“Tough as nails.” That’s how the United Kennel Club (UKC) describes the Patterdale Terrier. These doughty dogs were bred for vermin hunting, which explains both their tenacious temperament and their small stature that’s perfect for tunneling. They are down for anything, including going down under the ground.

As you might have guessed, dogs with the smarts, energy, will, and grit to track down prey may not be a good fit for every home. Though they love their families and aim to please, Patterdale Terriers naturally follow their own instincts and will need consistent positive-reinforcement training to learn otherwise. 

Patterdale Terrier Characteristics

Remember: Dogs are individuals and not all dogs, even those of the same breed, will exhibit all the same qualities.

    Patterdale Terrier Appearance

    The Patterdale Terrier dog was built to work and isn’t afraid to show it. According to the breed standard, “the Patterdale is a hunting terrier designed to confront quarry directly in tight and challenging quarters.”

    They’re compact because their size is vital to their tunneling work. In fact, the breed standard notes that your hands should be able to span the circumference of the Patterdale’s chest.

    1. Ears

      The Patterdale Terrier has small, triangular ears that fold down, with the tips resting near the outside corners of their eyes.

    2. Eyes

      Eye color is dependent on coat color. Chocolate Patterdales have amber-colored eyes, while all other Patterdales have brown eyes.

    3. Nose

      Nose color is similarly related to coat color. Chocolate Patterdales have brown (also referred to as red) noses, while other Patterdales typically have black noses.

    4. Coat Length

      Patterdales have three different coat types: smooth, broken, and rough. Smooth-coated Patterdales have very short, smooth fur; broken-coated Patterdales have longer hair on their bodies; and rough-coated Patterdales have longer hair overall.

    5. Coat Color

      The breed’s coat comes in shades of black, red, chocolate, and black and tan. Some may have small white markings on their chest and feet.

    6. Tail

      Patterdales have high-set tails. The breed club standard mentions docking, which involves cutting off a portion of the dog’s tail as a puppy. However, this is a controversial procedure that many veterinary groups, as well as some states and countries, have banned. If you have questions about this procedure, speak with your veterinarian.

    Patterdale Terrier Temperament

    Per the UKC breed standard, the Patterdale Terrier is “not a dog for the average pet owner.” Understanding their original purpose sheds light on this cautionary designation. 

    Patterdale Terriers were bred to serve as go-to-ground hunting dogs (i.e., dogs who would root out vermin from underground tunnels and dens). And many of the characteristics that help them excel at their job don’t always translate well to family life. 

    For example, Patterdales have a high prey drive. But while they don’t mix well with vermin (and may view small animals like cats, gerbils, and guinea pigs as something to chase after), Patterdales can live harmoniously with other dogs and with larger animals like livestock.

    Despite their working-dog instincts, Patterdales form loyal, affectionate bonds with their families and have a strong desire to please. However, the Patterdale Terrier Breed Club does not recommend the breed as a playmate for children younger than 7 years old. To be met with gentleness, children must first know how to treat dogs with gentleness

    But with the right family, in the right environment, and with dedicated training and socialization, a Patterdale Terrier can thrive.

    How to Care for a Patterdale Terrier

    Because Patterdale Terriers have insatiable appetites for action, most of their care needs revolve around keeping their minds and bodies engaged. As the breed club puts it: “These dogs require an extraordinary amount of human attention, outdoor activity, exercise, discipline, and an understanding of their hunting nature.”

    And because they have a typical terrier dog temperament, all that care should be paired with a healthy sense of humor.

    Patterdale Terrier Health

    The Patterdale Terrier is a generally healthy breed with an average lifespan of 10–12 years. But like all dogs, they are prone to develop certain health conditions. It’s important to partner with an ethical breeder who prioritizes health and genetic testing.

    Patterdales are particularly at risk for:

    • Primary lens luxation: Primary lens luxation (PLL) is when the eye lens moves from its normal position, and it can affect one or both eyes. The condition can cause redness, tears or discharge, cloudiness, and pain and can lead to inflammation, glaucoma, and even blindness. If caught early, surgical lens removal is an option. Otherwise, medication can be used to alleviate pain and discomfort. 
    • Patellar luxation: A patellar luxation occurs when the patella (or kneecap) moves outside of its normal groove in the thigh bone. Signs include limping, bunny hopping, and a popping sound from the knee joint. Dogs with severe cases of patellar luxation may need surgery. 
    • Periodontal disease: Periodontal disease occurs when bacteria builds up in your dog’s mouth, damaging the teeth, gums, jaw bone, and other tissues. While the disease is common in dogs of all sizes, it is particularly common in smaller breeds. Signs of periodontal disease include plaque and tarter buildup, gum irritation, bad breath, missing teeth, and root exposure. Treatment can involve professional cleaning, extractions, or both. 

    Patterdale Terrier History

    The Patterdale Terrier is a rare dog breed and is not yet recognized by the American Kennel Club (AKC). However, the breed has been part of the United Kennel Club (UKC) since January 1, 1995.

    According to the UKC, the Patterdale is mainly descended from the Fell Terrier, a small working dog from Northern England. Like Patterdales, Fell Terriers were bred to hunt and confront vermin.
