Grown Up Yorkie Poo: Size, Temperament, and What to Expect

What Two Breeds Make Up the Yorkie Poo?

The Yorkie Poo (also written Yorkipoo, Yorkie-Poo, or Yorkiepoo) is a designer cross between a Yorkshire Terrier and a Toy or Miniature Poodle. First intentionally bred in the United States during the early 2000s, the Yorkie Poo was designed to combine the Yorkie's bold personality with the Poodle's low-shedding coat. Neither the American Kennel Club nor the UKC recognizes the Yorkie Poo as a standardized breed, so there is no official breed standard governing size, coat, or temperament. That lack of standardization is the single most important thing to understand before bringing one home: every individual dog is a genetic roll of the dice.

Understanding Yorkie Poo Generations: F1, F1B, F2, and Multigen

Because the Yorkie Poo is a designer cross, the generation of breeding dramatically affects what your adult dog will look and act like. Responsible breeders should always disclose which generation they are selling. Here is what those labels mean in practice:

If a breeder cannot tell you which generation a puppy is, walk away. DNA testing through services like AKC-recognized canine DNA panels can confirm parentage, and ethical breeders already do this. An F1 Yorkie Poo from a Toy Poodle parent will look very different from an F1B backcrossed to a Miniature Poodle — the size difference alone can be 5 to 10 pounds.

How Big Will a Grown Up Yorkie Poo Get?

This is one of the most common questions prospective owners ask, and the honest answer is: it depends heavily on which Poodle size was used in the breeding and which generation the puppy belongs to. Below is the realistic range you should plan for.

Most Yorkie Poos bred from Toy Poodles fall in the 5–8 lb range at maturity (around 10–12 months). Those from Miniature Poodle lines can reach 10–14 lb. Puppies typically reach about 75% of their adult weight by 6 months and full adult size by 10–12 months, though some fill out in chest and muscle until 14–16 months.

A practical way to estimate adult weight: Take your puppy's weight at 12 weeks and multiply by 2.5 for a rough projection. A 2 lb puppy at 12 weeks will likely mature to around 5 lb. This is not exact — genetics, nutrition, and generation all influence final size — but it is a reasonable planning tool.

Coat Types and the Hypoallergenic Question

Both Yorkshire Terriers and Poodles are considered low-shedding breeds, and many Yorkie Poos inherit a coat that sheds minimally. However, "low-shedding" is not the same as "hypoallergenic." No dog is truly hypoallergenic — allergies are triggered by dander (dead skin cells), saliva proteins, and urine, not just hair. According to the Merck Veterinary Manual, allergic reactions vary by individual person and individual dog.

Coat Possibilities by Generation

• Straight/Silky (Yorkie-dominant): Fine, flat-lying hair that can grow quite long. More prone to tangling. Common in F1 litters where the Yorkie coat genes dominate.
• Wavy/Fleece: A soft, loose wave that is the most common "middle ground" coat. Easier to maintain than tightly curly hair but still needs regular brushing. Frequently seen in F1 and F1B crosses.
• Curly (Poodle-dominant): Tight curls that shed very little but mat easily if not brushed every 1–2 days. Most common in F1B and multigen puppies backcrossed to Poodles.

Shedding reality check: Even curly-coated Yorkie Poos are not zero-shed. They shed less than a Labrador or German Shepherd, but you will still find some hair on dark clothing. If a household member has severe dog allergies, spend at least 2–3 hours with the specific puppy or adult dog before committing — allergy reactions are too individual to guarantee based on breed mix alone.

