What does it really mean when your dogs wags its tail?
Why do they sometimes like to eat poo?
And can cats really make good therapy animals like dogs?
Well animal behaviourist and certified dog trainer Dr Zazie Todd answered some curly questions around our canine and cat behaviours.
Todd told
Sunday Morning
there were many myths surrounding our furry friends, including what it meant when dogs wagged their tails.
She said the way a dog wagged its tail suggested it was
feeling positive
or negative emotions.
"There's some research that shows that depending on the side of the dogs body that they are wagging too, it tells you something about the hemisphere of their brain that's involved.
"So if the dog is wagging the tail to the left it would mean that the right hemisphere is involved and that's more associated with negative emotions, where as if their tail is wagging more to the right, that means that the left hemisphere is involved and that's positive emotions."
But she said not all tail wags from our fur friends were actually friendly.
"If the tail is quite up right and if it's kind of a tight wag and sometimes quite a quick one, that actually is a sign of the dog feeling stressed and aroused and that is also a sign that you should be more careful of that dog."

Todd said when it comes to the personality of a dog it is largely not determined by its breed.
"There's actually a lot of variability in a breed, in terms of how those dogs behave.
"There is probably more variability within breeds than, you know, between different breeds, so the breed of a dog doesn't tell you everything about how that dog is going to behave.
Genetics and environment both shaped a dogs behaviour, she said.
Todd said dogs eating poo is actually a really common behaviour.
"From the dogs perspective, poo seems to be quite a delicacy and something they enjoy eating and it might even have some nutrients in it from the food that has been eaten before."
She said the best thing owner could do was just not give their dog the opportunity to do so.
"Clearing up in our yards... maybe also have a conversation with your vet if your dog likes to eat poop often and think about making sure you have de-wormed them.
"As well we can teach them to leave it and that's a really helpful thing to teach dogs anyway," she said.
Cats can sometimes be a therapy animal.

Another mystery question that needed answering was whether cats could be a therapy animal like dogs?
Todd told
Sunday Morning
they could, but it was uncommon.
"Therapy cats can help people feel less stressed... but most cats won't enjoy this," she said.
"The cat also has to go somewhere for this to happen, which is something most cats don't like. If you think of what most cats do when you get a cat carrier out - they run and hide."
She also said scent was really important to cats, and when placed in an unfamiliar environment that didn't smell like their home "it can be quite stressful for them".
"So i think some cats can make great therapy cats but I think they are a minority."
Just like a dog wagging its tail, a cat purring didn't always mean they were happy, Todd said.
She said sometimes cats could purr when they were sick or scared.
"There is something that we call a solicitation purr... which kind of corresponds to the frequency of a babies cry.
"So when the cat is waiting to be feed and wants some food that is the purr you will hear," she said.
Cats have evolved this particular frequency overtime, Todd said.

Breaking the cycle of transgenerational trauma

Dr Tara-Lyn Camilleri Photo: SUPPLIED We inherit our genes but can we inherit trauma? There's no doubt we can feel it but can the trauma of previous generations be expressed in our genetic code? How does a parent's experience of war, ethnic persecution, cultural oppression, state or domestic abuse manifest itself in their child? Dr Tara-Lyn Camilleri from Monash University in Melbourne is an expert in transgenerational effects, looking at how the lived experiences of one generation can shape those that follow. An Oxford scholar, Dr Camilleri talks to Mihi about the relationship between biology, psychology and our environment and what we can do to break the cycle of transgenerational trauma.

