Yorkshire Terriers — often called Yorkies — are one of the most beloved companion dog breeds in the world. From their tiny size to their big‑hearted personalities,’s there something special about how they attach to their humans. But what’s really behind that seemingly unbreakable bond?
In this deep‑dive article, we’ll explore:
🔹 The science of the dog‑human attachment
🔹 How Yorkies’ breed traits amplify bonding
🔹 Oxytocin and the “love hormone”
🔹 Emotional intelligence and social communication
🔹 Separation anxiety and attachment styles
🔹 Owner behavior and the environment’s impact
🔹 Real‑world examples from Yorkie owners
🔹 How to strengthen your bond with your Yorkie
By the end, you’ll understand why Yorkies feel so close to us — and how that bond affects both dog and human.
1. The Science Behind Dog‑Human Bonding
Dogs are among the few animals that form attachment relationships with humans that resemble human‑to‑human bonding. Scientists have uncovered some of the key elements that underpin this connection:
Oxytocin — The “Love Hormone”
Oxytocin plays a major role in forming emotional bonds. When dogs and humans interact — especially during eye contact, petting, play, or shared affection — both species experience a surge in oxytocin, often dubbed the “love hormone.” This chemical helps reinforce trust, affection, and social bonding.

This hormonal feedback loop is similar to what happens in human romantic and parental attachments, and it helps explain why dogs can become emotionally attached to us so intensely. workingwithpets.com
Attachment Behaviors and Emotional Response
Scientific research reveals that dogs show attachment patterns similar to human infants. In laboratory situations, dogs behave like securely attached infants — they explore more in the presence of their caregiver, become distressed when separated, and greet the caregiver joyously upon return. Paw’s Academy AU
These patterns aren’t just cute behaviors — they mirror core components of attachment theory, a psychological model that describes how bonds form and influence emotional development.
2. Yorkies: Breed Traits That Promote Strong Attachment
While all dogs are capable of bonding with humans, Yorkies have several characteristics that make attachment particularly intense:
Terrier Personality & Size
Yorkies descend from small terriers bred to work closely with people in tight quarters (like mills and homes). Over generations, this selection favored dogs that stayed alert, attentive, and responsive to their human partners, traits that now contribute to their bond. workingwithpets.com
Their small size — often 4–7 pounds — means they are constantly at human eye level and physically close, which reinforces bonding simply through frequent proximity and touching. whydoesdog.com
Social Intelligence & Emotional Sensitivity
Dogs, in general, are highly perceptive of human cues — tone of voice, facial expressions, body language, and even scent changes — and Yorkies often excel at interpreting these signals. Veterinary Care at Your Fingertips
This emotional intelligence leads Yorkies to respond to human mood states, comfort their owners when stressed, and engage socially at a level that deepens trust and attachment. Veterinary Care at Your Fingertips
Evolutionary Co‑Adaptation
Domestic dogs co‑evolved with humans for thousands of years, a process that selected for traits supportive of human companionship, such as reading human signals, reduced fear of people, and cooperation. trustedhousesitters.com
Today, breeds like Yorkies retain this legacy — which means their emotional wiring is already predisposed toward human attachment.
3. Oxytocin’s Role in Deepening the Yorkie Bond
Oxytocin doesn’t just trigger warm feelings — it creates a feedback loop of bonding.
✔ Dog looks at owner → oxytocin rises in both
✔ Owner feels more affectionate → interacts more
✔ Dog responds with attention and trust
This cycle leads to more frequent, more intense attachment behaviors compared to many other human‑animal interactions. Paw’s Academy AU
Research has shown this process is not just behavioral but physiological — meaning the bond has a measurable biological basis. Pettsie
4. Emotional Intelligence: Why Yorkies “Get” Us
Dogs often seem to understand us, and this isn’t just subjective. Researchers have shown that dogs:
✔ Detect human facial expressions
✔ Respond to tone of voice
✔ React to emotional changes in their caregivers
✔ Can act empathetically in stressful situations
This emotional attunement means Yorkies don’t just follow commands — they respond to emotional cues, and adjust their behavior accordingly. Veterinary Care at Your Fingertips
For example, a Yorkie might sense sadness and offer physical closeness, or excite you when you’re happy, reinforcing the emotional bond.
5. Attachment Styles and Yorkie Behavior
Research suggests that the nature of the bond a dog forms with its owner isn’t random. Consistent, predictable caregiving tends to foster a secure attachment, where the dog feels safe exploring the environment and returning to the owner for comfort. Enviro Institute
Conversely, inconsistent or unpredictable caregiving can contribute to insecurity, anxiety, or clingy behavior — often seen in dogs with separation‑related distress. PubMed
This mirrors human attachment theories — dogs form secure or insecure bonds based on caregiving patterns.
