The length depends on what you and your doggo are doing and the size and temperament of your dog. If you are just using the lead for walking your furry friend, lengths of 1.2 metres to 2 meters tend to be most common. Most little dogs like longer leads while larger dogs feel more comfortable on short dog leads. You might opt for a longer lead to allow your doggo to explore all those wonderful smells a bit more, and it also gives them an opportunity to get off the sidewalk if they have to use the bathroom. Dog training leads can be anywhere from 4.5 metres to 9 metres in length. This gives the dog a little more separation from you as you are teaching them various commands. If you choose a longer lead, you can shorten it if needed simply by wrapping it around your hand a couple of times.
