The Shih Tzu boasts one of the most richly diverse color palettes in the entire canine kingdom. From midnight blacks and brilliant golds to intricate parti-color patterns, understanding the genetics and breed standards behind these hues helps owners appreciate their dog’s unique appearance.
Quick Answer: The American Kennel Club recognizes all coat colors and markings in the Shih Tzu breed standard, including solid colors (Black, White, Gold, Red, Silver) and parti-color combinations. Coat colors frequently fade or lighten as puppies mature due to the G-locus progressive graying gene, reaching permanent adult pigmentation around one year of age.
The AKC Breed Standard: Equal Status for All Colors
Unlike breeds where specific colors disqualify a dog from competition, the American Kennel Club (AKC) standard states plainly: “All colors and markings are permissible and are to be considered of equal merit.” In the show ring, a solid gold Shih Tzu is evaluated on the exact same anatomical and movement standards as a tri-colored dog.
The AKC officially recognizes 14 standard coat color combinations:
| Color Classification | AKC Recognized Combinations | Pigment Traits |
|---|---|---|
| Solid Colors | Black, White, Gold, Red, Silver, Blue, Liver | Entire coat is one uniform color with minimal to no white markings |
| Parti-Colors | Black & White, Blue & White, Brindle & White, Gold & White, Liver & White, Red & White, Silver & White | White coat intermixed with patches of a secondary distinct color |
The Critical Role of Skin and Nose Pigment
In the Shih Tzu breed, a dog’s true color classification is determined by the pigmentation of their nose leather, eye rims, lips, and paw pads:
- Black Points: The vast majority of Shih Tzus possess standard black pigmentation. Even if a dog is nearly pure white or deep red, their nose leather and eye rims are jet black.
- Liver (Chocolate) Points: If a dog carries two recessive copies of the brown (b/b) gene, all black pigment in the coat and skin is converted to brown. A liver Shih Tzu will possess a liver-colored or pinkish-brown nose, hazel or amber eyes, and brown paw pads.
- Blue Points: Produced by the dilution gene (d/d) acting on black pigment, giving the skin, nose leather, and coat a distinctive smoky slate-gray or gunmetal cast.
Common Coat Patterns and Markings
Beyond baseline colors, the Shih Tzu coat frequently exhibits striking historical markings:
1. The White “Star of Buddha”
Chinese imperial legends prized Shih Tzus carrying a distinct patch of white hair on the forehead (the “Star of Buddha”) and a white tip on the tail. Myth held that Buddha blessed the dog by placing his finger on its brow.
2. The Black Mask
A deep black or dark shading covering the muzzle, chin, and sometimes encircling the eye sockets, commonly paired with gold or red coats.
3. Brindle
A subtle tiger-stripe pattern of dark brown or black bands alternating over a lighter base color (such as gold, gray, or fawn). Brindle patterns are dynamic and frequently shift as the dog’s undercoat sheds and regenerates.
The Fading Phenomenon: Why Shih Tzu Puppies Change Color
One of the most surprising experiences for new owners is watching a dark, vibrantly marked puppy lighten dramatically over their first year. A jet-black puppy may mature into slate silver, and a rich mahogany red puppy often lightens into a warm honey gold.
This color transformation is caused by the canine progressive graying gene (G-locus) and the natural “clearing” process as the puppy undercoat sheds out to make way for mature adult hair. You can track your puppy’s developmental stages using our Shih Tzu age in human years calculator to determine when adolescent hormone shifts end and final adult pigmentation stabilizes (usually around 12 to 15 months of age).
Styling and Highlighting Coat Patterns
Parti-colored and patterned Shih Tzus look particularly striking when groomed to accentuate their color contrast. A well-scissored face and clean body clip make distinct facial masks and white chest patches stand out.
When trimming your dog at home or specifying styles to a groomer, consult our hair length dog grooming blade chart to choose blade lengths (such as a #4F blade for a plush body or #10 blade for clean facial and sanitary maintenance) that crisp up color lines while keeping the coat silky and manageable.
“Rare” Colors and Marketing Myths
Prospective buyers frequently encounter backyard breeders marketing “rare lavender,” “platinum,” or “isabella” Shih Tzus at exorbitant premiums ($3,000 to $6,000). Exercise extreme caution when shopping for designer colors:
- Lavender / Isabella: Genetically, these are dogs expressing both the liver (b/b) and dilute (d/d) recessive genes, producing a pale silvery-brown coat. While visually unique, breeding solely for dilute recessive genes increases susceptibility to Color Dilution Alopecia (CDA), a hereditary disorder causing hair follicle collapse, dry scaly skin, and permanent hair loss.
- Albino Dogs: Pure white dogs with unpigmented pink noses and red/pink eyes carry genetic albinism, not the standard white coat. Albino dogs suffer from extreme photosensitivity, high risks of ocular cataracts, and elevated skin cancer susceptibility.
Veterinary Disclaimer: Color standards cited in this guide reflect the official criteria of the American Kennel Club (AKC). Coat color has zero influence on canine temperament, cognitive intelligence, or emotional loyalty. If your dog exhibits progressive hair loss along dilute color patches, chronic skin redness, or follicular scaling, consult a licensed veterinarian or a veterinary dermatologist certified by the American College of Veterinary Internal Medicine (ACVIM).
Frequently Asked Questions
What is the rarest Shih Tzu color?
Solid black (with no white hairs) and solid blue (with slate-gray nose and eye rims) are among the least common colors in the breed. True liver-pigmented Shih Tzus with green or hazel eyes are also relatively rare compared to common gold-and-white parti-colors.
Do black Shih Tzus always turn silver or gray?
Not all, but many do. If a black puppy inherits the dominant G-locus clearing gene, their undercoat will begin fading around 6 to 10 months, turning charcoal, pewter, or silver by adulthood. Pure black dogs without the clearing gene remain deep midnight black throughout life.
Does coat color affect a Shih Tzu’s personality?
No. Canine personality and behavioral traits are determined by genetic lineage, early maternal care, and positive socialization during puppyhood. A solid black Shih Tzu has the exact same friendly, affectionate companion potential as a gold-and-white or liver dog.
