“…Reasoning Dauchy and Blask (2022) reported that setting parameters for artificial lighting is important for dogs but no studies were retrieved to suggest a specific setting. Schork et al (2022): relation between sleep and daylength (more than 12 h of natural daylight could affect sleeping behaviour).…”

“…time budget of active and inactive behaviour during light and dark phases) parameters have shown circadian rhythmicity (Zanghi et al., 2012 ; Giannetto et al., 2014 ; Cerutti et al., 2019 ; Cerutti et al., 2022 ), driven by an internal ‘clock’ located in the suprachiasmatic nucleus of the hypothalamus (Cerutti et al., 2022 ). This mechanism is an autonomous internal daily timekeeper that is influenced by environmental factors (Bertolucci et al., 2008 ; Cerutti et al., 2022 ; Schork et al., 2022 ). Among these environmental factors, light and light–dark cycles are the most important (Dauchy and Blask, 2022 ).…”

This Scientific Report addresses a mandate from the European Commission according to Article 31 of Regulation (EC) No 178/2002 on the welfare of cats and dogs in commercial breeding establishments kept for sport, hunting and companion purposes. The aim was to scrutinise recent recommendations made by the EU Platform on Animal Welfare Voluntary Initiative on measures to assist the preparation of policy options for the legal framework of commercial breeding of cats and dogs. Specifically, the main question addressed was if there is scientific evidence to support the measures for protection of cats and dogs in commercial breeding related to housing, health considerations and painful procedures. Three judgements were carried out based on scientific literature reviews and, where possible a review of national regulations. The first judgement addressed housing and included: type of accommodation, outdoor access, exercise, social behaviour, housing temperature and light requirements. The second judgement addressed health and included: age at first and last breeding, and breeding frequency. Judgement 3 addressed painful procedures (mutilations or convenience surgeries) and included: ear cropping, tail docking and vocal cord resections in dogs and declawing in cats. For each of these judgements, considerations were provided indicating where scientific literature is available to support recommendations on providing or avoiding specific housing, health or painful surgical interventions. Areas where evidence is lacking are indicated.

A Golden Retriever male was exhibiting owner-directed aggression (growling, snarling and baring teeth) and occasional avoidance behaviour of the male owner within the home environment. Blood tests and X-rays prior to assessment were unremarkable in addition to an unsuccessful analgesic trial. Extensive information gathering was undertaken during the assessment and in the months that followed. Potential motivating factors identified, including gastro-intestinal discomfort, frustration, physical stress (lack of appetite and lack of rest) and defensive behaviour, proved challenging to isolate. A multi-modal approach to behaviour modification was applied, including further exploration of the dog’s health to rule out undiagnosed pain. giardiasis antigen was identified during a faecal screen and treated, resulting in an improved appetite. Potential gait abnormalities were observed leading to examination by a hydro therapist and registered physiotherapist, both of whom could not identify any concern. Following the owner reporting a potential pain response to the dog’s hind-foot being touched, the referring veterinarian opted to prescribe a second analgesic trial using a different medication. Aggressive incidents ceased to occur while the dog was on pain relief, and the aggressive behaviour returned once the trial was completed. This led to the continued use of analgesia and a further cessation of aggressive behaviour, despite no formal health diagnosis being made by the referring veterinarian to date.
