I have found with my dog that the best route to go is a harness. It's less restrictive and they feel more in control; thus helping to ease them when they feel the need to pull to gain back that control. Patience is key in leash-training, no matter what dog. When I was training my girl, when she started to pull I would stop the walk altogether and make her sit, tell her no, and then proceed. I also noticed that when she was walking, and I would praise her for not pulling, she would get excited and start to pull again, so it is best to leave the praising for when you arrive at your destination and make sure to give them lots of love and treats to let them know they did good. Dogs often respond better to positive reinforcement, so stay calm, I know it can be frustrating!