The science of transgenerational trauma, epigenetics and hope for healing

Dr Tara-Lyn Camilleri studies epigenetics and the transgenerational effects of trauma. Photo: SUPPLIED Do we inherit the effects of trauma physically from past generations? Do parents' experiences of war, ethnic persecution, cultural oppression, state or domestic abuse have lasting effects, manifested in their children? There's no doubt we can feel it, but can the trauma of previous generations actually be coded into the bodies of their children? New research is beginning to shed light on this. Dr Tara-Lyn Camilleri, an Oxford scholar and now a researcher at Monash University in Melbourne, specialises in epigenetics - the interplay between our environments, lived experiences and how our genes are expressed. She talked to Mihingarangi Forbes about the biology and what that tells us about breaking cycles of transgenerational trauma. In a wider sense, "transgenerational trauma is when the effects of trauma in one generation ripple into the next generation, so it can shape us in a few key ways - biologically socially psychologically and culturally" Camilleri says. "So psychologically, if someone's experienced trauma it can effect how they parent, how they regulate emotion, and how safe their environment is in general - all will shape a child's development. Culturally trauma can disrupt people connection to culture, language, history, land, which can carry through generations if healing doesn't happen. So all of these things are constantly interacting with one another to produce these outcomes. "Biologically, stress can change how our bodies regulate things like hormones and immunity and those changes can be passed on sometimes through what we call epigenetic mechanisms - when we feel unsafe it can activate stress pathways in the body that alter how certain genes are expressed." Epigenetics is not changes to the DNA and genes itself, but changes to other biochemical tags that affect how DNA code is used, or to surrounding proteins. "I've described it as the directors notes on a script - these notes may tell the actors which lines to emphasise or downplay, but they're not changing the script itself," Camilleri says. For example, the fight or flight response is how the body continually responds to either real or perceived threats. And "this is when we start to get into the realm of phenotypic plasticity - it's a fundamental process in biology - it doesn't get a lot of attention, but things like stress or diet, these environmental conditions, can change our bodies, they change our neuroplasticity - the change the neurons in our brain, and they can change a whole host of other things, and that can induce these epigenetic changes." Genetics itself could mean a predisposition to experiencing stress in particular ways, including physically. Epigenetics can then "act like a volume dial" turning up or down those genes effects, and can be influenced by our parents experiences or our early childhood experiences. The effects of phenotypic plasticity can also be seen in the animal world, Camilleri says. For example what a honeybee is fed will determine if it becomes a worker or a queen. Some of those phenotypic changes can then be passed on to descendants, for example the body of stickleback fish can change to make it more difficult for predators to eat them. And this result can sometimes last for many generations when it is then cued by environmental factors like nutrients and hormones that regulate those responses. Camilleri says her own research with fruit flies found different nutrition and diet changes could result in different effects for different generations. One diet fed to both parents and their children resulted in the parents living longer but the offspring living shorter lives, whereas a different diet of more protein resulted in both grandmothers and granddaughters producing more offspring. The effects of transgenerational trauma can skip generations, and there are also actions we can take to mediate its effects, Camilleri says. "It's not always set in stone ... when we look at this research we don't see what we would call very predictable effects - it can change all the time. These epigenetic changes are what we call plastic, so they don't necessarily have to be permanent, and they are changing all the time throughout our lifetime all of the time. "So there are several things we can do to mediate it, to ensure that we might be able to break the cycle - but certainly even without intervention, our genetics are always talking to our environment. Our biology and our environment are always interacting with our social systems and our culture, so it's such a complicated mix of things that it's not always set in stone." Photo: (Pixabay Public Domain) Studies have found that how much of a parents' experiences result in factors affecting their children depends on which parent was affected, she says. Including one landmark study of cortisol (a stress hormone) in the children of holocaust survivors with PTSD. It found the children of mothers who were holocaust survivors were more likely to have cortisol dysregulation that made it more difficult to calm down from a stress response, compared to children of fathers who were holocaust survivors. "They are more predisposed to these baseline cortisol levels not being able to return to normal and keeping the body in ... a more prolonged stress state." Research has also found that breaking the cycle is more successful when the onus does not just fall on the individual, she says. "There are personal strategies. Obviously therapy, seeing a psychologist, building supportive relationships and learning to regulate our stress and emotion, it definitely helps and it's definitely very valuable - and that is where the emphasis is now, in society, it's sort of on the individual. "And I think what is changing is that we're realising that those personal strategies that we can do are most effective when other solutions address wider systems that people live in, so that means tackling the social, the economic and the environmental conditions that keep stress or inequity high... large-scale events, war, colonialisation. "Supporting things like cultural-led healing, community-led things by the people. Especially for these wide large-scale events - the people who've experienced these they need to lead these. Those voices need to be heard and listened to, so that it restores this sense of connection and identity and acknowledgement. Because it's about people feeling safe within the systems that they live in. "So when we change things at those broader levels we can reduce the load on individuals, and create those conditions where those individual strategies will be more likely to effect recovery and therefore affect subsequent generations."

Doctors call for NZ to ditch 'outdated' endometriosis guidelines

Endometriosis affects about one in 10 women and girls in New Zealand. Photo: 123rf New Zealand's "outdated" guidelines for treating the pelvic inflammatory disease endometriosis are delaying diagnosis and treatment for sufferers, warns an advocacy group. Endometriosis New Zealand spokesperson Dr Michael Wynn-Williams said new guidelines developed by the the Royal Australian and New Zealand College of Obstetricians and Gynaecologists were already being implemented in Australia for the painful condition, which affects about one in 10 women and girls. "This new guideline represents the gold standard in evidence-based care and is already being implemented across Australia," said Wynn-Williams, who chairs the clinical advisory committee. It recommends the use of non-invasive imaging, such as pelvic ultrasound, as a first-line diagnostic tool, moving away from reliance on diagnostic laparoscopy, which has contributed to long wait times for diagnosis. The current 2020 Ministry of Health document was no longer fit for purpose and needed to be urgently replaced with the new Australian Living Evidence Guideline, he said. "Our current guideline is now outdated, and out of step with modern diagnostic and treatment practices. "By contrast, RANZCOG's new guideline reflects the latest evidence and provides clear recommendations for early diagnosis, as well as first-line hormonal treatment to be run in parallel with diagnostic investigations. These are crucial to reducing the delays in diagnosis and treatment that too many patients still experience." Endometriosis New Zealand chief executive Tanya Cooke said adopting the new guideline would bring New Zealand into line with global best practice, and ensure patients received faster, less invasive and more equitable care. "We have written to the ministry and Te Whatu Ora, urging them to adopt the new guideline as soon as possible," she said. "It's also really important that they work with RANZCOG and others to support application of it across the sector, and for the benefit of the 120,000 New Zealanders living with endometriosis." A Health Ministry spokesperson said it was "grateful for the important work that RANZCOG has undertaken in developing these guidelines to support clinical care in this important aspect of women's health". "These guidelines represent a valuable resource, informing clinicians of evidence regarding diagnosis, management and care of people living with endometriosis. "Health New Zealand has established processes, through clinical networks and health pathways, to consider clinical guidelines and how they might influence on clinical service delivery to achieve better outcomes for New Zealanders." Health NZ national chief medical officer Professor Dame Helen Stokes-Lampard said clinical guidelines and health pathways were reviewed regularly. "Our immediate focus is on urgent patients and those who have been waiting the longest for treatment," she said. "We continue to work hard to put in place systems and processes, so improvements to waiting times are made."