Grooming Requirements

Regardless of coat type, a grown up Yorkie Poo requires consistent grooming:

Task	Frequency	Estimated Cost
Brushing (slicker brush + metal comb)	Every 1–2 days for curly coats; 2–3× per week for wavy/straight	$15–$25 for quality brush set
Professional grooming (clip and bath)	Every 4–6 weeks	$50–$90 per session depending on region
Bathing at home	Every 2–4 weeks	$8–$15 for dog-specific shampoo
Ear cleaning	Weekly (Poodle-inherited ears trap moisture)	$6–$12 for veterinary ear cleaner
Nail trimming	Every 2–3 weeks	$10–$20 at groomer or DIY with guillotine clippers
Teeth brushing	Daily (small breeds are extremely prone to dental disease)	$5–$10 for enzymatic toothpaste

Budget roughly $600–$1,100 per year for grooming alone if you use professional services regularly. Home grooming with clippers (e.g., Wahl KM Cordless or Andis AGC2) can reduce this to $200–$400 annually after the initial tool investment of $80–$150.

Temperament: What to Expect From a Grown Up Yorkie Poo

The temperament of an adult Yorkie Poo falls on a spectrum between its two parent breeds, and individual variation is significant. Here is the realistic range:

Best-Case Scenario

A well-socialized Yorkie Poo from a multigen line with Poodle-dominant temperament tends to be affectionate, clever, moderately energetic, and responsive to positive reinforcement training. These dogs excel at learning tricks, enjoy puzzle toys like the Outward Hound Nina Ottosson Dog Brick, and bond closely with their primary person while remaining friendly with visitors.

Challenging Scenario

A Yorkie-leaning F1 with insufficient early socialization may develop excessive barking, resource guarding, nervousness around strangers, and difficulty with house training. Small dogs are often unintentionally reinforced for fearful or aggressive behaviors because owners find it "cute" or harmless — but a Yorkie Poo that snaps at children or lunges at other dogs is just as stressed as a large dog with the same behaviors. Early socialization (before 16 weeks of age) and consistent force-free training using treats and clicker methods are critical.

Health Considerations: The Hybrid Vigor Myth vs. Reality

Let's address a persistent misconception directly: hybrid vigor does not guarantee that a Yorkie Poo will be healthier than either parent breed. The concept of heterosis (hybrid vigor) is real in livestock and has been documented in some canine studies, but it primarily reduces the risk of recessive genetic disorders that require two copies of a faulty gene. It does not protect against conditions that are polygenic (influenced by many genes), structural (related to body conformation), or shared by both parent breeds.

Because the Yorkie Poo inherits genes from both the Yorkshire Terrier and the Poodle, it can inherit health conditions from either side. Here are the conditions to be aware of:

Inherited Health Risks

Condition	Inherited From	Prevalence	What to Watch For
Patellar Luxation	Both breeds	Common in toy breeds — estimated 5–10% of small dogs	Intermittent skipping on hind legs, knee "popping" out of place
Tracheal Collapse	Yorkshire Terrier (high prevalence)	Affects up to 20% of Yorkies by middle age	Dry, honking cough; worsens with excitement or collar pressure
Dental Disease	Both breeds (small mouths = crowding)	Over 80% of small dogs show dental disease by age 3	Bad breath, red gums, reluctance to eat hard kibble
Portosystemic Shunt (PSS)	Yorkshire Terrier	Yorkies are among the most predisposed breeds	Stunted growth, disorientation after eating, seizures
Progressive Retinal Atrophy (PRA)	Poodle	Varies by line; responsible breeders test for prcd-PRA mutation	Gradual night blindness progressing to total vision loss
Legg-Calvé-Perthes Disease	Both breeds (small breed predisposition)	Typically appears between 4–12 months of age	Hind limb lameness, muscle atrophy in one rear leg
Hypoglycemia	Yorkshire Terrier (especially puppies under 4 lb)	Common in toy breed puppies	Lethargy, trembling, collapse — requires immediate glucose and vet care

What responsible breeders do: They perform OFA (Orthopedic Foundation for Animals) patella evaluations on both parents, prcd-PRA genetic testing on the Poodle parent, and cardiac screening. Ask to see documentation before purchasing. A breeder who says "they're healthy, don't worry" without proof is not performing health testing.

When to consult your veterinarian: If your Yorkie Poo develops a persistent cough, limps for more than 48 hours, shows signs of vision changes, or has episodes of disorientation, schedule a veterinary exam promptly. Small dogs can decline quickly from conditions like hypoglycemia or tracheal collapse — early intervention improves outcomes significantly.

