The anticipation and consumption of peanut butter trigger dopamine release in dogs' brains, creating a pleasurable sensation and reinforcing their love for the treat. Additionally, its use in play and as a treat makes it an exciting reward that dogs look forward to. Overall, the combination of enticing aroma, rich nutritional content, enjoyable texture, and positive emotional connection makes peanut butter highly favored by dogs.
