*Important note: There may be differences in build within the same breed. The breed recommendation is for guidance only and is not a guarantee. To determine the right size, we always recommend measuring the chest circumference.
Our leads are available in two different sizes. The standard size has a width of 2 cm and is recommended for collar sizes S-XXL. The small version is thinner (only 1.5 cm instead of 2 cm) and has much lighter fittings. The small lead is therefore specially adapted to the needs of small dogs for both weight and visual reasons. We recommend it for collar sizes XXS and XS.
The 3-way adjustable lead has two carabiners, two D-rings and an O-ring so that the lead can be adjusted to three different lengths. It can therefore be used flexibly and is the right choice for everyday use.
Our city leash has a fixed length of 1.5 m and a fixed hand loop. It is approx. 90 g lighter than the 3-way adjustable version and the right choice for city walks with a tight lead.

In this way, you can ensure that your dog receives the collar that fits perfectly and you avoid the additional expense of a possible exchange.

Why you and your four-legged friend will love the Pico harness
We analyzed over 100,000 product reviews, surveyed over 20,000 customers, and conducted 50 long-term tests. In doing so, we identified and, of course, solved the following problems:
Perfectly matched for
5 coordinated sizes with specially adapted, lightweight fittings. Designed for small dogs and for an optimal fit and maximum comfort, even for dogs with unusual body shapes such as dachshunds or French bulldogs.


Painful chafing, sharp edges, and no padding? Not with William Walker harnesses.

Fine nappa leather
Full-grain nappa leather with elaborately folded edges. This prevents sharp and rough edges, which can not only be very uncomfortable for your four-legged friend but can also cause inflammation and skin irritation.
Tear-resistant nylon insert
To increase tensile strength and prevent the stretching that is common with most other harnesses, a hidden nylon insert is incorporated into the inside. This ensures that your harness retains its size even after prolonged use.
Super soft padding
For maximum comfort, the inside of the chest pad is thickly padded. This makes the harness pleasantly soft for your four-legged friend, even when pulling.
