Poodle dog runs off possible Bigfoot

While I was visiting the Eagles nest today I could hear footsteps coming up the steep hill behind me. If you listen closely on the first of the video you can actually hear white sounds like two big feet walking towards me. Zack laid there with a low growl coming out of his throat until he just couldn’t stand it any longer and had to go stand up to whatever it was. Could it have been a BIGFOOT? I don’t know for sure.
