Frustration is a negative emotional state implicated in a range of canine behaviour problems. The Canine Frustration Questionnaire (CFQ) is the first psychometric tool developed to assess frustration tendencies in dogs based on owner report. However, to date, no published studies have assessed behavioural and physiological correlates of this trait. A novel behaviour test battery was developed to induce frustration in dogs, mapping onto the CFQ. Forty-four dogs were recruited and filmed whilst undertaking the test battery, and a CFQ was completed by each owner. Targeted behavioural measures were assessed from this footage, based on hypotheses aimed at evaluating convergent and discriminant validity with facets of the CFQ. In addition, a saliva sample was collected pre- and post-testing for 39 dogs, and a cortisol assay performed using ELISA to provide a physiological measure of arousal. A range of predicted behavioural test measures (e.g., vocalising and lunging) positively correlated with CFQ scores. For 22 dogs with pre-test salivary cortisol levels of <4 ng/mL (indicative of normal arousal at baseline), cortisol change and post-test cortisol levels positively correlated with the CFQ PC5 ‘Frustration coping’ score. These results provide further evidence of the validity of frustration tendencies as measured by owner report through the CFQ.

Canine cognitive dysfunction syndrome (CCDS) is a progressive age-related neurodegenerative disorder in dogs. Minimal research has been performed to investigate how clinical signs may be impacted by other medical conditions. A cross-sectional study was performed using the Canine Cognitive Assessment Scale (CCAS) to evaluate cognitive impairment as reported by owners. Owner-reported health-related measures included behaviour changes, the body condition score, and veterinary diagnoses of disease. The responses from 804 dogs in the last 25% of their expected lifespan were analysed. Factors were identified in the owner-reported behavioural signs of disease representing pathologies in four body systems: musculoskeletal–neurological, digestive, metabolic, and dermatological, with the items comprising these factors also compiled into a cumulative measure of health. The results showed a strong correlation between the CCAS score and both the musculoskeletal–neurological factor and the overall cumulative measure of health. Moderate correlations between the CCAS score and the digestive factor and metabolic factor were also observed. The correlation between the dermatological factor and the CCAS score was weak. This study highlights the need to screen dogs for concurrent diseases when using scales to assess cognitive impairment and to monitor dogs who have health conditions, particularly those that are painful, for the onset of cognitive impairment.

This is the first report of aggressive behaviour as the primary presenting sign in two dogs subsequently found to have chronic diskospondylitis, with neither dog showing other typical clinical signs of this condition. Mild signs of pain were elicited on physical examination in both dogs. Further medical investigation revealed signs indicative of chronic diskospondylitis (L7/S1) and treatment with analgesics and antibiotics was commenced. A marked improvement in behaviour was seen in both dogs when on treatment. Dog 1 stopped exhibiting unpredictable episodes of growling and biting when handled or approached and dog 2 stopped vocalising and occasional growling when handled or lifted. Gradual treatment withdrawal (dog 1 after six weeks and dog 2 after four weeks, respectively) caused a recurrence of behaviour signs thus further treatment was recommenced. Continued follow‐up over a year revealed the importance of long‐term use of analgesics to prevent behavioural deterioration when chronic lesions are present.

Problem behaviours in cats, such as urine marking, scratching, fear, and problems of cohabitation between cats, can present a potential welfare problem for those affected cats and have a negative impact on the human–animal bond. The aim of this study was to develop a Cat Behaviour Issues Assessment Scale (CABIAS) for caregivers to assess these common problem behaviours in cats, and to investigate aspects of the validity and reliability of the CABIAS. The CABIAS uses an index score as a scoring system combining aspects of the frequency and intensity of the problem behaviour. An electronic survey was developed, and 384 households, each with two participants able to observe the cat’s behaviour, were recruited for the study. The participants were asked to record their cat’s behaviour independently at weekly intervals over a 6-week period. A FELIWAY Optimum diffuser (containing a commercial feline pheromone complex) was provided to half of the participants, to be used during part of the study. The participants were subdivided into four groups according to whether a problem behaviour was present (or not) and whether the pheromone diffuser was provided (or not). The results demonstrated that the index scores for each problem behaviour had very high inter-rater reliability. There was a high correlation between the index scores and the impact the problem behaviours had on the caregivers. In those cats with a declared problem behaviour where the product was used, a reduction in index scores was observed over the duration of the study. The CABIAS was shown to exhibit satisfactory validity, reliability, and sensitivity to change in the current study, suggesting that it may be valuable as a tool for assessing and monitoring scratching, inter-cat cohabitation, urine marking, and fear in cats. The CABIAS could be used by veterinarians and behaviourists to assess these problem behaviours in individual cats and monitor responses to treatment. The CABIAS could also be considered as a research tool to assess the efficacy of interventions aimed at improving these problems.

This is the first documented case of scent triggering episodes of feline hyperaesthesia syndrome (FHS). A 1‐year and 5‐month‐old cat was referred to the feline clinic with a 5‐month history of generalised twitching of the dorsum, vocalising, compulsive grooming and darting/running episodes. A diagnosis of FHS was made following exclusion of other differential diagnoses. The cat had co‐morbid behaviour problems and was referred to the behaviour clinic. Triggers for FHS were explored: most episodes were unpredictable and without a consistent trigger; the cat was diagnosed with attention seeking and frustration‐related problems. A behaviour modification programme was developed, and a detailed diary was kept. Improvements were reported in general behaviour, as well as frequency and intensity of episodes of FHS. Episodes of FHS continued sporadically and were clearly linked to scent triggers (scented candles, cigarette smoke, cooking spices). Scent should be therefore be considered as a potential trigger for episodes of FHS.
