About Dr. Emily Bray 🧠
🎓 Assistant Professor, The University of Arizona 🐕 Director of the Behavioral Research Across Years (BRAY) Lab 🔬 PhD in Cognitive Psychology
Emily Bray brings a unique perspective to canine science, bridging evolutionary anthropology, behavioral cognition, and real-world applications. Her work at Canine Companions and the University of Arizona explores how genetics, environment, feeding practices, and mental engagement impact your dog's healthspan and cognitive longevity.
In This Episode 📺
We dive deep into the science of dog aging and cognition with one of the leading researchers in the field. Discover surprising findings about feeding frequency, learn how to spot cognitive decline in your senior dog, and explore the factors that genuinely affect your dog's brain health and longevity.
Don't miss the groundbreaking research on feeding frequency that contradicts everything you thought you knew!
