This Is Walter The Dog Who Sings Opera

I love dog videos like this one because they drive Wilcox INSANE. He never believes that they are real.  This Walter and Walter is a French Bulldog.  His bark is a lot different than other dogs and this is why he is quickly becoming internet famous.  Take a listen to this dog's barking.  It almost sounds like he is singing in an opera or something like that.  Wilcox believes this is fake and someone has replaced the audio of the dog barking...what do you say?
