The way dogs respond to other dogs' barks, played forwards or backwards, tells us about the importance of timing in canine communication. Photo: Ammit Jack / Shutterstock By Zazie Todd, PhD I recently looked at the amazing story of how two dogs had been taught to go into an fMRI scanner – the beginnings of  canine neuroscience . Today’s blog is about a study that takes a different, less hi-tech, approach to understanding the canine brain. Siniscalchi et al were interested in how  dogs  process other dogs’ vocalizations, and whether they show lateralization of the hemispheres – in other words, whether the left half and right half of the dog’s brain have different functions. To begin with they needed to record some canine vocalizations. They took four dogs (two mixed-breed, one Border Collie, and one Rhodesian Ridgeback) and recorded the sounds they made during a disturbance, isolation, and play. To get the disturbance recording, they had the dog in a car with its owner, and

Simple steps to help your overweight or obese cat lose weight.

If you have any concerns about your cat's weight or diet, or simply want to know if your cat is a healthy weight, speak to your veterinarian. Many cats are overweight or obese. A review by Kathryn Michel and Margie Scherk, published in the Journal of  Feline Medicine and Surgery , summarizes the problem and the steps that should be taken to help cats lose weight. Their paper begins by discussing the serious health concerns caused by overweight and obesity: an obese cat is almost four times as likely to get diabetes as a normal-weight cat, and more likely to suffer from other problems such as urinary tract disease and lameness. They point out that just ten extra pieces of kibble a day, over and above what the cat needs, will cause a 12% increase i

Do expressions of happiness and disgust on a person's face tell dogs which box contains tasty food? Labrador Retrievers were one of the breeds to take part in the study Photo: Carolyn Brule / Shutterstock By Zazie Todd, PhD Dogs are very aware of human emotional states. An earlier blog post looked at  how dogs respond to a crying stranger . This week’s post is about whether or not dogs can use human emotional cues to tell them which of two boxes contains a tasty treat. The research was conducted by David Buttelmann and Michael Tomasello in Germany. They compared two sets of human emotional expressions: Happy vs Neutral; and Happy vs Disgust. They tested 58 domestic dogs (Siberian Huskies, Labrador Retrievers, Golden Retrievers, Border Collies and German Shepherds). The Siberian Huskies were tested at the open air enclosure where they lived, and the other dogs were all tested in a room, mostly with the owner present. The experimental set-up involved two cardboard

People who train their dogs with a shock collar report less success than people who use positive reinforcement, this study shows. Photo: Ksenia Raykova By Zazie Todd, PhD A new paper investigates how many people use electronic collars on their   dogs , and whether or not they think they work. This page contains affiliate links which means I may earn a commission on qualifying purchases at no cost to you. Electronic collars deliver a small electric shock as an aversive stimulus, with or without a preceding warning signal. It is useful to know how many people use them, since a recent British report on shock collars found they have the potential to cause harm if mis-used, and recommended controls on their use and design. The study took place in the UK and dog owners were recruited via questionnaires distributed to people out walking their dogs, at agricultural shows, at vet surgeries and pet shops. The questionnaire was adapted from a previous study by Blackwell and colleagu

By Zazie Todd, PhD There are many studies on the effects of music, from what kind of music will make us spend more time and money in shops to the effects that learning to play an instrument has on our brains. Now, scientists at Colorado State University have turned their attention to what kind of music dogs might prefer to listen to in kennels. Photo: Nata Sdobnikova / Shutterstock The study, by Lori Kogan and colleagues, took place at a kennel that housed rescue dachshunds (generally long-term) and also boarded dogs while their owners were away. Being in kennels can be a stressful experience for dogs as they are kept in a small space with limited access to outdoors, and limited human and canine company. Kogan et al wanted to know if music would help to make the kennel environment less stressful. They compared three different kinds of music: classical music (4 tracks), heavy metal (3 tracks), and some music that was specially designed to be relaxing for dogs (1 track). A

By Zazie Todd, PhD Last week, I looked at a study which found that attitudes to cats predicted public preferences for Trap, Neuter and Release programmes, but knowledge about cats and experience with feral cats did not. But does knowledge and experience predict attitudes to rescue dogs? A recent study by Kate Mornement and colleagues in Australia answers this question. In Australia, 36% of households have at least one pet dog , but as in other countries, a lot of dogs are in rescue and in need of homes. Understanding perceptions of rescue dogs is important as it can help in finding strategies to increase adoptions. Photo: Ondrej83 / Shutterstock The internet survey had 1,622 participants and included sections on demographics, attitudes to getting a dog, and beliefs about animal shelters and how they operate. Details of the survey were distributed via social networking, and both dog-owners and non-dog owners were invited to take part. Since some large dog and rescue organiz

Trap neuter and return (TNR) is seen as the most humane option for feral cats, survey shows. By Zazie Todd, PhD What should be done about feral cats? A recent survey in Athens, Georgia, investigated people’s preferences for three different methods: catch and euthanize, trap neuter and release (TNR), and the establishment of a feral cat sanctuary. Opponents of catch and euthanize schemes argue that it is inhumane to kill cats, and simply creates a cat-free area into which new feral cats will move. Trap, neuter and release programmes involve catching the cats and neutering or spaying them before releasing them; the cats continue to live in the same place, but are unable to breed. The third option in the survey was to “capture and place feral cats in a sanctuary just for them”. Athens was an interesting place for the study, since the issue of feral cats had been in the local news for some time. A new law was passed just prior to the survey, which effectively meant that TNR was the

