Which enables the dog to sense hunger, thirst, or a need to eliminate waste?

• A. Pain
• B. Internal Receptors
• C. Titration
• D. Aggression

Answer: (B)

Internal receptors detect the body's internal state and drive basic needs like hunger, thirst, and the urge to eliminate waste. These interoceptors monitor things such as stomach fullness, fluid balance, and bladder fullness. When the stomach signals hunger through emptying cues and gut hormones, the brain receives those signals and motivates eating. When hydration drops, brain osmoreceptors sense increased osmolarity and trigger thirst. Bladder stretch receptors relay fullness to the brain, creating the urge to urinate. This internal sensing guides the dog to act—eat, drink, or seek a restroom—without needing external prompts. Pain is a warning of potential injury, not specifically about hunger or thirst; titration is a method for adjusting intensity or dosage, not sensing internal states; aggression is a behavior, not the mechanism for detecting these needs.
