On Saturday, August 17th KUTV 2News came across a video of an unlikely friendship between a dog and a bison.

It looks like these two met in Gillette, Wyo. We always warn tourists to not play or touch the bison, now it looks like we need to teach our dogs not to play with them either. Even though these two seemed to be having a great time playing chase with one and other.

At first, it looks like the bison is chasing the dog back and forth along the fence, the dog doesn't seem to be scared of the bison either. It almost appears at first maybe the dog is protecting his yard but having fun at the same time. Then a second bison comes up and doesn't seem to want to play and maybe tries scaring the dog off, this is all speculation. Watch the video and tell us what you think, are they playing or not?
