The welfare of dogs and cats during transport in Europe: a literature review

Commercial activities involving dogs and cats have become increasingly important and contribute significantly to the European economy. One of the most important activities is undoubtedly their translocation for commercial purposes. This is governed by the Council Regulation (EC) No. 1/2005 on the protection of animals during transport and related operations and amending Directives 64/432/EEC and 93/119/EC and Regulation (EC) No. 1255/97. Unfortunately, Regulation EC No. 1/2005 reports only a few specific mentions of companion animals. Since scientific studies on the effects of transport on the welfare of dogs and cats are scarce, much of the available information is in the form of recommendations based on practical experience, rather than evidence-based research. Up to date, the effects of food and water deprivation, the use of some drugs (e.g. sedatives and anxiolytics), or weather impacts on companion animal health and welfare during transport are still a matter of debate. Therefore, the aim of this narrative review is to summarise the European Regulation on dog and cat welfare during transport, suggesting possible implementation, and to document the negative effects of transportation, suggesting how to mitigate them based on scientific evidence. To date, habituation to containers and travelling, particularly using positive reinforcement training, seems to be the most effective strategy to reduce transport stress in these animals. However, still many gaps of knowledge are present and further studies are needed. This review may be useful for all people involved in the companion animal industry.
