Stewie is a Scottish terrier who lives with his dad Ian in the beautiful state of California, USA. As a pup, Stewie was so freakishly clever that Ian started reading up about animal intelligence and his curiosity led him to try teaching Stewie math games. The handsome Scottie dog is now five years old and able to count the pennies that Ian lays out, as well as answer addition and subtraction problems.

Can You Handle the Cuteness? Stewie Counts Coins

In the first video, we can see Stewie counting pennies. Ian arranges the pennies where Stewie can see them and then the clever doggo selects a number shape as his answer. We see Stewie wagging his tail and chewing victoriously on the game piece before spitting it out so that Ian can set up the next math question. The number shapes are all chewed-up and well-used, a testament to how many times Stewie has chewed on the pieces with joy because he’s answered his math question correctly and received praise and a treat from his main man, Ian.

Did you notice how Ian rewards Stewie with both a dog treat and a lot of verbal praise? This is a psychological training method called positive reinforcement, and it works on humans too, not just pets. The idea is not to punish failure, but to reward success, and it works to train both pets and children to behave well. (So if you’re a parent or a pet owner and you want to train your kiddo or your doggo; you can read more about this method on Wikipedia or on Psychology Today. But it probably won’t work on cats.)

I asked Ian for some photos of Stewie playing his math games but it turns out that like most math geniuses, Stewie can sometimes be adorably camera-shy, so if he looks a bit abashed in the photos below, it’s because he’s very modest about being both ridiculously clever and ridiculously good-looking.

Camera-shy math genius Stewie prefers to do addition and subtraction instead of posing for the camera.

This Canine Calculator can Add and Subract too!

Stewie is so smart that Ian was able to teach him how to add and subtract too, by paying Stewie for his brain work with a treat while asking the question. What’s most impressive about this video is that Ian isn’t using visual stimulus in the form of physical shapes, like in the penny counting game. He’s asking the questions verbally, which means that Stewie has made the connection between the shape of each number and its spoken name. Stewie isn’t just playing a matching game where he sees a specific collection of shapes and then chooses the corresponding number shape that will get him a treat. He is doing actual math, which requires him to understand the concepts of addition and subtraction.

Because Stewie is unable to write out his math questions, he has to compute his answers in his head. Adding and subtracting without writing down the equation is something that many human beings struggle to do. This makes the Scottish terrier’s math skills all the more impressive.

Handsome Stewie the math dog is a Scottish terrier who can count and do addition and subtraction. He doesn’t use the number shapes shown in the photo to do his maths – this Scottie does all his math in his head.

It’s a Dog’s Life

When he isn’t playing math games with dad Ian, Stewie takes his human for walks in the park and playtime on the beach. Stewie enjoys barking at coyotes, howling, “Aroo!” to announce his presence at the beach, chasing squirrels and sunbathing. And he’s quite the social butterfly online. He has his own Instagram account and Youtube channel. Follow Stewie and Ian to see what new awesomeness these two will come up with next.

When he’s not playing math games with his dad Ian, Stewie the math dog likes to hang out on the beach in sunny California.

Stewie the math dog also likes to chase squirrels in his spare time.

Stewie is a super clever Scottish Terrier who likes to do math, play on the beach and sit among the flowers in Californian gardens. (He’s single, ladies!)

Like all Scotties, Stewie the math dog enjoys a spot of sunshine for some introspection and relaxation.
