I have a 3 year old dog who picks it up. I will be doing something and the next thing i know im somewhere else and he is barking at me. He barks any time i feel like a "switch" may be happening. He saved our lives literally once. I was watching tv wide awake and the next thing i know he is barking at me and im in the other room. His bark is what snapped me out of it and i heard the fire alarm going off, over an hour had passed. I guess someone got hungry and wanted spaghetti o's and started cooking but never turned the stove off or anything, all of the spaghetti os were black, the whole hour full of smoke, burner was on high. I dont understand that one yet, if they could start cooking it i dont know why they wouldnt respond to the fire alarm or anything... but the dog, any time lets say i find myself in the kitchen looking in the cabinets and dont know why or how im there, hes almost always there barking and growling. Animals have a sixth sense
