If you have a dog, you're familiar with this experience. Your pup maintains steady eye contact while excreting. Why? Karen Piwinski, a dog trainer, explains that it's an instinctive behavior.
In the wild, animals are vulnerable while relieving themselves. It's the same reason why you or I might carry a bat'leth while using the toilet: we want to be safe. Your dog is stating "I trust you to keep watch." So look at this canine behavior as an expression of confidence in you.
Similarly, when your dog tries to follow you into the bathroom, consider that he's really just trying to return the favor.
