On the topic of walking.....today when walking the neighbor's puppy, she was super energetic, running around, sniffing, etc. I let her chase leaves, but that was the only time that I would speed up for her. I thought that letting her pull me along could develop a bad habit, so I kept walking at the same pace the whole time, and let her move freely around me on the leash (aside from when a car came pass, so I made sure she was on the grass). I realize now that that was putting a lot of pressure on her neck. Being mindful that this isn't my dog and I"m not in charge of training, what should I do? I really don't want to enforce bad habits by accident.
