The Patron Saint of Lost Dogs – book review

Patron saint of lost dogs

In this first novel by Dr Nick Trout, the main character – Dr Cyrus Mills – returns to his hometown to run the veterinary practice of his late father.  Already in financial difficulties himself, Cyrus finds the the practice is also in dire straights and the local banker has given him a week to come up with a good faith payment on debt.

On his first day in the practice, he meets a Golden Retriever named Frieda whose owner wants her to be put down because she is having accidents in the house.  Frieda becomes something of a stowaway in Cyrus’ apartment as “Missing Dog” posters start appearing around the town featuring Frieda, whose full name is Frieda Fuzzypaws.

Then there are the other characters that make up the story.  The x-ray of a Persian cat with digestive problems reveals that the owner’s fiancee isn’t as doting and devoted as he seems.  An elderly female dog named Clint (one in a long line) tests Cyrus’ ability to work with emotional owners and brings him closer to his own love interest, a local waitress.

Clearly Dr Trout has used his own veterinary background to make this story realistic and, hailing from New England himself, he’s used a small Vermont town in winter as the setting for the story.

I enjoyed this novel.  I wouldn’t say I loved it – but it’s a good one for taking on vacation with you to the beach.

And you have to find out what happens to Frieda Fuzzypaws!

I’ve also reviewed Tell Me Where It Hurts by Dr Trout.  Read my review here.

How dogs detect explosives

A research team at Indiana University-Purdue University Indianapolis (IUPUI) has helped determine the science behind how dogs locate explosives such as Composition C-4 (a plastic explosive used by the U.S. military). The study found the dogs react best to the actual explosive, calling into question the use of products designed to mimic the odor of C-4 for training purposes.

These findings are the culmination of a four-year contract funded by the U.S. Department of Defense (DOD).

“Appropriately, dogs that are trained to find real explosives are going to find real explosives and not much else,” said John Goodpaster, Ph.D., associate professor of chemistry and chemical biology and director for the Forensic and Investigative Sciences Program in the School of Science at IUPUI.

The effectiveness of trained detector dogs is well established, but the study sought to determine which chemical compounds cause a dog to recognize a particular explosive and alert to it. Previous studies have suggested that certain non-explosive chemicals emitted by Composition C-4 cause dogs to alert, and that these specific chemicals could be used as mimic substances to train the dogs in place of real explosives.

The research team discovered that the non-explosive chemicals given off by C-4 mimics also are present in a variety of everyday plastic objects. Objects tested included PVC pipes, electrical tape, movie tickets, a plastic grocery bag and plastic food wrapping. Several of the tested items emitted appreciable levels of a mimic compound recommended by some vendors for training dogs.

The second phase exposed 33 trained canines from the DOD, Department of Justice, Amtrak and other agencies to these vapors to see if the dogs would respond. The field trials demonstrated that the dogs failed to respond in any significant way to specific odor compounds found in C-4. The results indicate that if the dogs are trained on the full scent, they will only detect real explosives.

The study findings have been published in the March 2014 edition of the journal Forensic Science International.

How dogs were trained for functional MRI research

I’m an absolute advocate for positive reinforcement training.  Here’s how Professor Gregory Berns and his research team trained dogs to remain still in a noisy MRI scanner.

Singing in the rain

It’s raining and blowing a gale in Christchurch today.  So I thought I’d share this little video to cheer everyone up!

 

Understanding what is higher value

Researchers have now proven what dog trainers have known for some time: dogs have a sense of quality when it comes to treats and they will seek out the higher value ones.

Kristina Pattison and Thomas Zentall of the University of Kentucky tested the principle by feeding baby carrots and string cheese to ten dogs of various breeds

Dog eating cheeseThe research was conducted on dogs that would willingly eat cheese and baby carrots when offered, but showed a preference for the cheese. However, when given a choice between one slice of cheese, or the cheese together with a piece of carrot, nine of the ten dogs chose the cheese alone. That is, they chose less food over more food.

People, for instance, tend to place greater value on a set of six baseball cards that are in perfect condition, than on the same set of six perfect cards together with three more cards in fair condition.

In cases where rapid decisions must be made, quick solution-driven heuristics such as the “less is more” effect may come in handy. For instance, it is helpful when members of the same species, such as a pack of dogs, feed together. The one that hesitates may lose food to faster-choosing competitors.

But the fact that one in ten dogs did choose the cheese-and-carrot combination suggests that levels of motivation may play a role in this effect. The outlier dog, for instance, had a history of living in shelters and fending for himself.

The puppy and the magpie

Just received this link from a friend – a cute puppy and an Australian Magpie playing in the yard. Great pals.

Happy Friday!

The Duchess and the Wolfhound

This week, the Duchess of Cambridge visited the Irish Guards to present sprigs of shamrocks to the regiment’s members. That included Domhnall, the Guards’ mascot. Domhnall is an Irish Wolfhound (how appropriate!)

What is it about dogs and car advertising?

The folks at Land Rover are using a black Great Dane in their latest ad for the Range Rover Evoque:

What is it about using dogs in car advertising?  I think it is that most dogs enjoy car travel and being in the company of their family whether it is running the weekly errands or on a family vacation.

What do you think?
