This article highlights a research project led by the LAGENBIO group at the Veterinary Faculty of the University of Zaragoza. The study aims to investigate the relationship between canine idiopathic epilepsy and potential molecular biomarkers in circulating exosomes to improve diagnosis and treatment. The initiative promotes citizen science by inviting dog owners to collaborate by providing information about their pets and allowing the collection of biological samples. This citizen-focused approach strengthens the connection between scientific research and society, contributing to the advancement of knowledge on diseases shared by humans and animals.
