Then the dog needs to wait to walk till your ready to walk. Now this may take several attempts till the dog understands, then many more while your walking to keep the dog beside you and not in front of you. It’s important to correct patiently and calmly. Any frustration will be picked up by the dog and he could become sensitive or more unruly. Just remember ‘slip leads’ give you more control over the head and neck more than any other leash, which makes them ideal for dogs that want to lead you instead of the other way around, or aggressive dogs. You can definatly use a harness for safety when hiking, or to have more control over a very large dog like a pit, but it is more important to have control over the head so you need both in those instances. Just remember loose leash. A dog learns nothing from a tight leash except to pull more!
