114. Physical response of dogs supplemented with fish oil during a treadmill training programme. (PubMed)

Physical response of dogs supplemented with fish oil during a treadmill training programme. The rise in popularity of dog sports competitions has led to the evaluation of improvements in dog physical performance. The potential benefit of dietary supplementation with fish oil (FO) on the physical performance of human beings and horses has been reported. However, such effect has not been studied in dogs. We therefore evaluated the effect of FO dietary supplementation on heart rate (HR), rectal (...) temperature (RT) and thigh circumference (TC) in dogs during aerobic treadmill training, and further determined HR response and blood lactate (BL) concentration during an incremental exercise test. Using a cross-over design, eight male dogs were randomly assigned to two groups and received a standard balanced commercial diet (control, CG, n = 7) and the same diet supplemented with 54 mg FO/kg metabolic weight per day (FOG, n = 8). All dogs had 30-min treadmill sessions at 8 km/hr and 7.5% slope twice
