The lungworm, Angiostrongylus vasorum, was first reported in indigenous dogs in southwestern England in 1980 and has since been recorded in Wales, southeastern England and, more recently, in the West Midlands, northern England and Scotland. The nationwide distribution of the parasite was evaluated using a postal questionnaire sent to 3950 small animal practices during 2009. Information was sought on the location of each practice, awareness of the parasite locally, number of cases diagnosed over the past year and whether diagnosis was based on clinical signs alone or supported by additional tests. 1419 practices returned a usable response, the majority being located in a city/town. Nearly one-third of responding practices were aware of the parasite locally, 20.7 per cent had seen at least one confirmed case and 0.3 per cent >20 confirmed cases over the past year. The most widely used tests were faecal examination and any type of imaging. Existing clusters of infection were detected in southeastern England and south Wales; infection was also found to be widespread in central England, though patchy in northern England and Scotland. Using distribution of clinical cases as an indicator of parasite distribution, this study confirmed that A. vasorum has spread beyond traditional UK endemic foci.

Accurate record keeping is important for many reasons, including demonstrating and recording activity and enabling safe transfer of care between professionals. An audit of child health records in Aberdeen and Aberdeenshire showed much good practice, but also areas for improvement.

Aims To evaluate the effects of racing and training conditions on motion symmetry we set out to quantify hindlimb symmetry using an objective inertial sensor‐based system in a cohort of in‐training Standardbred racehorses during high‐speed trotting and to assess the influence of speed, line taken (straight vs. bend) and direction of travel (clockwise vs. anticlockwise). Methods Eight Standardbred racehorses in full training were instrumented with a GPS‐enhanced inertial sensor located at the tuber sacrale and trotted around an oval racetrack at a range of speeds and in both directions. Symmetry index (SI), MinDiff, MaxDiff, vector sum (VS) and range of motion (ROM) were quantified for the hindlimbs for each stride using vertical displacement data derived from the inertial output. Results A total of 9108 strides were collected on the track. Overall, all horses displayed a right hindlimb asymmetry or ‘lameness’. Horses were more asymmetrical when trotting around bends compared with on straights. The main factor influencing asymmetry was trotting around a clockwise bend. Speed had a small but significant influence on asymmetry that varied between measures. Conclusions The inertial sensor system was suitable for collecting on‐track, high‐speed locomotion data. The magnitude of asymmetry was dependent on direction, possibly indicating subclinical lameness or laterality in these horses. Practical significance The inertial sensor system is practical for on‐track objective high‐speed lameness evaluation. Further studies with larger numbers of objectively sound and lame Standardbred horses are needed to determine the effect of lameness on high‐speed trotting. The influence of factors such as training regimes and racing equipment should also be evaluated. Ethical animal research All procedures were performed with approval of the Royal Veterinary College Ethics Committee. The study was carried out in accordance with local regulations and in collaboration with the Swiss National Stud and Vetsuisse Bern. Informed consent was obtained from the owners of all horses used.
