New products to help train dogs for explosive detection

The Department of Homeland Security (USA) has been conducting independent assessments and developing products to assist canine explosive teams.

One of the biggest challenges in the training and testing of canine teams results from the explosives materials themselves – especially new homemade explosives. Due to the potential safety risks of explosives, only specially trained federal explosive technicians can provide the material for training and testing. This not only limits training times and opportunities, but also increases the costs since the technicians must travel to a central location for multi-day training events.

Researchers have been developing a new training aid that matches the scent of explosive materials but poses no danger to the trainers, the canines or the environment. It is currently undergoing field testing within federal, state and local canine detection teams. A key objective was to for the canines to react to the non-hazardous, non-explosive training aid the same way they would actual explosive material.

“It doesn’t go boom if you drop it, hit it or light it on fire,” said Canine Program Manager, Don Roberts. “That allows teams to take the training from the very controlled environment we currently have to train in for safety reasons and put it in a real-world scenario – for example putting the odor in a cinderblock and seeing if the dog can find it. We can put this new training aid in car wheel wells, airports etc., without fear that they’ll explode.”

S&T’s partner, Johns Hopkins Applied Physics Lab, developed the new training aid, Roberts said. After a number of trials, they’re ready to transfer the technology to the Transportation Security Administration, the primary customer for the aid. The bigger news, according to Roberts, is that the product was also designed to fit first responders’ needs as well.

“The design price point and usability factor has been geared to the first responder community – state and local explosive detection dogs who don’t have the regular training support TSA has. They are the ones who really need these products,” said Roberts.

The training aids are made to be thrown away after being used. These aids can last for over eight hours and can be stored up to two years. The scent can be dissolved in water, as opposed to the previous explosive training materials, which required special handling, transport and had to be stored in a bunker.

Next steps for this program include developing a second scent for training the dogs, and licensing so that the products can be produced outside of the federal government.

Doggy quote of the month for March

“It is the same with dogs as with children, if one wants them to be loved, they must be well brought up.”

– Madame Charles Boeswilwald, 19th century French author

Hear bark or C-Barq?

I’ve just signed Izzy up so we can complete a C-Barq questionnaire for her.

I know what you are thinking:  you don’t ‘see’ barks, you hear them.  Well actually, C-Barq stands for ‘Canine Behavioral Assessment and Research Questionnaire’ and it’s another example of citizen – or participatory – science.

Created by Dr. James Serpell who is a behaviorist at the Center for the Interaction of Animals and Society (CIAS) in Pennsylvania, the questionnaire is designed to provide dog owners and professionals with standardized evaluations of temperament and behavior.    The Center is based within the School of Veterinary Medicine at the University of Pennsylvania.

Tested extensively for reliability and validity on large samples of dogs of many breeds,  the current version consists of 101 questions describing the different ways in which dogs typically respond to common events, situations, and stimuli in their environment. It should take about 15 minutes to complete (I haven’t done this yet).

Please pay attention, however, to the sign-in page where questions are asked about your dog’s breed, background, and behavior.  This helps in coding the answers for analysis.

So far, over 80,000 dogs have been included in the study. Dr Serpell says, “There is no other breed or species of animal with such a wide variety of appearance and behavior.”

Between 10 percent and 15 percent of dogs can show very high levels of aggression, Serpell says, while 20 or 30 percent show no aggression.

Pit bulls and Akitas, popular breeds for fighting and guard dog duty, show serious aggression toward other dogs. But the title for most aggressive overall actually goes to tiny dachshunds, which display heightened aggression toward dogs, strangers and even their owners.

Animals in Emergencies – book review

AnimalsinEmergenciesCover

I have just finished reading Animals in Emergencies:  Learning from the Christchurch earthquakes by Annie Potts and Donelle Gadenne.  This was a must-read book for me.  Why?  I’m in it!

Published in late 2014, this book is largely a compilation of stories about people and animals caught up in the earthquakes of 2010 and 2011.  However, since it is also a text produced by university academics, it aims to serve a purpose as “an introduction to the specialised area of animal welfare management during emergencies.”

I found the first 90% of the book the most enjoyable.  Filled with stories of rescue, sheltering and individual owner’s tales of the earthquakes, the book serves to document – largely in the first person – the historical accounts of the days, weeks and months following the quakes.  And I like the fact that the book doesn’t just focus on companion animal dogs and cats, but also includes stories about horses, fish, hedgehogs and other species.

But the last 10% of the book is rather disappointing (and it hurts me to have to say this).  Since New Zealand is a production-based economy, this book had to focus on the fate of production animals.  But this is also where the book loses its tone and momentum.  Either the authors asked for interviews with farmers and researchers and were rejected, or they simply didn’t ask – we’ll never know.

