Preventing dog bites when you dont have a hero cat

(source)

Hey Julie!

So much going on I need to take three deep breaths to calm down!

Firstly - we have a winner! Actually - thanks to the awesome crew at SPARCS, we have two! Very excited to meet Marsha P and Kristi M at #SPARCS2014 and want to thank all the excellent people who responded to our giveaway shoutout on Facebook, Twitter and Google+. We hope those of your who werent successful will consider still coming along or joining us on the livestream broadcast.

Secondly - I loved learning about the differences in UK and US shelter workers perceptions of pit bulls and all the associated bits and pieces that went along with that in our latest guest post by Dr Christy Hoffman. Really, really interesting research and I look forward to the next piece of the puzzle (aka new science) in that area.

Thirdly - its dog bite prevention week in the USA right now! We cant all own Tara the Hero Cat (and to be fair, as much as she is worthy of her notoriety and 20million+ hits on the viral video showcasing her ninja skills, she didnt actually prevent the bite - although Im pretty confident she helped prevent it being a whole lot worse). If you somehow missed what on earth Im talking about - check out this clip of amazing Tara (but a warning, it does show security camera footage of a child being attacked by a dog and the subsequent wounds):

Which brings us back to Dog Bite Prevention Week. We dont have a week like this in Australia, so I did some web trawling to check out what you guys have going on over there. 

The AVMA have put up a whole lot of great information and resources about dog bite prevention, including this neat summary infographic:

I was really pleased to see this analysis of information about the role of breed in dog bite risk and prevention, which reminded me of this piece on The Conversation by researcher Dr Rachel Casey from Bristol University in the UK, who has been part of a team investigating aggressive behaviour in dogs.

The broader research in this area (see below for references) highlights similarities across Australia, the UK and the US with most serious dog bites occurring to children by a known dog in a familiar area without direct adult supervision at the time of the attack. But of course - as Hero Cat Tara has shown us this week, not all dogs stick to these trends.

It seems that there are many commonalities to serious dog bites that we can all be aware of to help reduce the risk, given that any dog can bite:

• Supervise children <14yo around dogs, even known dogs
• Dont try to pat a dog you dont know, even if it is on the other side of a fence
• Make sure your dog is well socialised and trained in basic commands
• Keep your dog healthy
• Teach your children to be mindful and careful of their actions around dogs, especially when the dog is tied up, eating or sleeping
• If you are threatened by a dog, remain still and calm with your hands balled by your sides - dont run
• If you are attacked by a dog, curl up in a ball and protect your face

Im off to reinforce messages of safe dog interacting with my pre-school aged daughter now - hope you have a great week. 

Only one month til #SPARCS2014! Squee!

How do dogs and people respond to a crying baby

Guest post by: Min Hooi Yong, PhD

“Does your dog know when you are sad?” Puzzling question, perhaps? 

We get a range of answers from dog owners, from the confident “Yes!” to “Maaaaybe?”, and the hopeful “I like to think so...”. Many dogs are considered to be part of the family, and we expect our family members to empathize with us when we are sad.

A recent study found that dogs showed submissive behavior (licking and nuzzling) when an adult person pretended to cry but not when she is humming¹. Does the licking and nuzzling behavior mean that the dog understand that we are feeling sad? (I hear YES-es). Or can it be that because we are crying, we ignore everyone including our dog, and so, our dog will nuzzle us seeking attention and/or comfort?

There have been many studies showing that animals (e.g. rodents, birds, chimps) experience distress or concern (empathic response) when observing either kin or non-kin in distress. For example, giving electric shocks to rats and pigeons. The observer experienced a change both behaviourally and physiologically, and these responses are often considered as an experience of emotional contagion, an elementary form of empathy. Emotional contagion is essentially the spreading of all forms of emotion from one person (or animal) to another (like the spreading of joy or distress through a crowd - think of a flash mob dance effect filtering through a crowd)².

Hearing a baby cry can be quite distressing. What happens to us when we, the observers, hear the cry? We respond by getting up and checking on the crying baby, “increased attention”. Our body also releases the stress hormone cortisol when we hear the cry, regardless of age or parenting experience^3,4. Also, we can tell if the crying is urgent or not. We do, sometimes find crying aversive (imagine a baby crying non-stop throughout your long-distance flight).

In our study, we wanted to know if dogs and humans show a similar physiological response to a baby crying. We had three questions: 

1. We know that dogs are attached to humans, so would dogs show increased attention to a baby crying and babbling? 
2. Exposure to uncontrollable white noise is considered aversive and elicits submissive behavior. If dogs find crying aversive, would dogs show submissive behavior towards crying as well as white noise? 
3. Do dogs show an increased stress response (measured in their salivary cortisol levels) to a baby crying compared to white noise and a baby babbling, similar to humans?

We had 75 dogs and 74 humans listen to one of three sounds. A human baby crying:

A human baby babbling: 

Or white noise:

Each sound was played at an average volume of 82 decibels – similar to chamber music in a small auditorium (not loud enough to cause hearing damage, but it is loud). We collected saliva before and after listening to one sound from both dogs and humans for their cortisol levels. We also analyzed dogs’ behavior while the sound was played, and collected sound ratings about how aversive people found the sounds.

What did our three questions reveal? First, we found that both dogs and humans showed an increase in cortisol levels only after listening to crying, but no changes to baby babbling and white noise. Second, dogs showed increased attention to both the crying and babbling sounds, but not to white noise. Third, dogs displayed increased submissive behavior (e.g. the dog’s body and head were lowered, the ears were held flat and back, the tail was lowered and sometimes slightly between their legs or wagging rapidly side-to-side, the tongue pro-truded slightly, or the dog raised one leg in a hesitant or placating manner) to the crying and white noise, but not to babbling. Additionally, human participants rated the white noise as more aversive than crying (see table below for a summary). We also analyzed other possible aspects that might have influenced the dogs’ responses such as time of testing, demographic data e.g. neutered status and sex, acoustic features in the sounds (pitch and melody), and even dog owners’ unintentional cuing. We found that the responses shown were a result of distress, evident from crying.

You might ask why submissive behavior was shown during crying and white noise. Let’s start with white noise. Our human participants perceived white noise as more unpleasant compared to crying. Humans tend to cover their ears and animals also show similar avoidance, and what better way than to lower your head? On the other hand, with crying sounds, one is generally more subdued (sympathetic concern) especially when you can hear the distress meaning in the sound. The combined behavioral indicators during these sounds (e.g. lowered posture, shaking, stimulus avoidance) points toward submissive behavior.

In humans, an increase in cortisol and attention is interpreted as a demonstration of
emotional contagion^3,4. This unique pattern of physiological and behavioral responding to crying in our study is most consistent with (a) emotional contagion in dogs, providing first evidence that dogs, like humans, experience a physiological response to human infant crying, and (b) suggests the first clear evidence of cross-species empathy (i.e. canine emotional contagion to human distress).
