If your dog See's a spirit or demon, calm down, count to ten. Dogs see things their not suppose to see. But if that happens, it might mean bad luck, karma, or something incredibly AWESOME. But beware of what you believe.
When you know your dog is going to get exited have her sit. Dogs can't go when sitting.
Probably because it sees something like a cat or a chipmunk it can chase. But I don't know. I'm just guessing
Maybe they sense that something is wrong when a dog sees you are afraid of them they know not to be afraid of you but if something is wrong they might want to give you some space.

Messages travel from the dog's eyes to their brain.
no worries, it probably is just because the dog sees food that he or she really wants.
Salivating when it sees food
Your dog stretching when he sees you can be a sign of anticipation or excitement. It may be a way for your dog to prepare for interaction with you or to release pent-up energy. It could also be a way for your dog to show you that he is comfortable and relaxed in your presence.
You're dog probably hears the noice and sees the movement and finds them interesing
You make sure the dog doesn't see a cat and if it does you keep them away from each other.
most of the time when you shoot a red laser on the ground. when the dog sees it, it goes charging at it. and when you put it on the wall (make sure it sees it) if it's low enough it will jump for it. when it is up high, it will bark at it.
