If the work doggy was mine, I would spend the time to wean the dog off the light chasing. I have watched a LOT of Ceaser Milan and think that his approach to unwanted behavior is rather well structured and easy to perform. The only difficult part is the dedication. You have to be a responsible dog owner and be conscience of your dog's behavior. If it just starts to fixate on the light, then you gotta snap the dog out of it. It has to be reinforced over and over and in multiple situations. But I think eventually the dog will learn.
I didnt have the time to do this with the work doggy. But I was able to teach the dog to respect my space and food. Whenever my boss or co-workers get food at the microwave or fridge and eats food at work the dog hovers and begs for food.
I do not stand for that. I always have the dog sit far away from my personal space when im getting food or eating it. Only when i feel like it, do I invite the dog over to have a scrap of food. Just like how a pack leader should.
The dog picked this up pretty quickly.
My boss and co-workers were surprised that I could get the dog to listen to me. It is pretty simple. Dont have a conversation with the dog. Dont treat the dog as a person. It is a dog. Short simple sounds, like Ceaser Milan, projection of your energy and the dog will pick up on it. however this only applies when disciplining unwanted behavior. you can love and talk to your dog all you want. But if the dog is doing something you dont agree with or you want to stop, then you have to treat the dog as a dog. You are the pack leader. Simple as that. The dog MUST obey and follow you.
