TIP #1: PROPER WALKING ETIQUETTE
Teach your dog the difference between walking and heeling. Whether you're teaching "Heel," or the less formal "Let's walk," the correct position for the part of the leash that stretches from you to the dog is slack, hanging down in a valley.

TIP #2: DON'T LOSE YOUR MIND OVER TRAINING REGRESSIONS

It is so important to remember that behavior is always in flux, constantly subjected to whatever contingencies there are in the environment as well as being influenced by unknown internal events. Stay calm and train.
