A study has gained new insight into the minds of dogs, discovering that those that are anxious when left alone also tend to show 'pessimistic' like behaviour.
The research by academics at the University of Bristol, and funded by the RSPCA is published in Current Biology tomorrow (12 October). The study provides an important insight into dogs' emotions, and enhances our understanding of why behavioural responses to separation occur.
Professor Mike Mendl, Head of the Animal Welfare and Behaviour research group at Bristol University's School of Clinical Veterinary Science, who led the research, said: "We all have a tendency to think that our pets and other animals experience emotions similar to our own, but we have no way of knowing directly because emotions are essentially private. However, we can use findings from human psychology research to develop new ways of measuring animal emotion.
"We know that people's emotional states affect their judgements and that happy people are more likely to judge an ambiguous situation positively. What our study has shown is that this applies similarly to dogs – that a 'glass-half-full' dog is less likely to be anxious when left alone than one with a more 'pessimistic' nature."
In order to study 'pessimistic' or 'optimistic' decisions, dogs at two UK animal re-homing centres were trained that when a bowl was placed at one location in a room (the 'positive' position) it would contain food, but when placed at another location (the 'negative' position) it would be empty. The bowl was then placed at ambiguous locations between the positive and negative positions.
Professor Mendl explained: "Dogs that ran fast to these ambiguous locations, as if expecting the positive food reward, were classed as making relatively 'optimistic' decisions. Interestingly, these dogs tended to be the ones who also showed least anxiety-like behaviour when left alone for a short time.
"Around half of dogs in the UK may at some point perform separation-related behaviours - toileting, barking and destroying objects around the home - when they're apart from their owners. Our study suggests that dogs showing these types of behaviour also appear to make more pessimistic judgements generally."
Dr Samantha Gaines, Deputy Head of the Companion Animals Department from RSPCA, said: "Many dogs are relinquished each year because they show separation-related behaviour. Some owners think that dogs showing anxious behaviour in response to separation are fine, and do not seek treatment for their pets. This research suggests that at least some of these dogs may have underlying negative emotional states, and owners are encouraged to seek treatment to enhance the welfare of their dogs and minimise the need to relinquish their pet. Some dogs may also be more prone to develop these behaviours, and should be re-homed with appropriate owners."

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
