Is there any secret(s) to teaching a dog to heel on both sides? I have always trained my dogs to heel on my left. I thought it would be a good idea to have this puppy learn to do it on both sides. I started him out on my left and now I just alternate each side when I am training him or just out for a walk. He is a little confused when I want him on my right. Should I just keep doing this and let him figure it out through reps? He will be 5 months old next week.
