If you’re looking for a dog that’s full of energy, intelligence, and charm, the Rat Terrier might be the perfect match. This American breed has a fascinating history as a farm helper and skilled pest exterminator. While small in size, Rat Terriers have big personalities, making them wonderful companions for active families. Let’s dive into everything you need to know about this fun-loving breed—from their looks and personality to their care and health.
A Quick Glimpse at the Rat Terrier
Rat Terriers are compact, muscular, and quick on their feet. They come in two size varieties:
- Miniature: 10–13 inches tall
- Standard: 13–18 inches tall
Their short, shiny coats come in lots of colors, often with large patches of white. From black and tan to blue, lemon, and apricot, every Rattie has its own unique pattern.
Their expressive faces with alert eyes and V-shaped ears (erect, tipped, or button) give them a look that’s both curious and smart—because they truly are!
Personality – Small Dog, Big Heart
One of the most lovable things about Rat Terriers is their affectionate and loyal nature. They love their families deeply and often follow their favorite person around the house.
- With family: They’re warm, playful, and affectionate.
- With strangers: They can be cautious and bark to alert you of new people.
- With kids: Great companions if raised and socialized properly.
- With other pets: Best suited for households without small pets like rabbits or hamsters due to their high prey drive.
They’re fearless, inquisitive, and always ready for fun.
Exercise and Energy
Rat Terriers are not couch potatoes! They need 30–40 minutes of daily exercise to stay happy and healthy. Walks, jogs, or energetic play sessions like fetch are perfect.
They’re also naturals at dog sports like agility, which challenges both their body and mind. Without proper exercise, a bored Rattie may turn to digging, chewing, or barking—so keeping them active is key.
Training and Mental Stimulation
Ratties are smart and eager to learn, but they can also be a little stubborn (thanks to their terrier side). The good news is, they respond wonderfully to positive reinforcement training—think treats, praise, and fun games.
Early puppy socialization is important so they grow up confident and well-mannered around other dogs and people.
Interactive toys, puzzle feeders, and training sessions keep their sharp minds busy and prevent mischief.
Grooming – Easy Maintenance
One of the best things about Rat Terriers is their low-maintenance coat. A quick weekly brushing keeps their fur smooth and glossy. They do shed more during seasonal changes, so you might need to brush them more often at those times.
Other grooming needs include:
- Dental care: Brush their teeth a few times a week (daily if possible).
- Nail trimming: Keep their nails short to avoid discomfort.
- Ear cleaning: Weekly checks to prevent infections.
Common Health Concerns
Rat Terriers are generally a hardy breed with a long lifespan (12–18 years). However, like all dogs, they can be prone to certain health conditions:
- Joint problems: Hip dysplasia, patellar luxation, and Legg-Calvé-Perthes disease.
- Skin issues: Allergies or mite-related conditions like Demodicosis.
- Eye disorders: Primary lens luxation (PLL) and other vision problems.
- Heart disease: Such as mitral valve disease.
- Dental disease: Common if dental care is neglected.
- Epilepsy: Some may inherit seizure disorders.
Regular vet checkups, a balanced diet, and preventive care go a long way in keeping your Rattie healthy.

Rat Terrier Cost
The price of a Rat Terrier can vary depending on factors like breeder reputation, pedigree, location, and whether the pup is bred for companionship or show. On average, you can expect to pay anywhere from $400 to $1,000 for a well-bred Rat Terrier puppy. Puppies from champion bloodlines or top breeders may cost even more.
But remember, the true cost of owning a Rat Terrier goes beyond the purchase price. Essentials like quality food, vet visits, vaccinations, grooming, and training add up over the years. The good news? Rat Terriers are generally healthy and low-maintenance, which can help keep long-term expenses manageable.
Rat Terrier Food
With their playful spirit and high energy levels, Rat Terriers need the right food to keep them healthy, strong, and active. A balanced diet rich in lean protein, healthy fats, and essential vitamins supports their muscular build and keeps their coat shiny. High-quality dry kibble designed for small, active breeds works well, but you can also include fresh foods like cooked chicken, salmon, rice, sweet potatoes, or leafy greens as tasty additions.
