Wolves Howling video

This is a video of the wolves howling, I tried to upload it before, but it was taking to long so I gave up.... it's takes a very long time to upload stuff like this it's a very annoying wait. You might notice a bell in the background of the video, it's something that we have to wear while giving out "meatballs" it's so the wolves learn to come up to the fence, so we can give them medicine if they ever need it...
