5. The results of this survey facilitated the selection of a sample for the full survey; 178 practices ticked a box on the VOS indicating their willingness to be involved in an RSPCA Australia Pet Obesity Questionnaire, and they were sent the pet obesity questionnaire. In addition, RSPCA societies in each of the Australian States and Territories were asked to nominate up to four practices to take part in the survey. In total, the questionnaire was sent to 209 practices, 11·6 per cent of the estimated 1800 small animal practices in Australia (Australian Small Animal Veterinary Association, personal communication)
