Author's note: The main pathologies of the Yorkie have already been discussed in more detail in other blog articles. Here, the objective is mainly to place the breed in its global profile and to remind that such a highly sought-after dog deserves real thought about recovery, joint comfort, and long-term effort management.
The Yorkshire Terrier is often reduced to the image of a small, decorative dog.
Yet the FCI standard describes it as an active, intelligent, lively, and balanced toy Terrier, originating from a breed observed as early as the 1850s in Yorkshire.

Reminder: A terrier is a type of dog historically selected to seek, pursue, and dislodge animals living in burrows or hard-to-reach areas: foxes, badgers, rats, pests, rabbits, etc. |
In France, the breed remains well-represented but is significantly declining in the LOF. The Centrale Canine recorded 2,408 registrations in 2024 and 2,163 in 2025, a 10% decrease in one year. In the United Kingdom, the VetCompass study published in 2025 also shows a decrease in popularity in recent cohorts.
Far from its image as a small celebrity dog... It is a lively little dog, attached to its humans, with several well-documented points of vigilance, especially concerning teeth, kneecaps, trachea, and certain congenital conditions.
Quick breed profile
A small, compact English companion terrier, very upright in its stance, with long, fine, silky, non-woolly hair, the Yorkshire Terrier combines small size, strong human proximity, and a more assertive temperament than often imagined. The FCI standard sets a weight of up to 3.2 kg and does not recognize any "teacup" variety.

Origin and Standard
The Yorkshire Terrier originated in Great Britain, more precisely in the same region as the Airedale. The FCI standard indicates that the breed was first observed around 1850.
Its probable origins include the old Black and Tan Terrier, the Maltese, and the Skye Terrier.
The name Yorkshire Terrier was adopted in 1870.

