I've decided that, as an early new year's resolution, I would walk my dogs by myself more often (normally, it's my brother that does it). And I was wondering: Is there anything that I can use to listen to my Ipod safely? Keep in mind that I have two 100+ lb. golden retrievers, so I'd have to be REALLY careful, if it's possible at all. I just wanted to see if you had any suggestions. Thanks in advance!
