difficulty are basset hounds, bulldogs, dachshunds, pugs, corgis, Scottish and Boston terriers and greyhounds.

And then there are dogs like the Maltese, which are capable swimmers, but which are also susceptible to rheumatism, arthritis and chills that could be exacerbated by taking them in the pool with you. Diamond has a checklist for doggy swim lessons:

Avoid excessive noise: “Take them to an area that’s not so crazy and hectic,” she advised. Like children, dogs can become frightened and confused if there’s a lot of noise and activity around them. The object is to keep them calm and focused on the swimming lesson.

Use encouragement: As when teaching a child, keep your voice upbeat and positive, she said. “Using treats and toys to encourage your dog to enter the water also works quite well,” she said.

Never throw them in: Just as you shouldn’t throw a child in the water and expect it to swim to safety, you shouldn’t do that with a dog, Diamond said. “Don’t force the dog. If they don’t want to do it, don’t force them to do it.” Instead, she told Celeste, “Slowly put them in the water and get their paws used to it.”

Support their weight until they paddle: Even if the dog is wearing a life vest, Diamond said, support its midsection and hindquarters in the water until they start paddling and feel comfortable.

Show them how to get out: Getting a dog in the pool is only half the battle. Diamond reminded pet owners that they also need to be shown where the steps are in the pool so they can easily get out.

Keep an eye on them: Even in the water, dogs can wander off. Dogs that swim naturally and well can jump in the ocean and keep swimming until they’re lost, Diamond said. “You want to make sure, like children, that you watch where they’re going,” she said.

Their First 'Baby' Was a Dog; How Will It Handle the Real Deal?



Some interesting info on training your pet to deal with your family's new arrival.

Dogs Provide an Ear, Tool for Reading

In one hand is a book. While the other hand gently pets a therapy dog. Students at Curtsinger Elementary School in Frisco are practicing reading out loud, but with a twist. Instead of reading to classmates, they're reading to dogs. "They can hear you and they listen," says Zachary Guerrero, a third grader. Listening is the key.

"It's given him a lot more confidence because when he reads with the dog, the dog doesn't correct him, where when he reads with me I tend to correct," says Donna Guerrero, Zachary's mother. "He's more excited to read."

Zachary says reading to the dogs is simply fun. He says he's reading more and wants to come spend time with the dogs. "You get to read to the dogs and they listen to you and you get to sit by them and they are very soft," he says.

Curtsinger began the new after school program this month. It was developed by teacher Diane Gossett, a therapy dog owner. Volunteers from Heart of Texas Therapy Dogs bring their certified dogs each Thursday.

"Fortunately the administrators in our school are also dog lovers and animal people, so they were open to the concept," Gossett says. It's a concept that's been used in schools and libraries across the country for a few years, but Gossett believes Curtsinger is the first school in this area to use the reading dogs.

"I do know the power that animals have with kiddos," says Principal J'Lynn Anderson. The program works to make reading out loud more comfortable for these children, who often struggle in front of their classmates. "You can see the confidence on the kiddos face, that unconditional love, there's not a threat there, there's no stress," Anderson says. "They're just enjoying reading their books with a pal."

Twelve students are in this pilot, five-week program. The changes, teachers and parents say, are clear. "We have seen children that don't normally talk a lot, open up," Gossett says. "We've seen self confidence increase."

"Just being with the dogs, it just makes him feel calm and excited," Donna Guerrero says. "And they don't judge him when he reads. They just listen." Parents like Guerrero hope the program will lead to the children reading more, not only to the dogs, but eventually in class and beyond. "We want to them to perform a certain way, but with the dogs they just accept them the way they are and so they encourage them to read more," she says.
