Pete Thorne is bored with cute puppy pictures.

The Canadian photographer resolved his distaste by snapping a series of senior dogs who are just as cute as puppies in their own disheveled, snaggle-toothed way.

Thorne started small with the project, photographing a friend's greying dog named Sprout against a solid backdrop. When he felt confident enough, he put up a few posters advertising the project and asking for subjects to spotlight. He was shocked by the overwhelming response he got from the public.

The project, titled "Old Faithful," has now expanded to include 50 photographs of old dogs. Thorne regularly updates his collection on Instagram and Facebook.

The size of the collection isn't the only thing that's evolved over the duration of the project.

Thorne told Mashable that his vision behind it did, too.

"I thought I would simply photograph some old dogs, choose the ones that look like caricatures of old guys and gals, and that would be it. It wasn’t until I started hearing about dogs that I had photographed passing away and having their owners notify me, telling me about their loss, that I realized just how significant and close people become with their pets."

Thorne now sees the testimonial accompanying the image as an equally important part of the project, and encourages the participants to submit info to help bring the dog's story to life.
