Influence of Omega-3 fatty acids on the learning ability of the Guide Dog during the training

Some studies show the usefulness of supplementation with long chain poliunsatured fatty acids (LCPUFA) in puppies during training through the evaluation of the ability of learning and memory. The purpose of this preliminary study was to evaluate the effect of DHA supplementation on learning abilities in a group of future Guide Dogs for the Blind during the phases of education and training. Two groups of six Labrador dogs (A, study group and B, control group), belonging to School of Guide Dogs of Tuscany (Italy), random selected, were included in the study. To evaluate the effect of supplementation, we used the standardized tests of the School as they are internationally recognized and can establish both character and learning skills of puppies. Some differences were observed between the two groups in some tests results; in particular in those that require a greater visual and sensory capacity and motor coordination as the grid (or abnormal surface) test and the tilting table test. The results obtained in this study could confirm the usefulness of a 35 mg/kg DHA supplementation during the first year of life for improving cognitive skills in dogs.
