宠物真正想要和需要什么 | Dr. Karolina Westlund
摘要
斯德哥尔摩大学动物行为学教授 Dr. Karolina Westlund 与 Andrew Huberman 共同探讨基于科学的家养动物需求——主要涉及猫和狗。对话涵盖动物如何通过进化形成行为、这些行为如何影响它们今天的需求、人类如何频繁误读动物信号，以及主人可以采取哪些措施来真正改善宠物的身心健康。许多关于动物行为的常见假设——从支配行为到猎物赠送——都通过动物行为学的视角被加以审视，并在很多情况下得到了纠正。
核心要点
- 狗的不同品种是通过选择性育种来表达狼捕食序列中特定部分——了解你的狗的品种倾向，可以告诉你它真正需要哪种类型的刺激。
- 大多数狗更喜欢缓慢、有节奏的抚摸，而非快速拍打；快速拍打可能令它们感到不适。
- 在抚摸前进行”同意测试”（伸出手，暂停，观察动物是否主动靠近）能够尊重动物的意愿并建立信任。
- 动物中的支配地位特指对资源的优先获取权——而非谁走在前面或谁先吃饭。大多数在狗的训练中使用的”支配”框架是对这一概念的错误应用。
- 猫是独居猎手；它们的食物应远离猫砂盆放置，如果你养了多只猫，应在不同地点分别喂食以减少冲突。
- 猫用头蹭你是气味标记行为——这是一种社交联结行为，而非将你视为”所有物”的表现。
- 狗摇尾巴的方向传递情绪信号：偏向狗的右侧摇摆与积极状态有关；偏向左侧摇摆与消极状态有关。
- 在2至8周龄期间每天至少接受1小时人类接触的幼猫，长大后会成为极具社交性的成年猫；每天少于约15分钟接触则会产生较为疏离但并不恐惧的成年猫。
- 马匹因过早断奶、单独饲养和受限的觅食时间而受苦——在野外它们每天觅食长达16小时，阻止这种行为的圈养方式可能导致问题行为的出现。
- 狗很可能是自我驯化的，通过主动选择在人类居住地附近生活——最不怕人、最具探索性的狼逐渐与人类建立了共生关系。
详细笔记
捕食序列与狗的品种
狼的捕食序列为：定向 → 目视/潜伏 → 追逐 → 抓咬 → 杀咬 → 分解 → 进食。在驯化过程中，该序列的特定片段在不同品种中被选择性地强化：
- 嗅觉猎犬：强化定向/嗅探阶段
- 指示犬：强化目视/潜伏；序列通常在追逐前停止
- 边境牧羊犬：目视、潜伏和部分追逐；抓咬被抑制
- 灵缇犬：纯粹的追逐者
- 寻回犬：强调抓咬
- 㹴犬：强调杀咬（专为消灭啮齿动物而培育）
- 牲畜护卫犬：主要保留嗅探行为；捕食序列基本缺失
- 玩具犬/伴侣犬：捕食行为极少
实际意义：提供符合你的狗品种特定倾向的丰容活动（例如，为嗅觉猎犬提供鼻嗅工作，为边境牧羊犬提供牧羊或追逐游戏，为㹴犬提供挖掘/狩猎游戏）。
核心情感空间：理解动物情绪
Dr. Westlund 使用核心情感模型来评估和改善动物福利。该模型绘制了：
- X轴：效价（愉快 → 不愉快）
- Y轴：唤醒度（低 → 高）
四个象限：
- 高唤醒 / 愉快 – 寻求、觅食、探索、玩耍、性行为
- 低唤醒 / 愉快 – 平静、安全、社交自在 （动物福利的目标状态）
- 低唤醒 / 不愉快 – 无聊、抑郁
- 高唤醒 / 不愉快 – 恐惧、攻击性
将动物引导至第2象限的方法：
- 减少恐惧和厌恶性体验
- 提供充满刺激、丰富的环境
- 给予适当的身体接触
如何抚摸你的狗（以及何时不该抚摸）
- 大多数狗不喜欢被拍打头顶；更喜欢被抓挠颈部、上胸部、臀部或它们自己无法自我梳理的部位
- 缓慢、有节奏的抚摸能令狗放松（眼睑下垂、肌肉张力降低）；快速拍打通常令狗感到不适
- 多迷走神经理论与共同调节：平静的人类能发送生理信号，真正帮助狗平静下来
- 使用同意测试：轻触后移开手——如果狗朝你靠近，继续；如果它移开，则停止
- 灵长类动物（人类）喜欢拥抱；但对许多动物来说，被抱住感觉像是被束缚，而非情感
支配：它的真正含义
- 动物行为学定义：在稳定的社会群体中对资源的优先获取权——降低代价高昂的攻击风险
- 社会学定义（常被错误地应用于宠物）：控制、权力、领导的等级制度
- 通常被标记为支配行为的动作（狗在绳索上走在前面、跳起来扑人、进入你的空间）更好地用学习和情绪状态来解释，而非支配
- 狗将人类视为与其他狗不同的存在；人类在犬类支配等级制度中不占有任何位置
- 支配等级制度在圈养条件下更为明显，因为动物无法分散以寻找替代资源
解读狗的沟通信号
- 摇尾方向：偏左 = 消极情绪状态；偏右 = 积极情绪状态
- 眼睛侧化：狗（和猫）倾向于用左眼观察引发恐惧的刺激，用右眼观察积极刺激
- 尾巴位置和速度同样传递情绪状态（低且快速 vs. 高且僵硬）
- 人类解读狗的肢体语言比面部表情更准确——部分原因是狗在情绪表达时使用与人类不同的面部肌肉
- 接触狗（即使是被动的文化接触）能提高人类解读狗的信号的能力
玩耍行为：MARS 框架
可以使用 MARS 框架将玩耍与攻击行为区分开来：
- M – 元信号（例如，玩耍鞠躬：前腿伸展，后部抬高）
- A – 活动转换（行为多变，不按真实打斗的固定顺序进行）
- R – 角色互换（体型较大/较强的动物允许较小的一方”获胜”）
- S – 自我设限（较强的动物故意限制自身以维持玩耍状态）
猫的行为与需求
- 猫进化为独居猎手，会松散地聚集成社会群体
- 最佳断奶年龄：社会化适当需持续至14周龄
- 猫保留了完整的捕食序列；将猎物带回家并非赠礼——而是将食物带到猫感到安全的地方
- 头部蹭摩/摩蹭：相互气味标记——群体内的社交联结行为
- 尿液位置标记：领地性排尿发生在窗户/门口；在猫砂盆附近但盆外排泄可能表明与疼痛的关联
- 猫砂盆放置：远离食物放置；猫天性避免在进食区附近排泄
- 早期社会化：在2至8周龄之间每天接受≥1小时接触的幼猫长大后会成为高度社交的成年猫；每天<15分钟则产生疏离但不恐惧的成年猫
拟人化与拒绝人格化
- 拟人化：将动物视为本质上与人类相同
- 拒绝人格化（Frans de Waal 提出的术语）：拒绝承认人类与其他动物之间的共同点
