So I usually wear a bum bag when I walk ddog, to carry her treats, poo bags, and my phone. However I would love something that I could also put my coffee cup in. I like to have my hands free to deal with her, she’s off lead most of the time but sometimes I need to grab her and out her lead. Also it’s hard to hold a coffee and pick up the poo! Am I asking for the impossible or does anyone have something I don’t know about?
