dc.description.abstract | : For many years, dogs have been trained to detect objects through smell and help humans to locate dif ferent items. These dogs are specially trained to maximize their search capabilities, that this increased concentration
could lead to high levels of stress in the animal. The main aim of this study was to assess the stress levels at rest of
working police dogs, measured with infrared thermography and by the heart rate (HR).
To achieve this, we evaluated 18 working dogs (13 males and 5 females), half of which had been trained for drug
detection and the other half for explosives detection. Eye temperature (ET) assessed with infrared thermography was
collected in the kennels (ETK) and inside the police car (ETC), to test differences due to place of location. The mean
value between ETK and ETC (MET) and the difference between them (ETD) were also assessed. HR was evaluated
inside the police car. The influence of different factors (sex, breed, training type and age) on the stress perceived by
these animals was also measured. The results indicated that these animals showed higher ETK (36.8±1.1°C) than
ETC (36.1±1.0°C), with a similar coefficient of variation (3.0% and 2.8%, respectively). This could be due to the fact
that working dogs tend to be calmer when they expect to carry out the assigned job. On the other hand, no statisti cally significant correlations were found between ET variables and HR, thus supporting previous studies indicating
that these parameters differ in their physiological background. The GLM statistical analysis found that females (for
sex factor) and dogs trained for explosives detection (for training type factor) showed higher ETK and ETD than
males or dogs trained for drug detection. As for breed group, statistical differences between means were found only
for ETD, with Shepherd dogs showing higher increases than Retrievers. Thus, the results obtained in this study are
the first to show that ET measured using infrared thermography is a suitable tool to assess stress in working dogs; and
secondly, that the stress shown by working dogs in the kennel and the magnitude of the stress difference recorded
between kennel and police car is influenced by the environment. | es |
