I'm having troubles walking one of my dogs right now. He's young and a rescue and tugs on the leash more than he should. We're working on that, but in the meantime, a dog walk leaves me in pain because I'm going through a flare up of fibromyalgia. Can any of you recommend a leash or gadget or strategy for walking on the leash with less yanking on my body? Unfortunately I haven't yet found a safe place for him to run off-leash. Corky has shown aggression to bad-mannered dogs.
