This episode is jointly released through the Functional Breeding Podcast and Cog Dog Radio, which is hosted by Sarah Stremming. Sarah is an internationally known dog behavior consultant with a special niche working with sports dogs. She consults at The Cognitive Canine, teaches online courses on dog behavior, and hosts the Cog Dog Radio Podcast. I sat down with Sarah to talk about fear periods - do they exist? What do we know about them scientifically? What do we know about them anecdotally? What do puppy raisers and breeders need to know about them?
