Obesity in horses and ponies, is according to many equine related charities (Blue Cross, BHS) becoming an increasing welfare problem. Recent studies have linked equine obesity and insulin resistance with development of debilitating laminitis (Vick et al., 2007). Poor nutritional management and sedentary lifestyles are to blame for the growing proportion of obese horses (Buff et al., 2005). The horse carer is responsible for the health and welfare of the horse and as such should monitor the weight, condition and exercise regime to ensure appropriate fitness levels to maintain health and performance. Indeed, Johnson (2002) reports that certain management practices tend to promote the development of obesity in mature horses as they enter their teenage years. Horse owners must therefore consider management practices throughout the horse’s life, as the provision of starch-rich and fat-supplemented rations to healthy horses that are relatively inactive may promote the development of obesity increasing the risk of laminitis (Johnson, 2002). The aims of this research were to ascertain the condition score and fitness levels of horses and ponies when diagnosed with laminitis, as reported by the horse carer and to gain insight into how these factors may influence the health and welfare of the domestic horse.
