 Yeah, it does hold merit because, you know, a dog's nose is the equivalent of your eyes and my eyes. So when you come here smelling like a dog down the block, probably a dog he's heard before, a dog he knows the bark of before. So you're absolutely right. They can pick up the scent of another dog, and that may make them a little aggressive or assertive with you as well. So what you can do as a postal worker, what you can do is you can say to the people, listen, I want to give your dog a treat or I want to get to know your dog, but I can't let him jump all over me because I don't want to get his scent on me.
