The line is the part that will join you and the dog together. There is different lines on the market. The line has to have a bungee/shock absorber for when the dog accelerate or if you slow down or stop sudddenly. 

This product is from Non-Stop dogwear, the whole line is stretchy

This product is from Winterson Sports, the bungee is protected in the nylon pocket

This product is from Zero DC the bungee is protected in the tubular webbing

Here are the different part of a line

Snaps, bungee and the line

The different product available

The leash bungee type line (usually for canicross, cani-walk, dog trekking)

The single bungee line (bikejoring, dog scootering, skijoring, kicksledding)

The double bungee line(bikejoring, dog scootering, skijoring, kicksledding)

The line with a lighter bungee for smaller dogs (canicross, cani-walk, dog trekking)

The line with a heavier gage bungee for larger dogs

What is the length of your line when stretch and unstretch? You are planning on participating in an official race, you should know that because there are different rules about the length of your lines in the sport that you are going to compete in (rules and regulations of the different organizations)

What product is used in a line?

Some are made of poly tubular webbing. Other can be made of polypropylene or polyethylene rope.  Polyethylene is better for joring sport, it resist to mildew, is more expensive  does not retain water. Polypropylene is cheaper, is light weight but not that resistant to UV light compare to other type of rope. So, that is why you should always protect your gear from sunlight. Don’t let them stand in the direct sunlight for an extended period of time.

After when we talk about a rope we use the term strand. Usually a mushing/ joring line has 16 strands and is between 8mm or 10 mm. The rope most commonly use is hollow braided. A hollow rope remain flexible in extremely cold weather and can stretch.

Synthetic line should be cleaned with warm water and detergent, don’t let your line in the sun, stored them in a cool dry place and inspect them frequently.

When we talk about line we also have to talk about the way the part of a rope hold together. Musher use specific way to have the rope hold together they call it rope splicing. Here is the definition from wikipedia:

Rope splicing in ropework is the forming of a semi-permanent joint between two ropes or two parts of the same rope by partly untwisting and then interweaving their strands. Splices can be used to form a stopper at the end of a line, to form a loop or an eye in a rope, or for joining two ropes together.

Here is something interesting from this site:

''Certain colors offer better ultraviolet protection too. I am sure that most people are familiar with the fact that organic dyes and pigments fade. Red is probably the worst offender, followed by yellow. Bright white and black generally hold up the best. In polypropylene rope, the black will generally do better than the white. Since the polypropylene is naturally translucent, it takes little white pigment (usually titanium dioxide) to make it white. Black is cheaply obtained by adding carbon black to the polymer melt. The white pigment tends to reflect the ultraviolet while the carbon black tends to absorb it and convert it to heat. With its low pigment loading, black polypropylene is probably better than the white.’’

Also manufacturers will use snaps or/and a carabiners. There are different sizes and quality in those products. In the snaps the best quality will be italian bronze. For the carabiner make sure it is the right size, the pulling force of your dog could brake it. Aluminum will often not be strong enough.

Other important part of your line. The bunge/elastic. Different manufacturers will use different type of elastic as a bungee. Some will use rubber strap who are very ofter too stiff for one dog to stretch or bungee cord could also be use. To be effective the bungee has to be somewhat easy to stretch by the dog. Not too stiff and not too flimsy.

What is the size of the dog that is going to pull on the line? This is important. If you are planning on doing canicross with your dog. And this one is a chihuahua make sure that the line that you are going to buy is a bungee suitable for a chihuahua. If the bungee is too stiff the dog will not be able to stretch it so main as well to use a simple line with no bungee.

Important point as I see a lot of people wearing the line the wrong way. The bungee part should be closer to the human unless you have two dogs line, some line will have a bungee for each dogs. In this case the bungees will be closer to the dogs since the line is in a ‘ Y'’ shape.

Important!! For the human and for the dog. The human should be seen by a doctor prior starting an exercise program, ask him if the program will be appropriate for you. Same thing with your dog. You should see the vet about the new exercise program that you will be starting with your dog to know if it will be appropriate.
