Animals are way more intuned than we are. Everytime there's going to be a thunder storm my horses and dogs all act weird. The dogs want in the house and the horses run around and kick and buck and snort. I read an article about the tusnami in Thailand about how there were hardly any animal deaths because they had all fucked off ( if they could )just prior to the event and headed for higher ground. It was very interesting. They pick up the vibrations we can not feel. Pay attention to your dog. He or she will always alert you to danger.
