Fade, that reminds me of the other night. My neighbor's dog is barking and screaming like it is being mauled. I hop out of bed, put on a pair of gym shorts, drop a pistol in my pocket, and head to the door. I get in my living room, and my dog is acting like he has not heard a thing (he's 10 & 1/2, so he may be going deaf.) I open the door, my dog goes out first then proceeds to sit in the middle of the front yard like nothing is happening.
Just as I realize it is too fooking dark, and I'd never be able to see a wolf/cougar/feral dog in these conditions... I decide to head back in the house. I tell my dog to go back inside... Then the dog that I was worried about started barking at me.
That had to be the first time I've ever heard a dog scream as part of a nuisance bark.
