Fox Terrier vs. Rat Terrier

The Fox Terrier: Bold and Spirited

The Fox Terrier is a well-known breed developed in England for fox hunting. Available in both Smooth and Wire coat varieties, Fox Terriers are compact, muscular dogs typically weighing 15–20 pounds.

• Energy Level: Extremely high—Fox Terriers are excitable, playful, and rarely slow down.
• Temperament: Bold, mischievous, and sometimes stubborn. They are intelligent but can be independent thinkers.
• Lifestyle Fit: Best for experienced dog owners who enjoy high-energy, lively pets and have plenty of time for training and exercise.
• Barking Level: High
  Fox Terriers are among the more vocal terriers. Bred as alert hunters, they tend to bark at noises, strangers, and anything that excites them. Without consistent training, they may develop nuisance barking. They’re best for families who don’t mind a chatty companion.

Fox Terriers are fun and charming, but their boundless energy and strong will can be overwhelming for first-time terrier owners. Check out this article for a more in depth look at this breed: Fox Terrier Dog Breed Complete Guide – A-Z Animals

The Rat Terrier: Versatile and Loyal

The Rat Terrier originated in the United States as a versatile farm dog and hunting companion. They are generally smaller than Deckers but larger than Fox Terriers, with sizes ranging from 10–25 pounds depending on lineage.

• Energy Level: Moderate to high—active and playful, but often easier to manage than a Fox Terrier.
• Temperament: Loyal, alert, and eager to please, though they retain classic terrier independence.
• Lifestyle Fit: Well-suited for families who want an energetic but trainable companion with a big heart.
• Barking Level: Moderate
  Rat Terriers are alert watchdogs but generally less vocal than Fox Terriers. They’ll bark when something is unusual or when strangers approach, but with training and socialization, most can learn to quiet down quickly. They’re good for families who want a balance between alertness and peace.

Rat Terriers are intelligent and adaptable, making them a popular choice for families who want a terrier with a bit more balance than the fiery Fox Terrier.

The Decker Terrier: Athletic and Devoted

The Decker Terrier is a selectively bred line of the Rat Terrier, developed for larger size, hunting ability, and versatility. Adults typically weigh 25–40 pounds and are sturdier than standard Rat Terriers.

• Energy Level: High—these dogs love adventure, whether it’s hiking, hunting, or long play sessions.
• Temperament: Loyal, intelligent, and deeply bonded with their families.
• Lifestyle Fit: Best for active families or individuals who enjoy outdoor life and want a devoted, athletic companion.
• Barking Level: Moderate to Low
  Because Decker Terriers are larger and bred with a focus on hunting and companionship, they’re typically less “yappy” than smaller terriers. They will alert-bark when necessary but are not known to be excessive. With proper exercise and training, they are usually quieter than Fox Terriers or standard Rat Terriers.

Unlike the Fox Terrier’s mischievous streak, Decker Terriers are more focused and eager to please, making them excellent working partners as well as affectionate family dogs.

The Old Dominion Terrier: Gentle and Family-Oriented

The Old Dominion Terrier is a developing breed also rooted in Rat Terrier heritage, but with an emphasis on a calmer, family-friendly temperament. Slightly smaller and more refined than the Decker, Old Dominions offer the perfect balance of energy and gentleness.

• Energy Level: Moderate—enjoys activity but settles down easily indoors.
• Temperament: Affectionate, gentle, and adaptable; they thrive in family environments.
• Lifestyle Fit: Ideal for families seeking a loving companion who enjoys playtime but also values quiet evenings together.
• Barking Level: Low to Moderate
  The Old Dominion Terrier was developed with family life in mind, and their temperament reflects that balance. They will bark to alert you, but they tend to settle quickly and aren’t prone to nuisance barking. They’re an excellent choice for families who want an attentive but not overly vocal dog.

For families deciding between a Fox Terrier vs Rat Terrier, the Old Dominion Terrier often represents the best of both worlds: playful without being overwhelming, loyal without being stubborn.
