Patches the Dachshund had 70 percent of her skull removed, but you’d never know it by looking at her.

Four years ago, Patches had a bump on top of her head. Her owner, Danielle Dymeck kept an eye on it as it continued to grow. Turns out it was a life-threatening tumor. It was pressing on her brain and needed to be removed.

So Dr. Michelle Oblak, a veterinary surgical oncologist at the University of Guelph’s Ontario Veterinary College and a team from Cornell University made her a replacement skull. Using a 3-D printer, they made a new one out of titanium.

The first of its kind in the U.S., the implant fits perfectly over her skull.

Way to go, Patches! Have a great weekend!
