Which of the following is an environmental cue that can trigger a dog's behavior?

• A. Grabbing the leash
• B. Opening food bin
• C. Starting to front door
• D. Turning affection away

Answer: (B)

Environmental cues are things in a dog's surroundings that have become reliable signals for a consequence through learning. When a food bin is opened, the dog perceives a clear, consistent stimulus that has historically been followed by food. That opening becomes a trigger the dog responds to with food-seeking behaviors, often even before the actual food appears. It’s a strong, automatic cue because it’s an external signal in the environment tied to a predictable outcome.

Grabbing the leash or starting at the front door are related to routines or human actions, but they aren’t as universally and reliably tied to a single, reward-based outcome in the environment. Turning affection away is social feedback and doesn’t serve as an environmental cue that predicts a tangible consequence in the dog’s surroundings.