Since Rat Terriers can be prone to dental problems, crunchy kibble or dental chews help keep their teeth clean. Watch their portion sizes too—they love food and can gain weight quickly if overfed. Always provide fresh water, and avoid harmful foods like chocolate, grapes, onions, or fatty scraps.
Rat Terrier Breeders
Choosing the right Rat Terrier breeder is just as important as choosing the dog itself. A responsible breeder doesn’t just sell puppies—they care about the breed’s health, temperament, and future. The best breeders raise their Ratties in loving, clean environments and make sure pups are well-socialized before going to their new homes.
When looking for a breeder, keep these tips in mind:
- Health first: Ask for health clearances on common Rat Terrier issues like hip dysplasia, PLL, and heart conditions.
- Meet the parents: A puppy’s behavior often reflects its parents. Meeting them gives you insight into what your pup might be like.
- Ask questions: Good breeders are transparent and happy to answer your concerns about diet, care, and puppy upbringing.
- Avoid puppy mills: Choose breeders who prioritize welfare over quick sales.
Rat Terrier Life Expectancy
The Rat Terrier is a small but sturdy breed with an impressive life expectancy of 12 to 18 years. With proper care, some even live beyond that, rewarding their families with nearly two decades of love and loyalty. Their active lifestyle and hardy genetics contribute to their longevity, but regular vet checkups, a balanced diet, and daily exercise play a big role too. These little dogs not only live long but also stay playful and energetic well into their senior years—making every day with them a joyful adventure.
Brown Rat Terrier
Among the many coat colors of this lively breed, the Brown Rat Terrier stands out for its warm, earthy tones and striking appearance. Whether in solid shades, mixed with white patches, or combined with tan markings, their sleek brown coats highlight their muscular, athletic build. But their beauty isn’t just skin-deep—Brown Rat Terriers are every bit as intelligent, playful, and loyal as their multi-colored cousins.
With their sharp minds, endless energy, and affectionate nature, these brown-coated charmers are just as happy chasing a ball in the yard as they are cuddling on the couch. If you’re looking for a dog that’s both handsome and full of heart, the Brown Rat Terrier is a perfect choice.
Long Haired Rat Terrier
While most people picture the Rat Terrier with its smooth, short coat, some can carry a long-haired variation that gives them a softer, fluffier look. These long haired Rat Terriers are rare but adored for their unique charm. Their flowing coat adds elegance without taking away the classic traits of the breed—intelligence, playfulness, and loyalty.
Caring for a long-haired Rat Terrier means a little extra grooming compared to their short-coated cousins. Regular brushing helps prevent tangles and keeps their fur looking shiny and healthy. But personality-wise, they’re every bit the lively, affectionate, and adventurous Rattie that families love.
Rat Terrier Size
Rat Terriers may be compact, but don’t let their size fool you—they’re packed with energy and confidence! This breed comes in two main varieties: the Miniature Rat Terrier, standing about 10–13 inches tall, and the Standard Rat Terrier, which ranges from 13–18 inches. Most weigh between 10 to 25 pounds, making them the perfect blend of small enough for apartment living yet sturdy enough for outdoor adventures. Their balanced, muscular build allows them to run, jump, and play with incredible agility.
Rat Terrier Chihuahua Mix Puppies
If you think Rat Terriers are full of life, wait until you meet the Rat Terrier Chihuahua mix puppies—often called Rat-Chas. These little bundles of joy combine the bold confidence of a Chihuahua with the playful energy and intelligence of a Rat Terrier. The result? A pint-sized pup with a huge personality!
Rat-Cha puppies usually stay small, making them perfect for apartment living, but don’t be fooled by their size—they’re curious explorers, quick learners, and love being the center of attention. With early training and socialization, they grow into affectionate companions who are both loyal lapdogs and spirited playmates.
