2015: Puppy New Year! Get some science into your dog

2015 is a bright and shiny new year for canine science! 

But first, this face:

After being a dog-less household for eight months (you might remember we sadly farewelled Elke in 2013 and gut-wrenchingly, also old man Caleb, in the first half of 2014) we welcomed a new member to the family at the end of 2014. 

Those paws. Not photoshopped.
If I'm honest with you, I'd been stalking PetRescue quietly for a month or so, not really sure if the time was right, but also open to being inspired to make it the right time to welcome a new dog into our lives. I eventually made a call to a shelter a long, long way away about a dog I'd seen who looked like the kind of dog I thought would be a good fit for our family over the next fifteen years. His profile had been up for a few weeks and I was concerned he might be nearly out of time to be adopted. The lovely shelter staff let me know he'd actually just been adopted that morning - I was thrilled for him and his new family. Probably a good thing anyway, that shelter was 5 hours' drive away - no small distance. 

The following day I received a message from the shelter staff - there was another dog - a younger pup, similar type, would I be interested? "Send me some photos and a video clip of him" I said... and they did. I told Julie about the pup and how far away he was. "Love this story!! Keep it coming ;)" she said via email. Huh, I thought - what an adventure this could be to meet a new family member - and luckily, my partner agreed!

So a week later, coincidentally on my birthday, we headed off after lunch on a 400km (that's 250miles to those of you who prefer miles) drive to a faraway coastal town south west of Melbourne to meet this four month old pup. He had come into the regional shelter as a stray. Whether he was deliberately dumped, wandered off through an open gate, or actively strayed by jumping a fence - we'll never know. That's part of the shelter dog story - not necessarily knowing what came before. 

What we do know is this: 
  • He was not identified by microchip, had no collar with ID and was not desexed
  • No one came looking for him during his two weeks in the shelter
  • On meeting us, he was excitable, mouthy and jumpy, but calmed down fairly quickly
  • We have named him Rudy (roo-dee), inspired by Rudolph as it was Christmas week


What is he?
We've been asked that a lot! Rudy is a Staghound. Staghounds in Australia are similar to Lurchers and Longdogs in the UK - a 'type' of dog, rather than a breed. Staghounds are generally greyhound x deerhound with maybe a bit of whatever else was around the area in them too. They can vary widely in looks as they are bred with an emphasis on health, performance and longevity, rather than to a physical standard. They are generally bred to help with hunting in rural areas, but like greyhounds, can make excellent companions as well. As you'd expect, they are highly distracted by moving things.

A diet of science
Inevitably, we're feeding Rudy a daily dose of science. If you want to keep up with how he's going, you can follow the #RaisingRudy hashtag on Twitter, keep up with our Do you Believe in Dog? Facebook posts, or check in here at the blog for regular updates. I've never claimed to be a dog trainer, but I'm certainly aware of the importance of putting the wide array of scientific findings into practice with our dogs to help them have a great life and help us enjoy our time with them.

So far, over the first couple of weeks Rudy's been with us, this has looked a bit like this:
In these early days, we're focusing on socialisation (new experiences, places, people, surfaces, sounds, smells), basic training (toilet training, recall, sit, leash walking, house behaviour, independent time outside) and getting to know Rudy (learning how he responds to new places, loud noises, other dogs and people, etc.). We're marvelling at those ears. 

We're remembering what having a puppy in the house means (e.g. encouraging the puppy to splash its feet in a toddler pool is super funny and cute, until it starts repeating that behaviour in the indoor water bowl and floods your laundry!). We're a tidier household for it (Shoes go in cupboards! Pre-schooler's toys get put away! Remote controls go up high!).

If, like us, it's been a while since you raised a puppy, you might enjoy the back seat experience (sometimes hilarious, sometimes frustrating!) offered by the new BBC documentary series 'Six Puppies and Us' - Episode 1 linked here:

Why do dogs lick people?

It started with a question on twitter, and turned out to be our most popular post of 2014.
With the photo by Chris Sembrot that can not be unseen, this post from Mia looked at what we have learned about why dog lick us - there's no one quick answer and some people were quite surprised at the depth of background, in evolutionary, social and environmental terms, behind what we consider an everyday behaviour. A big part of why we love canine science!

Cat and Dogs: seeking solutions with sniffing canines and science

Hi Mia and Julie, 


First of all, I LOVE your blog! 

After meeting at SPARCS this past summer (summer for us in North America.. I take it summer is just beginning in Australia!), I’ve followed it closely. 

You do amazing things for the promotion of  canine science. Serious love.

A bit of background for the readers: I’m currently doing my PhD at Dalhousie University in Halifax, Nova Scotia in Canada, under the supervision of Dr. Simon Gadbois

Dr. Gadbois has an amazing amount of knowledge and experience in the science of sniffing (just check out Gadbois & Reeve, 2014 link below!). 

