Yorkie Life Stages

Like humans, Yorkies undergo distinct developmental life stages as they age. Understanding where your dog is in their life cycle can provide insight into their equivalent human age and to know how old is my Yorkie in human years? The key Yorkie life stages are:


The puppy stage spans Yorkie years 0-1. Puppies undergo extremely rapid growth and development during this phase. Key puppy milestones include:

  • Weaning off mother’s milk
  • Starting solid foods
  • Learning socialization skills
  • Beginning housetraining
  • Teething

This dramatic developmental period is akin to human infancy. Yorkie puppies require constant care and supervision during these formative early months.


The adolescent phase covers Yorkie years 1-2. This transitional period is similar to the human teenage years. Key adolescent milestones include:

  • Completing immunization schedule
  • Reaching sexual maturity
  • Testing boundaries and independence
  • Establishing adult personality and habits

Adolescent Yorkies exhibit increased stubbornness and selective hearing. Patience and consistency are crucial during this stage.


By 2 years old, Yorkies reach full physical and mental maturity. Key adult milestones include:

  • Settling into adult routines
  • Reaching full height and weight
  • Leveling out of energy and appetite
  • Displaying distinctive adult personality

The adult Yorkie stage is the longest phase, comparable to a human’s 20s through middle age. Providing proper nutrition, exercise and veterinary care during this stage supports longevity.

Formulas for Age Conversion

How do these Yorkie life stages translate into people years? Researchers have devised formulas to calculate approximate human age equivalents:

Puppy Conversion

Yorkie Age 0-1 year: Human equivalent age = Yorkie age x 12

For example:

  • 6 month old Yorkie = 6 months x 12 = 6 human years
  • 1 year old Yorkie = 12 human years

Adolescent Conversion

Yorkie Age 1-2 years: Human equivalent age = 10.5 + (Yorkie age – 1) x 4

For example:

  • 18 month old Yorkie = 10.5 + (1.5 years – 1) x 4 = 18 human years
  • 2 year old Yorkie = 22 human years

Adult Conversion

Yorkie Age 2+ years: Human equivalent age = 24 + (Yorkie age – 2) x 3.5

For example:

  • 5 year old Yorkie = 24 + (5 – 2) x 3.5 = 31 human years

While not exact, these formulas provide a rough guide to correlating Yorkie and human ages based on developmental stage.

This expanded table illustrates the Yorkie-human age alignments from 1-15 years old:

Yorkie Years to Human Years

The table highlights some key patterns in Yorkie aging:

  • The puppy stage is very short, only 1 year
  • They reach adolescence and transition to adulthood quickly
  • The adult phase makes up the majority of the mid-range years
  • Senior status begins around year 7

This provides helpful perspective on where your dog is developmentally based on their age in human years.

What Impacts Yorkie Lifespan?

While these age conversions provide a useful guideline, many factors influence an individual Yorkie’s longevity. Some elements that affect lifespan include:

  • Genetics – Yorkies inherit genetic predispositions from parents that can determine longevity. Responsible breeding maximizes healthy lineage.
  • Nutrition – Providing complete, balanced nutrition tailored for your Yorkie’s life stage supports long-term health.
  • Veterinary care – Routine wellness exams, vaccinations, and prompt treatment of any issues help prevent or mitigate health conditions.
  • Environment – Supplying proper housing, safety precautions, and a stimulating atmosphere contributes to enhanced well-being.
  • Exercise – Regular, moderate exercise aids joint flexibility, cardiovascular function, weight control, and mental engagement – all of which promote longevity.
  • Stress – Preventing chronic stress and anxiety fortifies the immune system and overall health.

With diligent care in these areas, many Yorkies can reach 15+ years of age. But paying attention to their developmental needs is also key.

