Getting ready for puppy Juno. Some of you are using a harness vs collar for teaching leash walking. Never done that. I am not planning on a harness once good on walking with me. Just want to know if there are any benefits for the first several months. I think a harness can be beneficial for learning to be tied up and swimming. Do you use a regular, nylon web harness vs the padded ones? She will wear a collar for the ID tags.
