traindee® – the training-leash-expander for dog-training against unwanted leash-pulling behaviour

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
  • innovative
  • 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 0.5m up to 2m 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. 50cm, for all dog breeds

The 50cm standard leash-expander is suitable for a wide range of dogs weighing approximately 15kg.
Whether the 0.5m traindee® leash-expander is suitable for your dog depends on the combination of weight and power of your dog.
A heavy, already old dog, will have less force than a young, very active dog with less body weight.

  • For all dog breeds from about 15kg body weight
  • Can be used with all standard dog leashes and towing lines
  • Resistance at maximum elongation about 15kg

Leash pulling goodbye

Dog was pulling on the leash as hell. Very good product, solved the problem. Shipping costs to Italy are too expensive.

Shipping to France way too high, but the traindee is the perfect solution for our dog! The only way to stop the leash pulling behaviour. Thank you!

Excellent product. My dog was pulling on the leash and nothing should work. Grab a traindee when they have sales. Delivery times not very friendly otherwise 5 stars would be appropriate.

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.

Very useful when working with dogs that strongly pull on the leash!

Good dog training leash. We all know that annoying leash pulling and leash jerking. This training method with the traindee shock absorber is worth looking at it. The 4 times stretch capability is really unique. Expensive shipping 👎 but quality is top 👍

Good idea and good product. But also the traindee could not stop my dog pulling on the leash. All the dog trainers and all the different training methods did not work. The traindee is good to reduce the stress from leash pulling.

Works well when used with harness. Better than other leash pulling products. Modern way of dog training.

Good expander element compared with others. Works well because of the great stretch capability. Great help for me and our leash pulling dog. Good concept!

piece of crap. watch cesar millan if you have a dog making troubles. you have to be the leader and let your dog know that leash pulling is not acceptable. trouble dogs need strong leadership.

Perfecto para perros estresados tirando de la correa 👍

good solution for leash jerkers. not all of todays dog training methods which are considered as modern will help you with dogs pulling heavy on the leash. a good product and a very good training concept.