Exercise, Training, and Daily Life

A grown up Yorkie Poo typically needs 30–45 minutes of daily activity, split between walks and indoor play. Despite their small size, they are not purely lap dogs — the Poodle heritage gives many of them an active mind that needs stimulation.

Daily Activity Framework

• Morning: 15-minute leash walk (use a harness, never a neck collar, to protect against tracheal collapse)
• Midday: 10–15 minutes of indoor play — fetch, tug, or puzzle feeder
• Evening: 15-minute walk or sniffari (letting the dog lead and explore scents at their own pace)
• Training sessions: 5–10 minutes, 2–3 times per day, using small high-value treats (freeze-dried liver, tiny pieces of boiled chicken)

House training note: Toy and small breeds are notoriously more difficult to house train than larger dogs. Their small bladders fill quickly, and cold or rainy weather often discourages them from going outside. Expect 4–6 months of consistent crate training and scheduled potty breaks (every 1–2 hours for puppies under 4 months). Indoor potty systems like the Fresh Patch real grass pad or UGODOG can serve as a weather backup.

Cost of a Yorkie Poo: Purchase Price and Lifetime Budget

Yorkie Poo puppies are widely available from both breeders and rescues, but pricing varies significantly based on generation, breeder reputation, health testing, and region.

Source	Price Range	What's Typically Included
Responsible breeder (health-tested parents, F1/F1B)	$1,500–$3,500	First vaccinations, deworming, health guarantee, take-back clause, OFA/genetic test documentation
Backyard breeder / online listing	$400–$1,200	Often no health testing, no guarantee, no genetic documentation
Rescue / adoption	$150–$500	Spay/neuter, vaccinations, microchip; adult dogs more common than puppies

First-Year Estimated Budget

Expense	Estimated Cost
Puppy purchase (responsible breeder)	$1,500–$3,500
Veterinary (initial exams, vaccinations, spay/neuter)	$400–$800
Grooming (professional, 6–8 sessions)	$300–$720
Food (high-quality small-breed kibble or fresh food)	$200–$400
Supplies (crate, harness, bed, toys, bowls)	$150–$300
Training (group puppy class or private sessions)	$100–$300
Pet insurance (optional but recommended)	$300–$600/year
Total first year	$2,950–$6,620

After the first year, expect annual costs of $1,200–$2,500 for routine care, grooming, food, and preventive medications. Over a 12–15 year lifespan, total lifetime cost of ownership typically falls between $18,000 and $40,000, depending on health issues and care choices.

When searching for a Yorkie Poo, consider breed-specific rescues like Yorkshire Terrier National Rescue or Poodle rescue networks — mixed-breed dogs from these parents frequently end up in rescue when owners underestimate grooming needs or barking tendencies. Adopting an adult Yorkie Poo lets you see the dog's full-grown size and established temperament, which removes much of the uncertainty of raising a puppy.

Who Is the Yorkie Poo Best Suited For?

After working with dozens of small-breed owners, here is an honest framework for whether this mix fits your household:

Good Fit

• Apartment or condo dwellers — Yorkie Poos adapt well to smaller spaces with daily walks
• Adults or families with children 8+ — older kids who understand gentle handling
• People home most of the day — retirees, remote workers, or households where someone is present for most of the day
• First-time owners willing to invest in training — the Yorkie Poo's intelligence makes them trainable, but their small size means bad habits (barking, biting) are often accidentally reinforced
• People with mild dog allergies — low-shedding coats may work, but always test exposure first

Poor Fit

• Families with toddlers or very young children — a 5 lb dog can be seriously injured by a child who falls on them, squeezes them, or picks them up incorrectly
• Owners away 8+ hours daily — separation anxiety is common and can lead to destructive behavior and excessive barking
• People who cannot commit to regular grooming — matted coats lead to skin infections and pain
• Those wanting a quiet dog — even the calmest Yorkie Poo is more vocal than many larger breeds
