Should I listen to music while I walk my dog?

Would it be weird or abnormal to listen on my iPod while walking the dog? Do I have to make sure my dog hears commands and that I hear me giving it to him? I don’t care what other people think if they see me with headphones on walking the dog, I only care about what I just said. I love listening to music wherever I go and when I go jogging or walking around the city looking for things to do I’m always listening to music. But would this be the wrong time?
