Nikko definitely likes to pull on his harness during walks and i found that he hated the step in harness. He would squirm and give me a hard time putting it on. I bought him a puppia harness and he loves it!! It is super comfortable, easy to put on and they come in lots of colors. I paid about $20 for it in a pet store around my job but you can get them online. It was worth every penny and I recommend it.