The FCI classifies it in Group 3, Section 4, without a working trial.
The desired dog is compact, clean, very upright in its gait, with long, straight, shiny, fine, and silky hair.
The top of the body should be dark steel blue, with intense fawn markings on the head, chest, and limbs.
The weight should not exceed 3.2 kg.
Daily temperament
The Yorkshire Terrier remains a terrier.
It is lively, curious, alert, close to its humans, often expressive, and quick to react.
Its small size deceives many people... Beyond the small couch dog one might imagine, it is a dog that observes, alerts, forms strong attachments, and can become very vocal or anxious if overprotected or incompletely trained.
The standard also emphasizes its active, intelligent, and spirited nature.
Owner Profile
The Yorkshire is suitable for someone who wants a small dog close to them, lively, involved in household life, but who agrees to provide it with a real framework.
It is well-suited to people in apartments, couples, single individuals, or calm households, provided that its needs for outings, stimulation, and grooming are taken seriously.
It is ill-suited to someone who wants a purely decorative dog, requiring no maintenance, no real training, or ultra-miniaturized for image reasons.
Family life and cohabitation
The Yorkshire Terrier can live very well in a family, but its small size requires caution. With boisterous young children, the risk is also physical: falls, poorly calibrated handling, accidental crushing. With older, respectful children, cohabitation can be excellent.
With other dogs, much depends on socialization.
Some Yorkies are easy-going, others very brave.
Their small size doesn't stop them from believing they are much larger than they are, which can end badly when facing a large or impatient dog.
Physical and Mental Needs
The Yorkshire does not need huge amounts of activity, but it does need a real dog's life.
Daily outings, exploration, smells, interaction, play, a minimum of cognitive occupation: all of this matters. Its small size certainly reduces logistical constraints, but absolutely not its behavioral needs.
A Yorkshire that is not taken out enough, over-carried, kept indoors too much, or left without stimulation can become barky, agitated, more reactive, or harder to manage.
It is not a "complicated" breed in the strict sense, but, like all other dogs, it is not a breed that can be stripped of all canine life without consequences.
Growth
The Yorkshire Terrier grows quickly, but very small individuals remain more vulnerable early in life. The VetCompass 2025 study also shows an interesting point: in the population followed in veterinary practice, Yorkies are on average heavier than the standard's upper limit, with an average adult weight of 5.06 kg.
This highlights a real discrepancy between the standard dog and the companion Yorkshire found in the field.
Health
Periodontal disease
This is the main point of vigilance for the breed. In the VetCompass 2025 study, periodontal disease is the most frequent diagnosis, at 21.10%. Persistent deciduous teeth are also among the frequently reported disorders, at 3.57%.
Patellar luxation
Patellar luxation is a classic predisposition in the Yorkshire Terrier. The VetCompass 2016 study on patellar luxation identifies the Yorkshire among the most affected breeds, and the UFAW clearly recognizes it as a problematic condition in this breed.
Tracheal collapse
Tracheal collapse is a recognized condition in the Yorkshire Terrier. The UFAW indicates that the breed is overrepresented among affected small dogs, with a probable hereditary basis, even if the exact mode of transmission is not established.
Congenital portosystemic shunt
The Yorkshire Terrier is among the breeds strongly associated with congenital portosystemic shunt. Tobias's work shows a strong breed association and also points towards a hereditary basis in the Yorkshire Terrier.
Legg-Calvé-Perthes / Avascular necrosis of the femoral head
Avascular necrosis of the femoral head is one of the pathologies monitored in the Yorkshire Terrier. The UFAW lists it in the breed and emphasizes its severity on locomotor comfort and the growing hip.
Other vigilances
The UFAW also reports other known conditions in the Yorkshire Terrier, notably distichiasis and diabetes mellitus. These may not be the primary concerns in routine practice, but they exist within the breed's health landscape.
What this means practically / prevention
For a Yorkshire Terrier owner, this changes three very practical things.
First, oral health must be taken seriously from an early age: brushing, monitoring of deciduous teeth, regular check-ups.
Next, any limping, discomfort in a hind leg, or abnormal gait should be examined promptly.
Finally, any chronic dry cough, respiratory distress, or exercise intolerance should lead one to consider the trachea rather than dismissing it.
These prevention strategies stem directly from the breed's documented primary weaknesses.
Grooming
The Yorkshire requires proper grooming.
Its long, straight, fine, and silky coat needs regular attention. Many owners opt for a shorter cut to simplify daily management. The standard emphasizes that the coat should never hinder movement.
But the real grooming issue isn't just the coat. It's also the mouth. For this breed, dental hygiene is a serious minimum requirement.
Real cost
The Yorkshire Terrier is not expensive to feed, but that doesn't mean it costs little. Grooming, dental care, veterinary monitoring for locomotor or respiratory problems...
Add to that a potentially overpriced purchase if miniaturization is sold as a premium feature. Be aware that a small size does not protect or exempt you from real maintenance costs!
Legal Framework
In France, the Yorkshire Terrier is not subject to regulations for category 1 or 2 dogs. However, during a transfer of ownership, identification, the transfer certificate, the veterinary certificate, and, more broadly, the mandatory documents related to acquiring a pet dog fall under the general legal framework. The commitment and knowledge certificate must also be provided with a minimum of 7 days before the transfer.
Choosing Your Breeder
When it comes to Yorkshire Terriers, you must avoid the obsession with "always smaller".
The FCI standard sets a maximum weight of 3.2 kg but does not recognize any "teacup" variety. Extreme miniaturization is not a guarantee of quality; it is often a warning sign.
A reputable breeder should be able to speak frankly about a history of patellar luxation, portosystemic shunts, the overall robustness of bloodlines, and the socialization of puppies. The best puppy is not the tiniest. It is one that starts well, comes from consistent selection, and a clean environment.
STOP:We must stop presenting as an asset what often amounts to a deviation.The terms "teacup," "micro," or "pocket" have no serious canine recognition and perpetuate the idea that an ever-smaller dog would automatically be more precious, more desirable, or more exceptional.This is a dangerous logic.Behind this staging of extreme miniaturization is an animal that will have to live with the consequences of essentially aesthetic human choices.It is never the human who suffers in their body from excessive fragility, loss of robustness, or complications linked to over-selection.It is the dog.And when appearance takes precedence over balance, health, and comfort, we leave the realm of taste and enter that of imposed suffering! |
Who it is / isn't suitable for
The Yorkshire Terrier is suitable for people who want a lively, affectionate, engaged small dog with a real personality, and who accept the constraints of grooming and preventive care.
It is not suitable for someone who wants a purely decorative dog, very independent, without an educational framework, or someone who primarily seeks a "teacup" version for image reasons.