- Dr. Westlund 认为该领域已过度向拒绝人格化方向修正
- 情绪处理和情绪调节很可能跨物种共享，即使触发刺激不同
- 动物公平感的证据：卷尾猴在观察到其他同伴获得更好奖励时，会拒绝原本可接受的奖励（de Waal 等人）
- 动物共情的证据：在内聚性群体中，社会性动物有动力缓解群体成员的消极情绪状态
马匹福利问题
- 马是猎物动物和群居动物——天性警觉，具有宽广的视野
- 圈养马匹的主要福利问题：

What Pets Actually Want & Need | Dr. Karolina Westlund
Summary
Dr. Karolina Westlund, a professor of ethology at the University of Stockholm, joins Andrew Huberman to discuss the science-based needs of domesticated animals—primarily dogs and cats. The conversation covers how animals evolved behaviors that shape what they need today, how humans frequently misread animal signals, and what owners can do to genuinely improve their pets’ physical and emotional well-being. Many common assumptions about animal behavior—from dominance to gifting prey—are examined and often corrected through an ethological lens.
Key Takeaways
- Dog breeds were selectively bred to express specific parts of the wolf predatory sequence—understanding your dog’s breed predispositions tells you what kind of stimulation it genuinely needs.
- Slow, deliberate stroking is preferred by most dogs over fast patting; rapid patting can be aversive.
- Offering a “consent test” before petting (extend your hand, pause, see if the animal re-initiates contact) respects the animal’s preferences and builds trust.
- Dominance in animals is specifically about priority of access to resources—not about who walks in front or who eats first. Most “dominance” framing in dog training is a misapplication of the concept.
- Cats are solitary hunters; their food should be placed away from their litter box, and if you have multiple cats, feed them in separate locations to reduce conflict.
- A cat rubbing its head on you is scent marking—a social bonding behavior, not a sign of ownership over you.
- Tail direction in dogs signals emotional valence: wagging predominantly to the dog’s right is associated with positive states; wagging to the left is associated with negative states.
- Early handling of kittens (at least 1 hour/day between 2–8 weeks) produces highly social adult cats; less than ~15 minutes/day produces more aloof but not fearful adults.
- Horses suffer from early weaning, single housing, and restricted foraging time—in the wild they forage up to 16 hours a day, and housing that prevents this can lead to problem behaviors.
- Dogs likely domesticated themselves by self-selecting to live near human habitation—the least fearful and most exploratory wolves gradually formed a symbiotic relationship with humans.
