Breed Summary
Rat Terriers are the quintessential all-American dog, beloved for their lively personality and versatile abilities. Originally bred as farm dogs and hunting companions, these agile and intelligent pups are excellent at chasing down pests (hence the name!) and excel in various canine sports and activities. Despite their working-dog history, they also make fantastic house pets, forming strong bonds with their families and thriving on attention and playtime.
Small but sturdy, Rat Terriers weigh between 10 to 25 pounds and are known for their lean, athletic build. Their short, sleek coats are low-maintenance, though their high energy levels mean they need plenty of exercise to stay happy and fit. While Rat Terriers are adaptable to many living situations, from rural farms to urban apartments, they thrive in environments that provide ample physical and mental stimulation. Their curious, clever nature and strong prey drive make them a joy for active families who can keep up with their adventurous spirit.
Vet's Note
Rat Terriers are generally healthy, but like all breeds, they have specific concerns. They can be prone to patellar luxation (knee issues), which makes joint-supportive nutrients like glucosamine beneficial. Some Rat Terriers also have sensitivities to certain foods, requiring a balanced diet with high-quality proteins and minimal fillers. Their active lifestyle necessitates a diet rich in energy-dense nutrients to support their muscles and metabolism.
Health Considerations
-
Bone & Joint
It’s very common for breeds like the Rat Terriers to develop discomfort or pain in their joints and bones, especially as they age. Some of these issues are hereditary, and some come from wear and tear over time. We can’t usually prevent these problems, but proper nutrition and weight management will do wonders in minimizing pain in our beloved pets. We always make sure diets include the ingredients below.

Cognitive
Puppy and senior Rat Terriers need a little extra brain power in their nutrition plans.

Dental
A Rat Terrier's teeth and gums are always under plaque attack, which forms naturally from food particles and other bacteria.

The only thing better than looking into your Rat Terrier’s eyes is looking into your Rat Terrier’s healthy eyes.

Are Fresh Food Diets Good for Rat Terriers?
Only if they’re properly balanced.
Many well-intentioned Rat Terriers parents spend a lot of time preparing meals at home, but health benefits are lost if meals aren’t properly portioned and balanced with all the nutrients dogs need. Recently, a few companies have done an excellent job ensuring accurate portions and nutrient balance by delivering pre-prepped fresh meals customized to the size and needs of your dog. Farmer’s Dog, Ollie and Nom Nom have each been approved by our nutrition team as delivering truly quality and well-balanced meals. They can be a little expensive (usually 3-4x more per day than kibble), but many find the added health benefits worth the cost. They do offer discounts to new customers, though, if you’d like to try one out.

Foods We Recommend for Rat Terriers Puppies
How long do Rat Terrierss need puppy food?
Until they're 10 to 12 months old.
Rat Terriers are very focused on growing, and how we feed them should help them do just that. Since they have so much growing to do, they need higher amounts of nutrients than adult dogs, especially proteins, fats, carbohydrates, vitamins, minerals and — don’t forget — water. It’s still important to not overfeed puppies, so make sure to portion food and keep treats to no more than 10% of their caloric intake. Since balance is so important, we recommend that your young Rat Terriers is eating food that is made just for puppies from a reputable brand.

Foods We Recommend for Rat Terriers Adults
When should Rat Terriers start transitioning to adult food?
When they're 10 to 12 months old
From a nutrition standpoint, Rat Terriers become adults once they reach about 90% of their expected weight. Once adults, our two key nutrition goals are balance and maintenance. We want balance because a dog’s body is responsible for a lot of things, like digestion, fighting infection, keeping muscles strong, and chasing squirrels. These are all important tasks, so we want to make sure each body function gets its share of nutrients. We also need to maintain a healthy weight. Underfed dogs are at risk for malnourishment, and overfed dogs can become obese — both of which lead to even worse problems for a Rat Terrier

Foods We Recommend for Rat Terriers Seniors
When should Rat Terriers start transitioning to senior food?
All dogs can age differently, but small dogs like Rat Terriers can start to benefit from senior food around 8 to 10 years old
Ever watch kids running around the playground and wish you had that energy again? Yeah. Dogs get there, too. The metabolic processes in senior Rat Terriers slow down as they age, which often means they aren’t needing quite as many calories as they did in their prime. Smart dog food companies have formulated senior diets to ease up on calories but still help them feel full and give them adequate maintenance protein. Still, like humans, everybody is different. Sometimes older dogs need just as many calories, or more, depending on how their bodies progress. So keep a close eye on their body condition, and look for dog foods made for seniors.