6. Social Reinforcement & Conditioning
Positive interactions — play, grooming, training, walks — consistently reinforce attachment. When a Yorkie associates their favorite person with:
✔ Food
✔ Comfort
✔ Play
✔ Safety
✔ Attention
they learn to seek out and prefer that person’s presence. whydoesdog.com
In behavioral psychology, this is a form of operant conditioning, where positive outcomes (attention, treats) strengthen proximity‑seeking behaviors.
7. Genetics, Breed History, and Human Bonding
Beyond specific hormones, genetics also shape how social dogs are. Certain breeds — especially companion breeds like Yorkies — have historically been selected for sociability, attention toward humans, and calmness in domestic environments. trustedhousesitters.com
This doesn’t mean every Yorkie bonds the same way, but the biological predisposition enhances the likelihood of strong attachment.
8. The Role of Owner Interaction and Environment
Consistent, Positive Care Raises Attachment
Dogs bond most strongly when they receive predictable care — feeding, reassuring interaction, play, walks, and training. Consistency builds trust and security, which leads to deep attachment. Enviro Institute
Early Socialization Matters
Early exposure to humans — especially during puppy stages — helps develop social confidence and ease around people, making attachment natural rather than anxious. whydoesdog.com
Owner Personality Influences the Bond
Some studies find that owner temperament and attachment style affect how intensely dogs bond, with greater emotional closeness linked to certain personality traits or emotional patterns in the caregiver. Nature
9. Emotional Needs & What Yorkies Give Back
Yorkies — like other dogs — seek comfort, reassurance, and companionship. In return, they provide:
❤️ Unconditional affection
❤️ Loyal companionship
❤️ Stress reduction for their owners
❤️ Emotional support during tough times
❤️ Motivation for physical activity and routine
This reciprocal emotional benefit reinforces daily bonding and often makes the human‑dog relationship mutually fulfilling. Veterinary Care at Your Fingertips
10. Separation, Distress, and Attachment Intensity
Because Yorkies bond so tightly, many display separation distress when apart from their favorite human.
This isn’t merely “missed you” — research shows dogs with strong attachments may exhibit behaviors suggesting stress or anxiety when alone, which highlights the strength of their bond. PubMed
Understanding these attachment responses helps owners support emotional health — balancing bonding with independence training.
11. Evolutionary Perspectives: Why Dogs Are “Social Glue”
Dogs evolved alongside humans for at least 15,000 years — and possibly much longer. During that time, natural selection favored dogs that were* good at reading human behavior, following cues, and staying socially connected.* trustedhousesitters.com
That evolutionary heritage has shaped dogs into a species uniquely suited to form deep attachments with humans — a trait few other animals exhibit at the same level.
12. Unique Yorkie Traits That Enhance Human Bonding
Yorkies often become velcro dogs — following their favorite person from room to room, curling up at their feet, and engaging in persistent affectionate behaviors. Many owners describe this as deeply personal attachment, where the dog’s behavior shows preference and clear emotional connection.
This level of engagement stems from:
✔ Terrier social drive
✔ Proximity‑seeking behavior
✔ Affection reinforcement over time
✔ Early learning through interaction
These traits make Yorkies not just pets, but emotionally meaningful companions.
13. Real‑World Yorkie Bonding Stories
Owners often report:
-
Yorkies who choose one person in the household to follow everywhere. Reddit
-
Yorkies who greet their favorite human excitedly after even brief absences. Reddit
-
Dogs preferring one caregiver but still bonded to the whole family. Reddit
These stories reflect real attachment patterns shaped by time invested, routines shared, and emotional reinforcement.
14. Are Yorkie Bonds Healthy or Excessive?
Strong attachment isn’t necessarily unhealthy — but balance matters. Dogs that become overly reliant may develop separation anxiety, which owners should address through gradual independence training and confidence building.
A well‑balanced Yorkie bond includes:
✔ Warm interaction
✔ Responsible boundaries
✔ Encouraged independence
✔ Emotional responsiveness
This supports emotional health without stress.

16. The Yorkie‑Human Bond: A Unique Companion Relationship
At its core, the bond between Yorkies and humans is rooted in co‑evolution, social cognition, and mutual emotional reinforcement.
Humans provide care, attention, and structure — and Yorkies respond with loyalty, affection, and social feedback that taps into deep neurological and behavioral wiring.
That’s why Yorkies don’t just live with us — they attach to us, often profoundly and persistently.
