Getting your own DNA tested is so last year.

Now you can get a peek inside the genetic makeup of your dog. The method gives a rough estimate (it’s not a perfect science), but it offers some intriguing insight for people who may have no idea what breed their best friend comes from.

The purpose of a dog DNA test is “to identify the breed or breed composite, which can be quite helpful information,” Urs Giger, a veterinary clinician and researcher at the University of Pennsylvania’s School of Veterinary Medicine, told Discover.

In other words, you can learn a lot with a dog DNA test — but like any other DNA test, there are some limits to the accuracy of the results.

I gave it a shot with my family dog, a mixed-breed rescue pooch named Izzie who we adopted from a Golden Retriever shelter in Los Angeles when I was a kid. Here’s what I learned.

But Izzie stayed roughly the same size, and we stayed curious about her heritage. Now 15 years old, she’s friendly and loyal.
