About the Rat Terrier
The Rat Terrier is an American-bred farm dog developed to be the ultimate vermin hunter and all-around farm companion. President Theodore Roosevelt is credited with naming the breed after his own terrier cleared the White House of rats. Rat Terriers are versatile, intelligent, and sturdy little dogs with a smooth coat and elegant, athletic build. They come in miniature and standard sizes and are known for their remarkable pest-control abilities, often clearing farms of rats faster than any other method. They are lively, affectionate, and surprisingly sensitive family companions.

Frequently Asked Questions
- Rat Terriers are excellent family dogs, especially for active families. They are affectionate, loyal, and form strong bonds with all family members. Unlike some terriers that bond primarily with one person, Rat Terriers are generally sociable with the whole family. They are patient with children when properly socialized, though their small size means very young children should be supervised to prevent accidental rough handling. Rat Terriers are sensitive dogs that thrive on companionship and do not do well when left alone for extended periods.
- Rat Terriers are one of the longest-lived dog breeds, with a typical lifespan of 12 to 18 years. Many individuals reach 15 to 16 years, and some live past 18. Their longevity is attributed to their relatively diverse gene pool, sturdy constitution, and small to medium size. Maintaining a healthy weight, regular dental care, and routine veterinary checkups all contribute to maximizing their impressive lifespan. Their long life expectancy is one of the most appealing aspects of the breed for families looking for a long-term canine companion.
- Rat Terriers generally get along better with other dogs than many terrier breeds. They are social dogs that often enjoy having canine companions, especially other Rat Terriers. Early socialization helps them develop good dog-social skills. However, they retain terrier assertiveness and may not back down from confrontations with much larger dogs, so monitoring interactions is important. Their prey drive means very small pets like hamsters, rabbits, and birds are at risk. With cats, early introductions and supervision are key — some Rat Terriers coexist well with cats while others do not.
