Rat Terrier Colors & Coat Guide
All recognized Rat Terrier colors, coat types, genetics, and how color can impact pricing and health.
The Rat Terrier belongs to the Terrier group and originates from United States. Adults typically weigh between 10 and 25 pounds, standing 10 to 18 inches at the shoulder. Life expectancy runs from 12 to 18 years, and the figures on this page describe that range rather than a single average, because the spread is what matters when you are deciding. Running costs settle around $117 a month once the dog is past puppyhood, before insurance and before anything unexpected. These numbers come from published breed standards and, where a standard is silent, from longevity and veterinary studies; they describe the breed as a population and not the dog in front of you. Line, upbringing, early socialisation and simple chance move an individual well away from the typical profile, and two dogs of the same breed often differ more than two dogs of different breeds. Nothing here is a diagnosis: for a specific animal, a veterinary surgeon who has examined it will always know more than a table.
Rat Terrier Colors Overview
The palette of Rat Terrier coat colors reflects the breed's genetic diversity. Always predominantly white with colored patches, their diverse color genetics include black, tan, chocolate, blue, lemon, and apricot in various combinations..
Responsible breeders prioritize health over color production. While rare colors may be appealing, they should never come at the expense of proper health testing and breed-standard temperament.
All Rat Terrier Colors
The Rat Terrier is recognized in 7 color variations. Standard colors are those accepted by major kennel clubs for conformation showing, while non-standard colors may occur naturally but are not eligible for the show ring. Both standard and non-standard colored Rat Terriers make equally wonderful companions.
Standard vs Non-Standard Rat Terrier Colors
Standard colors (7): White and Black, White and Tan, White, Black and Tan, Blue and White, Red and White, Lemon and White, Chocolate and White. These colors are accepted by the AKC and other major kennel clubs for conformation competition. Standard-colored Rat Terriers are typically priced within the normal $600–$1200 range.
How Color Affects Rat Terrier Price
| Standard colors | Normal pricing ($600–$1200) |
| Rare/unusual colors | Premium pricing (+$360–$600) |
While color can influence the price of a Rat Terrier puppy, prospective owners should prioritize health testing, breeder reputation, and temperament over coat color. A responsibly bred Rat Terrier in a common color with comprehensive health clearances is a better investment than a "rare" colored puppy from untested parents. The base price range for Rat Terriers is $600–$1200, with color-based premiums adding to that range for certain variations.
Rat Terrier Coat Type and Grooming
The Rat Terrier's short, smooth, and dense coat requires grooming appropriate to its texture and density. With grooming needs rated 1/5 and shedding at 3/5, owners should plan their maintenance routine accordingly.
The Rat Terrier's low-maintenance coat is one of the breed's practical advantages. Weekly brushing removes dead hair and promotes skin health, while baths are needed only when the dog is dirty or every 6–8 weeks. Grooming costs are modest at $64–86 per month, and most routine grooming can be handled at home with basic tools.
Regardless of coat color, all Rat Terriers benefit from regular nail trimming every 2–3 weeks, ear cleaning weekly (especially for breeds with floppy ears), and dental care including brushing three or more times per week. These basic grooming tasks prevent common health problems and keep your dog comfortable.
Rat Terrier Coat Genetics
Rat Terrier coat color is controlled by several genes that determine pigment production and distribution. The primary genes include the E (extension) locus, A (agouti) locus, K (dominant black) locus, and B (brown) locus.
DNA color testing is available and can help breeders predict puppy colors and identify carriers of recessive genes. Always predominantly white with colored patches, their diverse color genetics include black, tan, chocolate, blue, lemon, and apricot in various combinations..
Rare vs Standard Rat Terrier Colors
Among Rat Terriers, the standard colors (White and Black, White and Tan, White, Black and Tan, Blue and White, Red and Wh) are most common. With 7 recognized colors, variety exists even within the standard palette. Buyers should be cautious, extremely rare colors can sometimes be associated with health issues or may indicate crossbreeding.

Do Rat Terrier Colors Change with Age?
Many Rat Terrier puppies experience some degree of color change as they mature. Puppies may be born darker or lighter than their adult coat. Standard colors (White and Black, White and Tan, White, Black and Tan, Blue a) typically stabilize as the puppy coat transitions to the adult coat between 4 and 12 months of age.
Choosing a Rat Terrier by Color
When selecting a Rat Terrier puppy, coat color is one of the most visible factors, but it should be among the last in your decision-making process. Here is a practical framework for evaluating color alongside more important factors:
- Health testing comes first: Both parents should have documented clearances for breed-relevant conditions including Patellar Luxation. No color is worth compromising on health documentation.
- Temperament matters more: Meet the puppies and both parents when possible. A well-socialized puppy with stable temperament from health-tested parents in a common color outweighs a "rare" colored puppy from an unknown background.
- Breeder reputation is essential: Reputable breeders prioritize producing healthy, well-tempered puppies and are transparent about all aspects of their program. They do not market "rare" or "exotic" colors at inflated prices.
- Then consider color: Once health, temperament, and breeder quality are confirmed, choose the color that appeals to you. All 7 recognized Rat Terrier colors can produce healthy, happy companions.
Controversial Colors
In the Rat Terrier world, so-called 'rare' colors can be controversial. The breed standard recognizes colors like White and Black, White and Tan, White, Black and Tan, Blue a, and deviations may involve genes associated with health problems. Breeders who focus on color over health may cut corners on testing for Patellar Luxation and Legg-Calve-Perthes Disease.