He’s trained sniffer dogs for the conservation of ribbon snakes and wood turtles, to track coyotes, and to detect invasive pests in lumber. He and I have taken on a different type of project and are studying the intricacies of biomedical detection dogs, specifically, the very interesting phenomenon of Diabetic Alert Dogs

Cat Reeve at #SPARCS2014 where she won the 'Best Emerging Researcher' prize

I say interesting because there’s anecdotal evidence suggesting that some dogs alert their owners to hypoglycemic events (low blood sugar). In 2008, Deborah Wells published a series of case studies where dogs were reported as signalling (barking, licking, pawing etc. the individual) while their owners were awake, while they were sleeping, and even when their owners were in a different room with the door closed! And this is with no previous training! 

Isn’t this fantastic! Severe hypoglycemic events can be extremely dangerous for individuals with diabetes. If not treated, they can lead to seizures, comas, and even death. The fact that dogs may be able to alert an individual before a serious hypoglycemic event means less worry about hypoglycaemia unawareness, and blood sugar dropping over night when individuals are unconscious.


Given that dogs are signalling through closed doors, it is assumed that the dogs smell something that alerts them to a change in the physiology of their owner (as opposed to behavioural cues, as is believed to be the case with seizure alert dogs). There are many companies that have taken advantage of this supposed ability, and have trained Diabetic Alert Dogs (DADs) to sell to individuals with diabetes. 

In my own searches, I have found no company that publicly provides information as to how they train their dogs. However, according to recent studies (see Gonder-Frederick et al., 2013 and Rooney et al., 2011 below) these trained DADs dogs contribute greatly to the families of individuals’ with diabetes; they signal consistently and, consequently, significantly reduce the number of hypoglycemic events an individual experiences. 

Now, if it is in fact an olfactory cue that dogs use to identify a drop in blood sugar in their owners, one would expect that if you presented one of these trained DADs with the “scent” of hypoglycemia without the individual present (just like having the owner with diabetes on the other side of a door), the dog would still signal. 

Dehlinger and colleagues recently tested three DADs in a lab setting, presenting the dogs with human biological samples that were obtained identically to the way the samples used to train the dogs were obtained. In this study, none of the three dogs could pick out a hypoglycemic sample from a normoglycemic sample! DARN!

So what is it that these dogs smell? How is it that some DADs are accurate at signalling hypoglycaemia but evidently cannot signal in the lab? 

Enter ME! This is what I’m trying to figure out!

One possibility is that, at least in the study outlined above, the use of sweat samples was misguided. Maybe the volatiles are more strongly present in an individual’s breath. I am currently in the process of testing whether there is one channel more likely than others to expel the volatiles needed to detect a change in blood sugar, i.e. breath, sweat, or saliva. 

So far we’ve found that, after being trained to detect extremely low saliency scents, our dogs can detect and discriminate between human breath samples with incredible ease and accuracy (see the video of Koda discriminating between breath samples). 


Little Koda discriminating between breath samples. The jar that has the check mark on it is the target sample. The jar with the x+ is a different breath sample. When Koda first enters the room, he smells a jar that is the “sample” (it matches the target sample)... This is the smell we want him to find amongst the three jars that are closer to the camera. He chooses the right one!

Preliminary tests with patient samples suggest that our dogs can also tell the difference between breath samples taken from the same individual when their blood sugar was low, when it was normal, and when it was high (unpublished). 

Also, it’s possible that in the Dehlinger et al. (2013) study, the sample collection procedure was simply not sufficient enough to contain the volatiles produced during a hypoglycemic event. With the help of a fantastic chemist at Dalhousie (Dr. Peter Wentzell), we have perfected a procedure that coats cotton balls in silicone oil. This is believed to help contain the volatiles through the *magic of chemistry.  

*may actually be science, not magic - check with the chemists

Another potential is that these DADs are simply responding to a general stress response in the body. It’s possible that DADs (and untrained dogs who signal to their owners) are picking up on the physiological change associated with stress (changes in cortisol, adrenaline etc.). Kind of how people say animals can smell when you’re scared. 

If this is truly what’s happening, you would expect to see DADs giving a lot of false alarms. 

And in fact, personal communication with friends of friends who own DADs tell me that their DADs alert to not only hypoglycemic events, but to asthma attacks, anxiety attacks, etc. If you read carefully, few studies ask owners of DADs if their dog gives a lot of false alarm signals (dog signals to their owner and after the owner checks their blood sugar, they discover that they are not low). 

Isn’t this fascinating? 

The dogs I work with are incredible (shout out to the amazing owners that let me work with their dogs every week), and have incredible work ethic and sniffers. 


Our dogs are extremely motivated to work (because we make it super fun!). This is Nutella on her “break”. She doesn’t want a break. She wants to keep working! She’s whining and pawing at the door of the work room.


With the assistance of these amazing dogs, hopefully Dr. Gadbois and myself will be able to shed light on how exactly DADs do their job in the near future - I'll let you know how we go!
