When dogs die the science of sad

,
Farewell to Elke
Ah, Julie...
I’m not even really sure where to start. 

"On Sunday I sat outside in the sun, stroking Elkes so-soft ears, while my husband patted her long, sleek back, and we farewelled our first girl. We learned on Friday that her liver and spleen were full of cancer. We are so grateful to have shared 12.5yrs with her and will miss her dearly." is what my Facebook status update said.
But lets start at the beginning...


Little Elke-Moo and her
cow hips, at RSPCA
I met Elke (pronounced Ell-kee) when I was in my third week of employment in the RSPCA shelter. What a sucker I was! She was seized as part of a cruelty case from a property where an elderly man with dementia had over forty dogs. Because of the dementia, the dogs weren’t receiving proper care and he sometimes fed them chicken pellets. Of her litter, Elke was the only survivor. She looked like a 5 week old puppy but she was actually 12 weeks old. 

She was always small. Our ‘bonsai pointer’, we called her. We joked that she was little, but could lay a good egg.  My boyfriend at the time and I had been speaking about getting a dog, and pointers had come up as a breed we were interested in – he wanted a dog to run with him. After three weeks of rehabilitation at RSPCA, she came home with me. I was 23 years old. Since then, she has been a fixture in the landscape of our lives - through house moves, our engagement and marriage, the death of my father, the arrival of our daughter, the comings and goings of oh-so-many other dogs (occupational hazard!).

Elke and my daughter - a fantastic introduction to dogs

Elke was energetic, excitable and hilarious. She wasnt perfect, but neither were we. We were a perfect match. She realised, as a young dog, that she could redirect attention to herself if visitors were over, by trawling our dirty clothes basket for recent underwear and then parading it through the lounge room for everyone to see. 


Post-beach snooze with our other dog, Caleb

She didn’t like thunderstorms or fireworks. She loved running off lead at the park, the beach or through the bush and she adored retrieving. She would regularly throw herself into water without stopping to check for a way out. One time I had to walk along a river back for about 500m while she swam and we looked for a place where she could scramble up the riverbank to get out again!

We took Elke to obedience training and she taught us so much. Elke was also more than our pet. She helped as a friendly adult dog at puppy preschool classes, she posed as a jaunty model as Australia legislated for the end of tail docking, she tried to distract trainee guide dogs and she visited nursing homes as a certified visiting therapy dog. They were all things we did together, my spotty dog and I.

Elke loved playing swim-retrieve in the water
 She and our other dog Caleb were very close. They had a silly play ritual they indulged in every day. Twice a day. A close-quarters mouthing and growling game that ended in howling calamity. It was sometimes annoying (working from home, it wasn’t always compatible with work-related phone calls!), but always made me smile. But now our house is very quiet.

We all loved time at the beach

We didn’t know Elke was sick until a week before she was euthanased. We took her to the vet, her temperature was up, a blood sample was taken, antibiotics were commenced. We didn’t know just how sick she was until two days before. What we did know, was that she was getting older, slowing down, not hearing the thunderstorms any more – and we knew she wouldn’t live forever. But that day always seems - in the future.

Instant couch-rights
When the vet rang me on Friday (the 13th) to advise that the ultrasound showed Elke’s liver and spleen were full of cancer, I was interstate at a conference aiming to eliminate the euthanasia of healthy and treatable pets in Australia. I was told that there were no options. Elke was comfortable, but at risk of bleeding internally and needed to be kept quiet with minimal activity. Euthanasia was not required immediately, but certainly the recommended course of action to avoid a slow and painful death by haemorrhage. I made the appointment for the day after I was due home and cried in my hotel room until there were no tissues left.

Sunday morning was a beautiful morning in Melbourne. The sun was out. I sat with Elke and my just-turned-3-year-old daughter in our garden. We talked about Elke being sick and that she was going to die. She asked hard questions. I did my best to answer them. We weren’t able to play retrieve, but passed Elke little sticks and she crunched them in her teeth. I took some last photos of the two of them – my girls – who have enjoyed a calm and positive relationship. Then Pete and I took Elke to the vet. She was given a mild sedative and we walked outside into the vet clinic’s garden (she never really liked veterinary consult’ rooms). We placed her bed on the grass in the sun, while she walked and sniffed. As the sedation took effect, I helped her settle onto her bed and she relaxed, dozing in the sun. Pete gently stroked her back. I had her relaxed head cushioned in my lap, savouring the sensation of her silky soft ears against my fingertips, one last time. She didn’t even notice the needle that entered the vein in her leg with the overdose of anaesthetic. It really was the perfect euthanasia.

Elke was doing selfies pre-Facebook - circa 2003

Now Elke is gone, and we’re adjusting to this changed landscape of our lives.

Despite all the dogs that have lived in our home, for days or for years, Elke is the first dog that we have owned from puppyhood through to old age. In some ways, this is helping me cope with her death.  With other dogs I think I’ve felt an element of anger that we had met too late for them to live their best life, or been robbed of time together through unexpected illness taking them too soon. But today, I’m trying to take comfort in the fact that Elke lived a fabulous and full life with us; her passing was as peaceful and stress free as any of us could hope for. I’m so grateful that our daughter had Elke to share her infancy with. 

