A couple posted a video of their two bulldogs getting out of their house and running up to a black bear.  It's amazing how this bear reacts to two much smaller animals challenging it.  The video will change your mind on how fearless bulldogs are.

Then you have a group of video production people on a boat shooting footage for their show, "MaxAnimal."  

They were off the coast in South Africa when a great white shark decided to attack their boat.  

They were pretty calm considering an apex predator was eating their inflatable boat!

No one was hurt during this incident.  The film crew noted that great white sharks are "amazing creatures" that should be respected and protected.