Caring for Your Yorkie Through Every Life Phase

Your Yorkie’s care should adapt as they progress through each life stage. Here are some tips tailored for each phase:

Puppy Care

Key priorities:

  • Proper nutrition for growth
  • Socialization and training
  • Plenty of play and bonding time
  • Introducing grooming routine
  • Lots of sleep and supervised exploration

Watch for: Fleas/parasites, hypoglycemia, ingesting hazards, adequate bite inhibition with people and animals

Adolescent Care

Key priorities:

  • Consistent training to reinforce manners
  • Regular exercise to burn energy
  • Annual vet exams and preventive care
  • Maintaining healthy diet and weight

Watch for: Roaming/escape attempts, dog fights/injury from excessive rough play, destructive chewing, picky eating

Adult Care

Key priorities:

  • High-quality diet to maintain ideal weight
  • Daily exercise to prevent obesity
  • Mental stimulation like interactive toys and training
  • Semi-annual veterinary checkups
  • Proper dental care

Watch for: Periodontal disease, neurologic issues, cancer later in life

Senior Care

Key priorities:

  • Monitoring for pain, arthritis, declining mobility
  • More frequent veterinary exams to catch issues early
  • Adjusting food for decreased metabolism
  • Providing soft bedding and accessibility accommodation
  • Maintaining relative activity level and mental engagement

Watch for: Heart disease, kidney/liver failure, vision/hearing loss, benign masses, dementia

Tailoring care to your Yorkie’s needs and abilities at each life phase allows you to maximize their quality of life at every age.


Can a Yorkie live to be 20 years old?

It is very rare for a Yorkshire Terrier to live to 20 years old. The typical Yorkie lifespan is 12-15 years. Some may live to 17 or 18 with exceptional care and genetics. Reaching 20 years old is highly abnormal and not to be expected even with the healthiest pedigree. Only a tiny percentage of Yorkies survive beyond 18-19 years. So while technically possible, a 20 year old Yorkie would be extremely unusual.

At what age is a Yorkshire Terrier full grown?

Yorkies are generally considered fully grown between 12-18 months of age. Most Yorkies will reach their full adult size by around 1 year old. However, they may continue filling out and gaining ideal adult muscle tone and coat fullness until approximately 18 months old. Yorkie growth patterns can vary considerably based on their specific hereditary background. But most Yorkies hit full physical maturity before their 2nd birthday.

What age is considered old for a Yorkie?

Yorkies are generally considered to be entering senior status starting around 7-8 years old. This aligns with about 42-45 years old in terms of human years. The senior stage is marked by gradual signs of aging like reduced energy, graying fur, dental issues, and the onset of arthritis. 10 years old is typically deemed the milestone of becoming a “senior” Yorkie. However, smaller teacup Yorkies may transition faster, showing their age sooner. Standard size Yorkies usually remain youthful a bit longer.

Is a 7 year old Yorkie old?

A 7 year old Yorkie is transitioning out of adulthood into senior status. In human years, 7 years old equates to about 41-42 years old, which is nearing middle age. So a 7 year old Yorkie is starting to show signs of aging and is past the prime adulthood stage, but is not considered outright elderly. With good care, a 7 year old Yorkie still has many healthy years ahead even if they cannot match the energy of a 2 year old. At 7, Yorkies enter the phase where closer attention to their changing needs is warranted.

How long do Yorkies normally live?

The typical Yorkshire Terrier lifespan is 12-15 years. Some may exceed 15 years with ideal care and genetics. Large size standards can slightly shorten lifespan. Teacup or miniature Yorkies often live longer than standard sizes.

What causes Yorkies to die young?

Trauma, such as being hit by a car, is the most common cause of premature Yorkie death. Other factors include untreated congenital defects, infectious diseases, cancer, and cardiac issues. Lack of preventive veterinary care also contributes to early demise.

How can I maximize my Yorkie’s lifespan?

Provide excellent nutrition, veterinary care, exercise, grooming and stress management throughout all life stages. Meet their physical and mental stimulation needs at every age. Prioritize preventing and promptly treating any health issues that arise.

What are signs of aging in Yorkies?

Indicators of senior Yorkie status include graying fur, dental issues, weight changes, altered behavior or personality, declining mobility, loss of prior housetraining, clouded eyes, and decreased stamina or appetite. Annual senior bloodwork helps detect internal age-related changes.

Do teacup Yorkies have shorter lifespans?

Yes, teacup Yorkies are more prone to health problems that negatively impact longevity due to their tiny size and fragile bones. Responsible teacup Yorkie breeders screen extensively for genetic issues to maximize healthy outcomes. But standard Yorkies generally live longer than teacup or miniaturized Yorkies.
