Eldin Leighton has a PhD in animal breeding, and after a long career at The Seeing Eye, has founded the International Working Dog Registry, or IWDR. If you didn't listen to last week's episode where Eldin talked about his career before the IWDR, definitely check that out first. In this episode, he tells us all about the IWDR, how it helps gather large populations of dogs together to provide more data - and analyze that data! - to help breeders improve their breeding decisions, and whether it's useful for more than just working dogs. (Spoiler: yes it is.)