Perhaps because of the lack of firsthand accounts, the book becomes too formal in its approach to describing the impact on farm animals and animals used in research.  The text uses citations from newspaper articles at this point and becomes ‘preachy’ in terms of animal welfare.  As someone with a personal interest in animal welfare management, the issues raised in the book are not new but the distinct ‘lessons learned from Christchurch’ is very much lost on the reader.

I’m pleased this book has been produced and I’m very honored to have my story told although I know that I’m a very small contributor to the overall efforts to assist animals following the quakes.

Animals in Emergencies has been distributed to booksellers worldwide and a paperback version is available on Amazon.com.

The migration of dogs in the Americas

A new study suggests that dogs may have first successfully migrated to the Americas only about 10,000 years ago, thousands of years after the first human migrants crossed a land bridge from Siberia to North America.

The study, which looked at the genetic characteristics of 84 individual dogs from more than a dozen sites in North and South America, is the largest analysis so far of ancient dogs in the Americas. The findings appear in the Journal of Human Evolution.

Unlike their wild wolf predecessors, ancient dogs learned to tolerate human company and generally benefitted from the association: they gained access to new food sources, enjoyed the safety of human encampments and, eventually, traveled the world with their two-legged masters. Dogs also were pressed into service as beasts of burden, and sometimes were served as food, particularly on special occasions.

Their 11,000- to 16,000-year association with humans makes dogs a promising subject for the study of ancient human behavior, including migratory behavior, said University of Illinois graduate student Kelsey Witt, who led the new analysis.

“Dogs are one of the earliest organisms to have migrated with humans to every continent, and I think that says a lot about the relationship dogs have had with humans,” Witt said. “They can be a powerful tool when you’re looking at how human populations have moved around over time.”

Human remains are not always available for study “because living populations who are very connected to their ancestors in some cases may be opposed to the destructive nature of genetic analysis,” Witt said. Analysis of ancient dog remains is often permitted when analysis of human remains is not, she said.

Previous studies of ancient dogs in the Americas focused on the dogs’ mitochondrial DNA, which is easier to obtain from ancient remains than nuclear DNA and, unlike nuclear DNA, is inherited only from the mother. This means mitochondrial DNA offers researchers “an unbroken line of inheritance back to the past,” Witt said.

The new study also focused on mitochondrial DNA, but included a much larger sample of dogs than had been analyzed before.

Autistic children who live with pets are more assertive

Yet another piece of research that points to the value of dogs and other animals.  This time the research was done at the University of Missouri and focused on the social skills of autistic children.

You guessed it – the children who lived with pets developed better social skills including assertiveness.  “When I compared the social skills of children with autism who lived with dogs to those who did not, the children with dogs appeared to have greater social skills,” said Gretchen Carlisle, Research Fellow.

Paleo-dogs ate reindeer

Perhaps not the most festive of postings for this time of year…but researchers from the University of Tübingen and the Senckenberg Center for Human Evolution and Paleoenvironment has revealed that dogs that lived 30,000 years ago ate reindeer as a staple in their diet.

Předmostí I is an exceptional prehistoric site located near Brno in the Czech Republic. Around 30,000 years ago it was inhabited by people of the pan-European Gravettian culture, who used the bones of more than 1,000 mammoths to build their settlement and to create ivory sculptures. Did prehistoric people collect this precious raw material from carcasses – easy to spot on the big cold steppe – or were they the direct result of hunting for food? This year-round settlement also yielded a large number of canids remains, some of them with characteristics of Palaeolithic dogs. Were these animals used to help hunt mammoths?

To answer these two questions, Tübingen researcher Hervé Bocherens and his international team carried out an analysis of carbon and nitrogen stable isotopes in human and animal fossil bones from the site. Working with researchers from Brno and Brussels, the researchers were able to test whether the Gravettian people of Předmostí ate mammoth meat and how the “palaeolithic dogs” fit into this subsistence picture.

They found that humans did consume mammoth – and in large quantities. Other carnivores, such as brown bears, wolves and wolverines, also had access to mammoth meat, indicating the high availability of fresh mammoth carcasses, most likely left behind by human hunters.

Surprisingly, the dogs did not show a high level of mammoth consumption, but rather consumed essentially reindeer meat that was not the staple food of their owners. A similar situation is observed in traditional populations from northern regions, who often feed their dogs with the food that they do not like. These results also suggest that these early dogs were restrained, and were probably used as transportation helpers.
