(Press-News.org) One in four dogs competing in the world's largest canine show (Crufts) is overweight, despite the perception that entrants are supposed to represent ideal specimens of their breed, reveals research published online in Veterinary Record.
The widespread dissemination of show dog images online may be 'normalising' obesity in dogs, now recognised to be a common canine disorder, say the researchers.
As in people, obesity in dogs has been linked to orthopaedic problems, diabetes, respiratory disease, and certain types of cancer. It also affects both the quality and length of a dog's life.
The researchers base their findings on 1120 online images of dogs from 28 breeds---half of which are prone to obesity--that had appeared at Crufts. This is the UK's national dog show, and the largest of its kind in the world.
Only adult dogs that had been placed between first and fifth in their class between 2001 and 2013 were included in the study.
The images were coded and anonymised, and 960 were suitable for assessment. A second person then graded the body condition of each dog in one sitting, using a previously validated method.
Three out of four (708; 74%) of the show dogs were in ideal condition, and none was overweight. But one in four (252; 26%) was overweight.
Pugs, basset hounds, and Labrador retrievers were the breeds most likely to be assessed as being overweight. Dogs were overweight in 80% of the pug images, and in around two thirds of the basset hound (68%) and Labrador (63%) images.
The three breeds with the highest prevalence of overweight among the online images are prone to excess weight. But, given that pugs were originally bred to be a companion dog, while hounds and Labradors were bred, respectively, for hunting and fieldwork, being overweight would not be advantageous, say the researchers.
Standard poodles, border terriers, Rhodesian ridgebacks, Hungarian vizlas and Dobermanns were the least likely breeds to be overweight.
The researchers point out that the prevalence of overweight among the show dogs was less than that reported generally for pet dogs in the UK. But the fact that "a quarter were above ideal weight is still a cause for concern," they write.
"These dogs showcase the ideal characteristics of the pedigree breed, and there is a danger that widespread media exposure might adversely influence owner perception of optimal body shape," they say.
The Kennel Club has recently introduced changes in policy for judging criteria, to emphasise characteristics that promote good health in dogs, say the researchers.
But breed standards of optimal condition should be reinforced for competition, to ensure consistency, they say, concluding: "Further effort is now required to educate owners, breeders and show judges so that they can all better recognise overweight condition, thus helping to prevent the development of obesity."
INFORMATION:
One in four dogs competing at Crufts is overweight, researchers at the University of Liverpool have found.
The competition is the largest show of its kind in the world, showcasing the best physical and behavioural qualities in a variety of canine breeds. Research, published in the Veterinary Record, however, reveals that up to 26% of some of the best show dogs, such as pugs, Basset hounds, and Labrador retrievers, are actually overweight.
The team studied more than a 1,000 images of 28 dog breeds that had been placed between first and fifth in their class during ...

PHILADELPHIA -Patients over 50 with ulcerative colitis (UC), a chronic disease of the colon, who undergo surgery to treat their condition live longer than those who are treated with medications, according to a new study from the Perelman School of Medicine at the University of Pennsylvania. The results are published this week in Annals of Internal Medicine.
"Ulcerative colitis is a chronic disease that most physicians opt to treat with medications, as opposed to surgery," said the study's lead author Meenakshi Bewtra, MD, PhD, MPH, assistant professor of Medicine and ...
In preliminary research, a small number of occult (hidden) malignancies were subsequently diagnosed among pregnant women whose noninvasive prenatal testing results showed chromosomal abnormalities but the fetal karyotype was subsequently shown to be normal, according to a study appearing in JAMA. The study is being released to coincide with its presentation at the 19th International Conference on Prenatal Diagnosis and Therapy in Washington, D.C.
Understanding the relationship between aneuploidy detection (an abnormal number of chromosomes) on noninvasive prenatal testing ...
Boulder, Colo., USA - Super-eruptions are not the only type of eruption to be considered when evaluating hazards at volcanoes with protracted eruption histories, such as the Yellowstone (Wyoming), Long Valley (California), and Valles (New Mexico) calderas. There have been more than 23 effusive eruptions of rhyolite lava at Yellowstone since the last caldera-forming eruption ~640,000 years ago, all of similar or greater magnitude than the largest volcanic eruptions of the 20th century.
This study by Christy B. Till and colleagues is innovative because it is the first ...
DURHAM, N.C. - Practically everyone gets fatter as they get older, but some people can blame their genes for the extra padding. Researchers have shown that two different mutations in a gene called ankyrin-B cause cells to suck up glucose faster than normal, fattening them up and eventually triggering the type of diabetes linked to obesity.
The more severe of the two mutations, called R1788W, is carried by nearly one million Americans. The milder mutation, known as L1622I, is shared by seven percent of the African American population and is about as common as the trait ...
CHICAGO-- The use of 3D printers has the potential to revolutionize the way food is manufactured within the next 10 to 20 years, impacting everything from how military personnel get food on the battlefield to how long it takes to get a meal from the computer to your table, according to a July 12th symposium at IFT15: Where Science Feeds Innovation hosted by the Institute of Food Technologists (IFT) in Chicago.
The price of 3D printers has been steadily declining, from more than $500,000 in the 1980s to less than $1,000 today for a personal-sized device, making them increasingly ...
CHICAGO-- Dr. Mark J. Post is confident his recipe for his $300,000 cultured hamburger will not only come down in price but someday make it to market, according to a July 12th presentation at IFT15: Where Science Feeds Innovation hosted by the Institute of Food Technologists (IFT) in Chicago.
"It's realistic that we can do this," said Post, chair of the department of physiology and professor of vascular physiology and tissue engineering, Maastricht University, The Netherlands, who is refining what he already sees as a patty consistent in look, texture and color to a traditional ...
CHICAGO-- Algae is evolving as the next new alternative protein source consumers are anxious to bite into as an ingredient in crackers, snack bars, cereals and breads, according to a July 12th presentation at IFT15: Where Science Feeds Innovation hosted by the Institute of Food Technologists (IFT) in Chicago.
Algae, quinoa and pulses are considered by some food technologists to be the best protein sources and strong alternatives to slow meat consumption, reduce food waste and help feed the world's growing population.
Algae is a new vegan source of protein with a comparable ...
ANN ARBOR - The first computer model that predicts the flow of liquid medication in human lungs is providing new insight into the treatment of acute respiratory distress syndrome.
University of Michigan researchers are using the new technology to uncover why a treatment that saves the lives of premature babies has been largely unsuccessful in adults.
Acute respiratory distress syndrome, or ARDS, is a life-threatening inflammation of the respiratory system that kills 74,000 adults each year in the United States alone. IIt's most common among patients with lung injury ...
