Quick question for those who have dogs with soft feet: How do you keep them from falling apart? Zero's energy is through the roof since he can't go off leash anymore and is pretty much uncontrollable when he tries to let loose. I've been walking him and attempting running, but I'm not able to run as long as he needs and when I try it doesn't seem to help. He runs beautifully with bikes, but he doesn't pick up his feet or his pads are too soft or something because the pavement rips his feet to shreds. Are dog shoes appropriate for running? I imagine they'd be uncomfortable, but I have no idea. How do you condition a dog's foot for abrasive surfaces?
