How Nyxborn Interprets the Breed Standard

While the official text provides the foundation, we believe transparency and explanation help owners and future breeders truly understand what “correct” looks like.

Here’s how Nyxborn applies the standard to our own dogs:

Correct Breed Type: Presence, Balance & Identity

Breed type is the essence of what makes a Tibetan Mastiff instantly recognisable.

At Nyxborn, our dogs consistently demonstrate:

A powerful, athletic silhouette
Masculine or feminine expression appropriate to sex
Balanced proportions
Classical Tibetan Mastiff outline
Correct coat texture and density

Dogs like Pythor and Marmie embody this timeless type with clarity and consistency.

Structure & Movement in Line with the Standard

A Tibetan Mastiff is not merely a large dog — it is a functional guardian.
Correct structure ensures:

Strong bone without heaviness
Balanced angulation
Efficient, ground-covering movement
Strong topline and clean gait
Long-term joint soundness

We do not breed exaggerated or unstable dogs.
Every Nyxborn male and female must demonstrate movement and structure suitable for a working guardian.

You can see examples of this on our Our Males and Our Females pages.

Head, Expression & True Mastiff Presence

The head of a Tibetan Mastiff should be noble, expressive, and powerful without being coarse.

Our dogs strive for:

Correct skull proportions
Calm, intelligent eyes
Proper ear placement
Strong muzzle
A steady, observant expression

These features are not cosmetic — they are tied directly to correct structure, health, temperament and breed identity.

Guardian Temperament: Calm, Stable & Rational

The Tibetan Mastiff is an ancient guardian breed.
The standard describes a dog who is:

Calm
Observant
Independent yet bonded
Rational, not reactive
Steady under pressure
Reserved but not unstable

We are proud that Nyxborn dogs demonstrate:

Clear-headed guardian instincts
Confidence without hypervigilance
Neutral, stable behaviour in new environments
Predictable responses around visitors
Excellent recovery after surprises

Every puppy is evaluated through modern, ethical behavioural assessments — more details on our Temperament Testing page.

Health Testing & Soundness

A correct Tibetan Mastiff must be structurally and genetically sound.

Each Nyxborn breeding dog completes:

Hip & elbow scoring
Cardiac checks
Thyroid testing
Structural assessment
Temperament evaluation

This ensures our dogs not only match the written standard — they thrive within it.

You can learn how these qualities shape our program on the Puppy Raising Program page.

We evaluate potential pairings with long-term goals in mind:

Strong breed type
Low health risk

Only dogs who excel across all categories are used in our rare, intentional litters.

These critiques highlight:
