The restrictive measures implemented to stem the spread of COVID-19 abruptly changed the lives of many cats and their owners. This study explored whether the lockdown in Italy affected the cat–owner relationship, as well as cat behaviour and welfare. A survey that included questions on owner and cat’s demographics, living environment, cat behaviour...

Previous studies on the dog intraspecific attachment carried out with the Strange Situation Procedure (SSP) have not been able to clarify the nature of this bond. Several factors may affect the behaviour of the dog dyads involved the procedure. In the current study, fifty-five dyads of adult dogs living in the same household participated in a SSP....

In canines, size at birth is determined by the dam’s weight, which would probably affect the newborn’s viability due to litter size and birth order. Fetal hypoxia causes distress and acidemia. Identifying physiological blood alterations in the puppy during the first minute of life through the blood gas exchange of the umbilical cord could determine...

Veterinarians’ perceptions of animal stress influence their practice. Therefore, the aim of this research was to evaluate how veterinary students perceive stress in dogs. Two hundred and eighteen 4th year veterinary students of the University of Cordoba (Spain) participated in the study. An online questionnaire measuring veterinary students’ percep...

Welfare assessment of dairy calves is commonly conducted through the observation of their behavior and the analysis of physiological parameters. Despite the large number of studies on this topic, there is a lack of research on the possible correlation between the physiological parameters and behavior at basal level in dairy calves. For this reason,...

To date, the Strange Situation Procedure is the only tool available to investigate the quality of the dog’s attachment bond towards the owner. This study aimed to adapt a parent-report scale, named the Attachment Insecurity Screening Inventory (AISI) 6–12, originally designed to assess 6- to 12-year-old children’s attachment insecurity, to dog–owne...

Genetic variations in the oxytocinergic system, known to regulate social behavior throughout the evolution of mammals, are believed to account for differences in mammalian social behavior. Particularly, polymorphic variants of the oxytocin receptor (OXTR) gene have been associated with behavioral variations in both humans and dogs. In this study, w...

In veterinary behavioral medicine and in veterinary neurology, there is an effort to collaborate with different consultants, as seen both in human psychiatry and in human neurology. This cooperation can lead to a complete assessment of any case, to a more holistic collection of information regarding the development of the case, and to a synergetic...

In recent years, many studies on the role of oxytocin (OXT) in the onset of parental care, regulation of social bonding, and modulation of the emotional state have been published. However, its possible regulation of maternal behavior in lactating dogs has not been investigated yet. For this reason, the present study aimed at assessing potential cor...

In social animals, recognizing conspecifics and distinguishing them from other animal species is certainly important. We hypothesize, as demonstrated in other species of ungulates, that horses are able to discriminate between the faces of conspecifics and the faces of other domestic species (cattle, sheep, donkeys and pigs). Our hypothesis was test...

In mammals, serotonin (5-HT) levels depend on the availability of tryptophan (TRP). Low 5-HT concentrations have been linked to behavioural disorders in dogs. This study aimed at investigating possible differences in dogs’ serum TRP and 5-HT concentrations according to their behavioural response to a potentially stressful procedure. Thirty-nine phy...

Since several modified Strange Situation Procedures (SSP) have been used to investigate dog-to-owner attachment, in this study two different samples of dog-owner dyads underwent two modified versions of the SSP. Dogs’ attachment style to the owner was assessed based on a novel adaptation of the attachment pattern classification used for infant-care...

Mammalian parental care, in most of the cases, is given by the female, who provides food, warmth, and protection. In domestic dogs, maternal behaviour shown by the dam mainly consists of contact, nursing, grooming/licking, play, punishment, thermoregulation, and motion. Peer-reviewed literature published between 1952 and 2018 was retrieved from CAB...

A shelter environment tends to present different types of stressors dogs need to cope with. Recent work has shown that olfactory enrichment with essential oils might be able to modify the affective states of certain species (dogs, cats, horses, zoo animals…). In these studies, the welfare measurements included physiological indicators, such as cort...

Poster
Prolactin has high circulating levels in lactating females and is a remarkable clinical index of stress response, both acute and chronic, in several species. The possibility to measure prolactin in dog saliva would provide a non-invasive, helpful tool for the assessment of dog welfare. The aims of this research were to investigate the possibility o...
