Changes in the health and behaviour of pet dogs during the COVID-19 pandemic as reported by the owners()

The COVID-19 pandemic affects human health, movement and behaviour, and this may consequently influence the behaviour and health of their pets. The aim of this study was to assess the impact of the COVID-19 pandemic on pet dogs’ behaviour, as reported by their owners, as well as the owners’ experience in relation to their dogs. We hypothesized that dog owners who underwent lockdown or quarantine would indicate more behavioural changes in their dogs and experience support in having a dog during the pandemic. An international online survey asked dog owners questions regarding their household, the dog, and dog-related changes during the pandemic. A total of 688 surveys, collected May-June 2020, were analysed. Respondents were from across Europe (87 %), the Americas (9%), and Asia and Australia (together 4%). Data were analysed in GLMM models with a binary distribution and country included as random variable. The main predictor variable was whether the respondent experienced lockdown (300 respondents, 44 %), quarantine (76 respondents, 11 %) or no restrictions (312 respondents, 45 %). Respondents who underwent lockdown or quarantine were 1.8 times more likely to report behavioural changes in their dogs (p = 0.02), with more negative behavioural changes in the dogs reported by respondents in lockdown than expected by chance. However, overall behavioural changes were more often positive (30 %) than negative (24 %). Respondents in lockdown were 2.6 times more likely to report health changes in their dogs (p = 0.02). The dog was perceived as a source of support during the pandemic: 65 % of the respondents indicated reduced tension due to their dog and 47 % indicated that the ability to walk the dog outside was another benefit. Advantages were reported more by respondents in lockdown and quarantine as compared to respondents who did not face these restrictions (p < 0.001). Difficulties in dog care were increased for respondents who experienced lockdown or quarantine (p < 0.01) and those who had no garden as compared to those who did (p < 0.001). One-third of the respondents took dog-related measures to prevent the spread of the coronavirus, and this was associated with more behavioural changes and more difficulties. In conclusion, lockdown, and to a lesser extent quarantine, may influence the dogs’ behaviour and health, or the owners’ awareness of it, and can contribute to a perceived tension-reduction in the owners.