Do dogs look to their person when something stressful happens, like infants do their parents? This study says yes. By Zazie Todd, PhD This page contains affiliate links which means I may earn a commission on qualifying purchases at no cost to you. When human infants see something they are unsure of, they look to their caregiver to see what their reaction is. This is called social referencing. It has two components: first of all, a look from the object to the caregiver; and second, a reaction to the object (approach or avoidance) that is influenced by the caregiver’s response. This is well established in infants at twelve months of age. Do dogs do the same thing? Two recent papers by Merola and colleagues set out to investigate, using a method similar to infant studies. They needed a slightly-scary object; something that will make a dog feel cautious, but not so scary that it will turn and run away. They decided to use an electric fan with streamers attached.  In the first p

This survey found out how many homeless dogs and cats there are in the UK - and the outcomes for them. By Zazie Todd, PhD The problem of pet overpopulation and homelessness is well known. Getting accurate figures for the number of homeless pets is a more difficult undertaking, since many organizations are responsible for stray and homeless animals. The results of a survey in the UK were recently published, and provide useful information about the scale of the problem, the wait times for animals to be accepted into rescue, and the likely outcome of their stay. The survey was conducted by Jenny Stavisky and colleagues at the University of Nottingham. They sent a questionnaire to all the rescue organizations they could identify in the UK. They used a snowballing technique, asking each organization to suggest other groups that they should contact. They identified over 2300 contacts, and got an excellent response rate of close to 40%. In some cases, the head office of an organization

Common behaviour problems in rabbits, rodents and ferrets include aggression and house-soiling. Photo: Oksana Shufrych / Shutterstock By Zazie Todd, PhD Many people keep rabbits, rodents and ferrets as pets. A study published last year by Normando and Galli (Padua University) is the first to investigate the kind of behavioural problems they have and how it affects owners’ feelings of satisfaction with their animals. Participants were recruited via an Italian rabbit forum, the University of Padua, and local veterinary clinics. The survey was completed by 193 people about a total of 371 pets. The pets included 184 rabbits, 59 mustelids (mainly ferrets, but also including two skunks), and 128 rodents (including guinea pigs, hamsters, gerbils, chinchillas, rats and other rodents). Most owners reported no problems, but 29% of rabbit owners, 53% of mustelid owners, and 20% of rodents had a behavioural problem. For rabbits, the most common problems were inappropriate toileting,

A report from the Companion Animal Welfare Council looks at the evidence so far on electronic collars in dog training. By Zazie Todd, PhD This page contains affiliate links which means I may earn a commission on qualifying purchases at no cost to you. In September, the UK’s Companion Animal Welfare Council published a report on the scientific evidence on the use of shock collars in dog training . They use the term ‘electronic pulse training aids’ or EPTAs, because the collars do not necessarily induce a ‘shock’ but may sometimes be used only to induce a tickling sensation. I will use the everyday term here. The report included the use of collars as a training aid as well as invisible fences designed to administer an electric current if the dog crosses a boundary. The independent review was chaired by Professor D.S. Mills, and looked at the scientific evidence, accepted submissions from interested parties, and undertook a small-scale survey of their use in the UK. The ten peer-re

The ground-breaking study in which two dogs were trained to keep still and have an fMRI. By Zazie Todd, PhD The main problem with the neuroscience of dogs is that they would have to be sedated to be in the scanner, and then their brain wouldn’t be doing its normal stuff. Until now. A team of scientists led by Gregory Berns at Emory University has successfully trained two dogs to go into the fMRI scanner and keep still long enough for a brain scan. Prof Berns says he got the idea from realizing what military dogs are trained to do – if a dog can parachute out of a plane with its handler, he thought, then surely it could do an fMRI. The dogs are Callie, a two-year-old feist (small hunting dog), and McKenzie, a three-year-old border collie. And while McKenzie does agility, Callie had only had basic obedience training, and is a rescue dog. (If anyone ever tries to say negative things about rescue dogs, tell them about Callie!). The dog training was complex and took place

When you're getting a puppy, it's best to see both parents if possible, according to a new study. Photo: Stephen Coburn/Shutterstock By Zazie Todd, PhD When people get a puppy , a standard piece of advice from many dog welfare organizations is that you should always ask to see the mother. This week, I’m reporting on a new piece of research that investigates whether or not this is good advice. The study, by Carri Westgarth of the University of Liverpool, UK, was designed to find out if there is a link between behavioural problems, the age of acquisition of a puppy, and whether or not the owner had viewed the mother and father of the puppy before they brought it home. It has long been suggested that improper welfare of the mother causes behavioural problems in puppies, and that seeing the mother is one way to ensure that the puppy is being raised in an appropriate environment. (See here for research on the long-lasting effects of puppy mills on breeding dogs ). The
