Woof woof ....... woof woof woof. I wish I had a dog. I dog-sat for a really fun blue healer a few months ago. This dog would avidly chase a flashlight light circle and shadows- I mean until she was in a lathered sweat if I didn't put it up. Unfortunately for me, that same fervor was why she tore a hole through the cheap shed door to get in the shed after something she heard in there.
