A video recently posted on Instagram shows a pit bull running up to a bison in Yellowstone National Park. It didn't end well for the dog. Don't worry, it survived.
Trying to get closer to bison is dangerous for many reasons. It's obvious these are large animals, but they're also wildly unpredictable. Yellowstone tourists learned this lesson the hard way a few weeks ago.
In my mind, this falls under the category of things you don't have to tell me once, let alone twice. The National Park Service's suggestion: Don't pet the bison.
