Wild One Harness is great for puppies. It's comfortable for lively playtime and impromptu naptime. We do recommend sizing up, as pups can outgrow their walk gear as they get older and grow into their adult body.
Yes! Wild One Harness has three leash-attachment points, 1 in the front and 2 in the back, because we all lead in different ways. The front attachment is useful for reducing pulling while on walks.
This all depends on your dog's walk style. The front attachment is best for dogs who pull, as it can minimize their freedom to charge ahead. The back clip is slightly more versatile, and recommended for dogs who are trained to walk with their pet parent.
