Ownership Journey
Do's and Don'ts
| Provide daily exercise — both physical and mental | |
| Use positive reinforcement training methods | |
| Socialize early with other dogs and people | |
| Give them a job — they thrive with purpose | |
| Supervise around small pets due to prey drive | |
| Expect them to be lap dogs — they need activity | |
| Leave them alone too long — they get destructive | |
| Trust them off-leash in unfenced areas | |
| Ignore their barking — it signals boredom |
💡 Rat Terriers are among the most versatile small breeds — they excel at agility, obedience, barn hunt, and are equally happy as farm dogs or apartment companions with sufficient exercise.
⚠️ Their strong prey drive means Rat Terriers may chase cats, squirrels, and small dogs. Early socialization and a secure fence are essential. They are not reliable off-leash.
Rat Terrier: The Versatile American Farm Dog
Theodore Roosevelt reportedly gave the Rat Terrier its name after his own terriers cleared the White House of rats. These are quintessentially American dogs — practical, adaptable, and built for work — who have transitioned beautifully into family companion life without losing their personality or drive.

Temperament
Rat Terriers are spirited, curious, and deeply social. They bond strongly with family and typically get along with other dogs. Their prey drive is substantial — squirrels, rabbits, and sometimes cats are not safe around an unsupervised Rat Terrier. Early introduction and individual assessment are essential when introducing to small animals.
Training
Rat Terriers are intelligent and respond very well to positive reinforcement training. Their terrier independence means they need consistent rules, but they are not stubborn in the way some terriers are — they genuinely want to engage and cooperate. Excellent candidates for agility, nose work, and scent tracking.
Health
Among the healthiest of terriers. Primary concerns include patellar luxation (kneecap dislocation) and hip dysplasia, though rates are lower than many breeds. Their longevity — regularly reaching 14–18 years — is exceptional among all dog breeds.
Frequently Asked Questions
Are Rat Terriers good family dogs?
Yes. Rat Terriers are affectionate, playful, and good with children. They are adaptable to apartment life with adequate exercise. Their terrier tenacity requires consistent training from puppyhood, but they are highly intelligent and respond well to positive reinforcement.
Do Rat Terriers bark a lot?
They can. Rat Terriers are alert and will bark at anything novel or suspicious. This makes them effective watchdogs but can be challenging in apartment settings without consistent training to manage barking on cue.
How much exercise does a Rat Terrier need?
Moderate to high — at least 45–60 minutes of active play or brisk walking daily. They are energetic and curious dogs who need outlets for their intelligence. Puzzle feeders, nose work, and agility are excellent activities for this breed.
