Individual adjustment to the dog size

We adapt each BioThane leash to the dog size according to your selection. At SammyLunaDesigns we take into account the leash width and the size of the built-in carabiner on the dog side.

Depending on the line width selection, different carabiner strengths are used.

If you have any special requests , please contact us via chat .

Width carbine Guideline dog
Narrow (13mm) Small Minis up to 8kg
Universal (16mm) Medium 9-25kg+
Wider (19mm) Large From 25kg
The weight information is only to be understood as a guideline and as our recommendation. These are not “hard borders”. The 19mm wide version is also recommended for dogs that pull very hard and for those who would like to have a little more material in their hands.

Which leash length do I need?

You have the option to choose from different lengths . The recommended leash length also depends somewhat on your dog's personality and how he walks on the leash. Young dogs tend to use “too much leash” to their advantage, which you can prevent with a slightly shorter leash.

You can find out more about the usage recommendations in the product gallery.

Can be used as:

City leash / short leash (140cm)
Lead in standard lengths (200-240cm)
Shoulder leash (from 240cm, more like 260-300cm)

General information
- Correct leash attachment

The end of the leash with the ring integrated immediately after the carabiner belongs on the dog side.

- metal goods

Screws, carabiners, rings and buckles are exposed to constant friction. This is a natural process and can hardly be prevented with dog leashes. Our “hardware” is pre-treated differently depending on the color and therefore has different abrasion resistance. Basically, we use metal alloys of very good industrial quality, which have a very high corrosion resistance. (Very robust against rust formation). Every hardware used is checked and tested before use. You can find the specific hardware used in this product listed above.

  • Painted hardware (black): Most vulnerable, the paintwork can rub off over time.
  • Copper-plated hardware (rose gold): Low susceptibility.
  • Brass plated hardware (golden look): Low vulnerability.
  • Real brass hardware (gold): No vulnerability
  • Silver Hardware: No vulnerability

Color deviations in the display are possible and depend on the calibration of your display. We try to represent the colors as realistically as possible and so far we have only received positive feedback.

A dog leash is part of the basic equipment and is used daily. Therefore, signs of wear and tear are a completely normal occurrence in the long term.

With proper care & use, SammyLunaDesigns linens will last for several years.


You can simply run the material under water or wipe it with a damp cloth. Avoid using strong, aggressive cleaning products. If it is very dirty, you can help with a little neutral soap or liquid detergent.


Wipe dry roughly with a lint-free cloth and then let it air dry. Avoid heating, hairdryers and dryers.

Carabiner care

Greasing: We recommend regular oiling at intervals of approx. 6 months or after intensive washing processes. If you spend most of your time near salt water, this recommendation is reduced to shorter distances depending on your needs and local conditions.

Cleaning: After spending time on sandy beaches, for example, check that the carabiner is properly closed.

In general: The classic bolt carabiners are known for blocking themselves with grains of sand. The scissor carabiners, however, less so. If necessary, simply clean the carabiner under running water.

Product-specific questions
  • How safe is this dog leash?

This dog leash from SammyLunaDesigns is 100% safescrewed.Our screws all come with an additional onehigh-quality screw locking adhesivefrom a well-known manufacturer. Loosening the screw on your own is therefore almost impossible.

  • I'm concerned that the carabiner is too weak.

You can find the maximum breaking loads of our carabiners described in the product gallery. These are breaking load values ​​tested in the laboratory. In practice, however, the tensile forces are distributed somewhat differently. Part of this is mitigated by the dog's fur alone, another large part is distributed between the harness/collar and the materials of the collar and leash. Therefore, the breaking loads are generally even higher than those stated. The tensile forces rarely act 100% directly on the carabiner.

  • What are the breaking loads of the carabiners?

Line width 13mm: 100kg (in practice a little higher)

Line width 16mm: 200kg (in practice a little higher)

Line width 19mm: 230kg (slightly higher in practice)

General information about dog leashes
  • How long do you need to make my leash?

Since we make all of the linen ourselves by hand and the selection of colors available is enormous, we often have to order the desired color from the supplier first. If we already have the materials in stock, it usually takes between 1-3 working days, otherwise as stated under "Delivery times", until your leash leaves our factory.

  • I would like to exchange one color for another

Write to us via WhatsApp or email with your change request. Since we manufacture to order, the desired change should not be a problem.

We also offer configurators, where you can configure your leash 100% yourself.

To the configurator

  • What leash length do I need for my dog?

This depends on your training goal or your personal taste and the use of the leash. If you are very motivated and often train with your dog on a leash, then we recommend a maximum leash length of 200cm. If you want to hang the leash around your neck, we recommend a length between 240cm - 300cm depending on your body type. For dogs that pull heavily on the leash, we recommend 180cm-200cm.


The lengths are always given when the leash is open. Measured from carabiner to carabiner.

The lengths of retriever leashes are always to be understood without the neck of the leash. The space required for the head/neck loop is then added.


Please use our measuring instructions and do not base your measurements on sizes from other manufacturers or collars.

For measuring instructions

Avoid these mistakes

  1. Dog was lying there
  2. It was not measured closely
  3. Measure your own on an existing collar
  4. Estimates & inaccurate readings
  5. The majority tends to measure too generously

Measure correctly

Measure neck circumference

  1. Get the dog to “stand” or “sit”.
  2. Place a flexible tape measure at the collar point
    (alternatively: cord/thread/shoelaces)
  3. Pull the tape measure tightly
    Note: Do not use the famous “two-finger buffer rule.” Make sure you measure snugly.
  4. Read the value (or measure the length if using a cord). We recommend carrying out another test measurement.
  5. Note the note below about adding a “feel-good buffer.”
With a tight rope collar
💡 Please do not add a buffer . We automatically manufacture your rope collar with a 2cm buffer. So just enter your measurement result.

With any other adjustable collar
You can add another 1-2cm buffer and then determine the size you need and select accordingly in the product.

If your size overlaps with another size (e.g. M and L), we recommend choosing the larger one. It is also possible to make an intermediate size. To do this, select the “larger” one in the product and write your desired intermediate size in the note field in the shopping cart.

Measure head circumference

  1. Get the dog to “stand” or “sit”.
  2. Place a flexible measuring tape around the widest part of the head - often directly in front of the beginning of the ears
    (alternatively: rope/cord/thread/shoelace)
  3. Tape measure tight pull
  4. Read/mark value, carry out test measurement if necessary - round up decimal values

💡 If you use a tape measure alternative such as string, thread, shoelaces, you can then measure the marked length on the string with a ruler.
