What You Should Know Before Adopting a Rat Terrier

The Rat Terrier might be small, but don’t let that fool you — this little dog is packed with personality, energy, and a surprising amount of brains (sometimes too much for their own good!). I've had the chance to work with a few over the years, and I can tell you: they’re not for everyone, but if they are for you, they’re unforgettable.

Here’s what you should really know if you're thinking of bringing one into your life:

They’re Smart — But Also Super Stubborn

Rat Terriers are clever. Like, "figure out how to open the treat jar and escape the yard" clever. But with that smarts comes a strong will. Training can be a challenge, especially if you expect them to just obey because you said so. You’ll need patience, consistency, and a big sense of humor. Use positive reinforcement, keep things interesting, and don’t expect instant results — they’ll get it, but on their terms.

They Love Their People (But Don’t Expect a Couch Potato)

Rat Terriers are loyal, affectionate, and thrive with their family. But they’re not snuggle-all-day lap dogs. They’d much rather be chasing something, solving a puzzle toy, or trying to dig a tunnel in your backyard. If you’re active and enjoy engaging with your dog, they’ll become your tiny shadow.

Socialization Is Key

Early and ongoing socialization is a must. While they can be friendlier than some other terriers, they still have a strong prey drive and a tendency to be wary of strangers or unfamiliar pets. Introduce them early and often to people, dogs, and different environments. With cats or small animals, be extra cautious — their instinct to chase is real.

They Need Both Physical and Mental Workouts

A tired Rat Terrier is a happy (and well-behaved) Rat Terrier. Aim for 40–60 minutes of daily exercise, split into a couple of walks or play sessions. Puzzle toys, scent games, and training drills help satisfy their busy brains. A bored Rat Terrier will find something to do — and you probably won’t like it (chewing, barking, digging... you get the idea).

Yard time can help, but make sure it’s escape-proof. These dogs are known for their digging and climbing skills when something catches their attention.

Barking and Digging? Yeah, That’s Part of the Package

Barking and digging come with the terrier territory. You can reduce it with exercise, mental stimulation, and training, but don’t expect to eliminate it completely. If you’ve got a prized garden or you’re sensitive to noise, this isn’t the breed to "fix" — it’s the breed to work with.

Don’t punish unwanted behaviors — that’ll just create friction. Instead, redirect them, offer better alternatives, and reward the behavior you do want. It’s a game of consistency.

They Don’t Like Being Left Alone for Long

Rat Terriers are pretty attached to their people. Leave them alone too long and you might come back to chewed furniture or noise complaints. If you’re often out, consider a dog walker, a second dog, or someone else at home to keep them company. And always leave them with something to do when you're gone — stuffed Kongs, puzzle toys, etc.

Grooming Is a Breeze

Good news: grooming is low-maintenance. Their short coat doesn’t shed much and doesn’t require fancy upkeep. A quick brush every now and then, basic dental care, nail trims, and ear checks — that’s about it.

They’re Tough Little Dogs, But Still Need Care

Rat Terriers are generally healthy and can live up to 18 years with good care. That’s a long commitment! Like any breed, they’re prone to a few issues like hip dysplasia, allergies, or patellar luxation. Choose a responsible breeder or adopt from a rescue that shares full health info, and keep up with regular vet visits.

Bottom line? Rat Terriers are energetic, clever, and full of personality — but they’re not a low-effort dog. If you’re active, patient, and up for the challenge, you’ll get a loyal and endlessly entertaining companion. But if you’re looking for a laid-back, go-with-the-flow pup, this breed might run circles around you — literally.

Choose wisely, and if you do bring a Rat Terrier home, get ready for a fun, wild ride.
