If your dog is pulling extremly on the leash, it means pure stress for you and your dog. This leads to frustration on each side which will hinder successful and positive training efforts and results. Pain in the shoulders, dangerous slipping situations, stress for the dog through painful dog harness constrictions – leash pulling behavior and ‘leash-rambo’ are familiar terms. A tool suitable for dog-training in accordance with the animal protection laws, now offers support.

  • stressfree training

  • robust
  • best materials
  • Immediate Results


The traindee® leash-expander is a professional accessory for dog training.
The shock absrober for dog leashes offers a unique, 4-times extension from 1m up to 4m when fully stretched.
Do not use the traindee® leash-expander for ordinary walks with your dog or in daily life as a leash replacement!
Due to the functional principle of the traindee® leash-expander, your dog has the possibility to move away
a much longer distance from you than it corresponds to the length in the untensioned state!
Always consider using and locking the provided carabiner with closing mechanism for additional safety (depending on
your dogs behaviour and harness type)

Standard Edition black, approx. 100cm, for all dog breeds

The 100cm standard leash-expander is suitable for a wide range of dogs weighing approximately 25kg.
In contrast to the 50cm standard leash-expander, a better training success is given to very strong and reactive dogs,
where the 50cm versions quickly reach the maximum expansion potential.

  • For strong and reactive, as well as heavy dogs
  • For a body weight of about 20 – 40kg
  • Resistance at maximum elongation about 22kg

Perfect Product for dogs that pull on the leash, even if your shipping costs to Luxembourg are crazy….

Rated 4 out of 5


Rubber looks ugly after short time of heavy usage. Carabiners too small but easily changeable. But very good and robust and really professional shock absorber for dog leashes! The 4-times extensibility is really unique. Shipping too expensive.

Works for my leash jerking monster but you need to practice the handling of the traindee. Too expensive in my opinion.

Articolo come da descrizione, perfetto per chi possiede un cane taglia media (20kg>) e vuole iniziare ad addestrarlo per una passeggiata piacevole senza strattoni improvvisi. Sconsiglio l’utilizzo in sostituzione del guinzaglio normale , decisamente funzionale in condizioni di pieno controllo (parchi, aree libere) dove è possibile iniziare ad educare il cane a non tirare senza troppe distrazioni.

Should only be used by experienced dog owners or dog trainers if your dog is pulling heavy on the leash. Good concept and versatile application possible.

ethan the dog

A really good training concept and aid for dogs pulling on the leash Handling is not so easy and has to be practiced because a strong dog can stretch this traindee to 4m easily!

Rated 5 out of 5
