Dog Tells on Other Dog
There was a comic by the name of Brother Dave Gardner that had a bit about why men love dogs. The bottom line was that mean like dogs so much because they won't tell on us. There's a lot of truth in that statement. My dogs has never even come close to ratting me out about anything.
In this video you'll see that, while dogs may not tell on their masters, they just might rat out a fellow dog. It seems that one of the two dogs in the video got into trouble for playing with a toilet paper roll. I can identify, because that is one of my dog, Hank's, favorite things to do.
At any rate, watch this video while one dog actually points to the other one when he/she is asked, "Who made this mess?'
