 When we're talking about the paw pads, and I know this is something that I've thought about before. My dog's paw pads are kind of callous a little bit. And to me, I guess my initial thought is that that's fine for the walking on the pavement. Not that we walk on the pavement all the time, but we've got to get down over to the park. And a lot of times she's always on my left, so she's walking on the grass, usually where I like her to walk, unless it's muddy. Yeah.