It still hurts. In ways that bubble up unexpectedly. And I know that’s OK. Grief is messy. It’s individual and it takes as long as it takes. Time plays a critical role and will not be rushed.

Spooning in 2003.
Still besties in 2013.
Research over the past 25 years has shown us that grieving for a pet follows the same reactions and involves the same emotional responses as dealing with a human loss. People who have lost a pet commonly experience intense feelings such as sadness, anger, anxiety, disbelief, depression, panic, relief or even numbness. The act of consenting to euthanasia has been found to be particularly disturbing for some owners, who feel they have betrayed a trust by choosing death over life. Of course, grief responses to death of companion animals is linked to the strength of attachment we have with them, but we should not trivialise, nor brush aside our response to the death of our pets.

Animals are important to us and the grief we experience when they die is real.
We should be gentle to ourselves.

Acknowledging this and permitting ourselves to react (however we need to) is important. Letting our support networks (friends, family, colleagues) know how we feel and letting them help us in return is also important. If time isn’t helping, or you lack a support network, seek further help, from your doctor or a professional counsellor. The Australian Centre for Grief and Bereavement has helpful information about grief here. The number of friends who have sent me kind messages, called to see how were doing this week or even driven over just to give me a hug has shown me that a) Elke was a dog whose reach was long, and that b) I have amazing friends and family!

And so, my friend, I’m off to give Caleb a big hug. Because amongst all the other sad (for Elke, for my daughter, for me) I’m sad that he may never get to do this again:

Do As I Do Copy Cat Social Imitation in Dog Training

,
Join us for another guest post, this time from Claudia Fugazza of the Family Dog Project in Budapest. Claudias here to discuss her recent publication in Applied Animal Behaviour Science on the efficiency of new methods in dog training.

Hi Mia and Julie,

Formal training methods used until now rely mainly on the well-known rules of individual associative learning. These methods work perfectly well for a very wide range of animals — pigeons, rats, dogs and even crabs — and human and non-human animals can learn by ‘click and treat,’ as noted in the popular training book by Karen Pryor.




However, recent research has found substantial evidence that dogs could be predisposed to acquire information socially via the ‘Do as I do’ method. Do as I Do is a relatively new training method for people to use, based on dogs’ social cognitive skills, particularly on their imitative ability. 



With this training technique, dogs learn new behaviors by observing and copying their handler. The dog is a copycat. This method relies on social learning, and it was recently introduced in the applied field of dog training. 




As this method has started spreading in the dog training world, we felt that its efficiency and efficacy needed scientific testing. We were also wanting to know whether this method would be more or less efficient than other current training methods in training for particular behaviors.

We expected that dogs would more easily copy object-related actions from a human demonstrator so we tested dogs’ efficiency in this kind of tasks. To do this, I travelled across Italy and the UK with my video-cameras as well as a heavy Ikea cabinet filled with objects (you can imagine the weird looks I got from security personal at checkpoints!). I used these objects to test dogs learning to open or close drawers and lockers, pick up items from it etc. Since training methods can be affected by the skills of the trainer, only experienced dog-owners pairs who achieved a certificate either for the ‘Do as I do’ method or for shaping / clicker training were included in the study. Each pair was tested using ‘his’ method for teaching three different object-related actions in three testing sessions.


We expected that the ‘Do as I do’ method would prove more efficient for teaching complex tasks, compared to the shaping method that relies on individual learning. This expectation comes from what we know in humans: we tend to rely more on social learning when required to learn something difficult.

Our research found that the ‘Do as I do’ method proved more efficient for teaching dogs complex tasks, like close a drawer, open a locker and pick up an item that was inside (i.e., the time needed by the owner to obtain the first correct performance of the predetermined action was shorter with the ‘Do as I do’ method compared to shaping). We did not find a significant difference in the efficiency of the methods for teaching dogs simple tasks like knocking over a bottle or ringing a bell.

Now that we know a bit more on how to efficiently teach complex object-related actions, we are curious to know what happens when we want to teach different kind of complex actions, like body movements. We also want to know whether introducing social learning in dog training could have an effect on learning cues for trained action. 

We are aware that learning rates can be influenced by many factors, and we acknowledge that this study is just a very first step towards a more scientific approach to training paradigms. However we believe that this kind of information can be very important for the practitioners working in the applied field of dog training. We hope that the readers will not misinterpret the results and will not extend them to different actions and situations that were not tested.

Furthermore we would like to emphasize that, despite being efficient for training some kinds of actions, the ‘Do as I do’ method does not replace the methods based on individual learning (for example think of how many actions are not imitable at all if the demonstrator is a human and the learner is a dog!). Instead ‘Do as I do’ is a useful (and fun!) addition to existing training paradigms. Experienced dog trainers may find effective ways to mix the different training techniques in order to obtain the best results with each dog.
