traindee® – the flexible dog leash when your dog is pulling

traindee stretchable leash for dogs pullingYour dog is pulling on the leash?

This 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 jerking are familiar terms.

A tool suitable for dog-training in accordance with the animal protection laws, now offers support.

  • 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.

Marilyne F.

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!


Perfect for leash jerking dogs. Shipping is too expensive.


Does not work as expected

old school dog training

not good. use proven techniques. nice idea.


Good solution if your dog is pulling on the leash. Expensive shipping.


Efficace pour le chien et un soulagement pour le maître


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!

I use it for Tec-Diving and Kite-Surfing 🤩

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 for leash pulling dogs. Delivery in time!


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.

real dog trainer

does not stop leash pulling as expected. returned.

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.


très bon concept pour les chiens tirant en laisse


That’s what I have been searching for. Perfect tool for dog training and leash pulling behaviour correction.

dressage des chiens

la meilleure laisse élastique de chien ! les chiens arrêtent de tirer sur la laisse !


ottimo guinzaglio per cani. enorme capacità di allungamento. perfetto per cani stressati. smette di tirare il guinzaglio in pochi minuti. spedizione costosa!

pro dog

good leash for stressed and pulling dogs. very elastic and robust. not comparable with other shock absorbers. (the traindee really stretches 4 times)

dog trainer

Absolutely the best leash for reactive dogs! Often it’s hard to get out if your dog pulls on the leash for a long time. With this shock absorber there is a new way for modern behaviour correction.


Good dog leash.


Pour les chiens qui tirent fortement, cette laisse élastique et extrêmement extensible est parfaitement adaptée !

dog fun



Bonne solution pour les équipes humaines-chien qui sont stressées par la traction en laisse. Également bien applicable en thérapie, mais recommande quand même une formation par un dresseur de chiens !


Il nostro cane è un esemplare unico con molta forza. Ci ha tirato e derubato dei nostri nervi. Super soluzione se il cane tira e nient’altro vuole aiutare!


I don’t like this leash. It’s to big and carabiners are impractical. Good quality anyway.


Perfect training aid for leash pulling dogs. The traindee really helps because it slows down your dog the gentle way.

Roger M.

Really fantastic how this dog leash can stretch by 4 times! This is unique and really helpful to slow down leash pulling dogs without any stress. Perfect for hiking and dog training.

dog product tester

quite good dog equipment. kind of needed accessory. it’s ok


bonne laisse de chien contre la traction

Golden retrievers

Je peux encore m’en servir pour sortir avec ma Rotti malgré mon tennis elbow. C’est mon médecin qui me l’a recommandé ? Pourquoi les très bons produits ne sont jamais disponibles en magasin ?

comfort dogs

Perfect leash for pulling dogs!


Při běžných procházkách shledáváme vodítko příliš nevhodné, protože náš pes rád chodí na jiné psy a my jsme tam spíše ohromeni. Společně a po konzultaci s dalšími majiteli psů je však velká pomoc při setkáních bez stresu u lidí.


E ‘davvero affascinante che tipo di scarto si ottiene nei negozi e allo stesso tempo da qualche addestratore di cani è ancora scopata da alcuni hauptsache si blecht regolarmente. Ben di [Link rimosso] ci ha davvero aiutato a tenere sotto controllo il problema con la nostra stronza. Con questo guinzaglio ha smorzato i nostri nervi e potremmo lavorare di nuovo in pace con Penny sulle sue “aree problematiche”. Ora non tira quasi più, anche senza l’ammortizzatore e soprattutto senza doverla ricompensare costantemente con il cibo. Semplicemente TOP! 👍 👍 👍


Na zwykłych spacerach uważamy, że smycz nie jest tak dobrze dopasowana, ponieważ nasz pies lubi chodzić na inne psy i jesteśmy tam bardziej przytłoczeni. Jednak razem i w porozumieniu z innymi właścicielami psów, ogromna pomoc, aby spotkania były bezstresowe dla ludzi.


For me as a protective leash in a tendonitis in use ….