Detailed Notes
The Predatory Sequence and Dog Breeds
The wolf predatory sequence runs: orient → eye/stalk → chase → grab bite → kill bite → dissect → eat. During domestication, specific segments of this sequence were selectively amplified in different breeds:
- Scent hounds: enhanced orient/sniffing phase
- Pointers: enhanced eyeing/stalking; sequence typically stops before chase
- Border collies: eyeing, stalking, and some chasing; grab bite suppressed
- Greyhounds: pure chasers
- Retrievers: grab bite emphasized
- Terriers: kill bite emphasized (bred to exterminate rodents)
- Livestock guardian dogs: primarily retain sniffing; predatory sequence largely absent
- Toy/lap breeds: minimal predatory behavior
Practical implication: Provide enrichment activities that match your dog’s breed-specific predispositions (e.g., nose work for scent hounds, herding or chasing games for border collies, digging/hunting games for terriers).
The Core Affect Space: Understanding Animal Emotions
Dr. Westlund uses the core affect model to assess and improve animal welfare. It plots:
- X-axis: Valence (pleasant → unpleasant)
- Y-axis: Arousal (low → high)
Four quadrants:
- High arousal / pleasant – seeking, foraging, exploration, play, sex
- Low arousal / pleasant – calm, safe, socially at ease (target state for welfare)
- Low arousal / unpleasant – boredom, depression
- High arousal / unpleasant – fear, aggression
To move animals toward Quadrant 2:
- Reduce fear and aversive experiences
- Provide stimulating, enriching environments
- Offer appropriate tactile contact
How to Pet Your Dog (and When Not To)
- Most dogs dislike being patted on top of the head; prefer scratching on the neck, upper chest, rump, or areas they cannot self-groom
- Slow, deliberate strokes cause relaxation (eyelids droop, tension decreases); fast patting is often aversive
- Polyvagal theory and co-regulation: a calm human sends physiological cues that can genuinely calm a dog
- Use a consent test: touch briefly, then remove your hand—if the dog moves toward you, continue; if it moves away, stop
- Primates (humans) are huggers; to many animals, being embraced feels like restraint, not affection
Dominance: What It Actually Means
- Ethological definition: priority of access to a resource within a stable social group—reduces risk of costly aggression
- Sociological definition (commonly misapplied to pets): hierarchy of control, power, leadership
- Behaviors often labeled as dominance (dog walking ahead on leash, jumping up, moving into your space) are better explained through learning and emotional states, not dominance
- Dogs understand humans as distinct from other dogs; humans do not hold a position in canine dominance hierarchies
- Dominance hierarchies are more pronounced in captivity because animals cannot disperse to find alternative resources
Reading Dog Communication Signals
- Tail wag direction: left-biased = negative emotional state; right-biased = positive emotional state
- Eye lateralization: dogs (and cats) tend to view fear-inducing stimuli with the left eye and positive stimuli with the right eye
- Tail position and speed also communicate emotional state (low and fast vs. high and stiff)
- Humans read body language more accurately than facial expressions in dogs—partly because dogs use different facial muscles than humans for emotional expression
- Exposure to dogs (even passive cultural exposure) improves human ability to read dog signals
Play Behavior: The MARS Framework
Play can be distinguished from aggression using the MARS framework:
- M – Meta signals (e.g., the play bow: front legs extended, rear elevated)
- A – Activity shifts (varied behaviors not in the fixed order of real fighting)
- R – Role reversals (larger/stronger animal allows the smaller one to “win”)
- S – Self-handicapping (stronger animal deliberately limits itself to maintain play)
Cat Behavior and Needs
- Cats evolved as solitary hunters that aggregate loosely in social groups
- Optimal weaning age: up to 14 weeks for proper socialization
- Cats retain the full predatory sequence; bringing prey home is not a gift—it is bringing food to a place where the cat feels safe
- Head bunting/rubbing: mutual scent marking—a social bonding behavior within the group
- Urine location mapping: territorial urination occurs at windows/doors; elimination outside the litter box near the box may signal pain association
- Litter box placement: keep it far from food; cats naturally avoid eliminating near feeding areas
- Early socialization: kittens handled ≥1 hour/day between 2–8 weeks become highly social adults; <15 min/day produces aloof but not fearful adults
Anthropomorphism vs. Anthropodenial
- Anthropomorphism: treating animals as essentially human
- Anthropodenial (term from Frans de Waal): refusing to acknowledge commonalities between humans and other animals
- Dr. Westlund argues the field has overcorrected toward anthropodenial
- Emotional processing and mood regulation are likely shared across species, even when the triggering stimuli differ
- Evidence for animal fairness: capuchin monkeys reject previously acceptable rewards when they observe others receiving better ones (de Waal et al.)
- Evidence for animal empathy: social animals in cohesive groups are motivated to buffer negative emotional states in group members
Horse Welfare Concerns
- Horses are prey animals and herd animals—vigilant by default with wide visual fields
- Key welfare problems in captive horses:
