Daily activity how busy a day looks

High energy. Daily walks plus play and brain games keep it content; it enjoys agility, obedience and scent work.4

Grooming and care the hands-on bits

Low-maintenance coat: a weekly brush and a bath now and then, with regular nail trims.4

Home where they are happiest

Adapts to many homes if exercised; a secure yard helps, as a bored Rattie may dig.4

Food basics what goes in the bowl

A good-quality complete food suited to small, active dogs, fed in measured meals rather than left out all day.4

Company who they like around

Family-oriented and affectionate with its people; it does best with company and clear, consistent routines.42

The story where it all began

Rat Terriers grew out of the terriers that working-class British immigrants brought to America, mixed from Smooth Fox, Manchester and the old English White Terrier. Later crosses with Whippets, Italian Greyhounds and Beagles added speed and scenting ability, and the breed became a fixture on family farms in the 1920s and 1930s.21

A day in the life told by a Rat Terrier

I wake up with the sun, my nose twitching at the promise of adventure. After a quick breakfast, I patrol the yard, checking every corner for intruders, squirrels, leaves, the occasional daring butterfly. My humans laugh as I pounce on a dandelion. Later, we play hide-and-seek with a squeaky toy, and I win every time. In the afternoon, I practice my agility moves on the lawn, leaping over sticks like a champion. When evening comes, I curl up on the couch, my head on a warm lap, dreaming of tomorrow's treasures. Life is a game, and I'm the best player.

A made-up story, just for fun. Not advice of any kind.

The care rhythm a typical week and year

A typical home-care rhythm for a Rat Terrier. A starting point, not a vet's advice.

Treats they will love homemade and simple

Rat Terrier tip

Rat Terriers are prone to weight gain and skin allergies, so choose low-calorie, fish-based treats and keep portions tiny. Because dental disease is very common in this breed, opt for dental chews or crunchy treats that help clean teeth, and always ask your vet for advice on managing allergies or weight.
