Anyone who is serious about dog training knows that the key to success is not just hard work, but also using the right training tools  and methods. That's why we're proud to present CHAMELEON® IV MEDIUM  - a revolutionary electronic training collar designed to make your training more efficient, comfortable and intuitive than ever before.

This innovative training collar of the world-famous cynologist and living legend Bart Bellon and his team represents the absolute top in the field of electronic collars. CHAMELEON® IV differs from other collars in that it was not created to punish, but to build motivation, drive and desire to work. Imagine a dog that works with great gusto and passion, always and everywhere, with all its heart and soul. With this system, it's not just a dream.

Together with CTT 4, the Chameleon® IV collar forms  a two-way communication system that allows you to maintain constant feedback with your dog. With industry-leading technology, thanks to a number of patented solutions from Martin System® , this kit takes dog training to a whole new level.


Imagine a world where training your dog every day is a struggle. Every morning, when you put on your shoes, you feel heavy on your soul, because you know that you have another difficult hour ahead of you , where your instructions will ring hollow . Your dog, despite your love and patience, seems resistant to any attempt at training or the much-anticipated improvement. With each failed attempt at obedience, your frustration and sense of failure grows. Your relationship with your four-legged friend is strained and, even worse, your confidence in your own abilities as a dog owner is at freezing point.

Now imagine that you have found the key to a harmonious relationship with your dog. Your training is full of joy and mutual understanding. Your morning training hours have turned into a time full of play, motivation, drive and success. Your dog responds to your instructions with enthusiasm and enthusiasm that you have never seen before. Every day you witness the amazing transformation of your dog, who has become not only obedient, but also a happy and motivated companion. Your confidence in your own dog training skills is restored, and most importantly, your bond with your dog is stronger than ever.

This ideal world is within reach thanks to CHAMELEON® IV MEDIUM. This revolutionary training collar was designed with your dog's well-being and motivation in mind. These collars were developed by the living legend in the field of canine, Bart Bellon, which ensures that you are using the best that is currently available on the market.

CHAMELEON® IV is not just an ordinary training collar. It is a bridge between you and your dog that allows mutual communication and understanding on a whole new level. With the help of the DOGGIFY APP and wireless technology, which enables easy setup and monitoring, training is not only effective, but also enjoyable. CHAMELEON® IV MEDIUM in combination with CTT 4 and FIGURE KICK allows you to turn everyday challenges into successes and your desire for a harmonious relationship with your dog into reality. 



CHAMELEON® IV MEDIUM is the pinnacle of innovation in the field of electronic collars, which has retained all the great functions of its predecessor, CHAMELEON® III B, and at the same time offers functionality that no other training electronic collars have.

This product offers discretion, comfort and the ability to easily adjust the position of the contact points. CHAMELEON® IV is waterproof and rechargeable using a wireless or wired charger. It uses the latest technology in the field of electronic collars, many of which are patented by Martin System® .

The Chameleon® IV collar from MARTIN SYSTEM® brings you an innovation in training your dog that will take you right into the 21st century:

Thanks to  bluetooth technology,  you have access to Doggify, a free mobile application from Martin System® . After downloading and installing it on your smartphone (both Android and Apple devices are supported), you will get immediate access to a wide range of important information about the collar.

We can thus accurately determine whether the collar is correctly connected to the dog's skin (that is, whether the dog did not respond to the instruction due to ignoring the instruction or due to bad contact of the collar), monitor the dog's temperature (which is very practical, for example, when transporting the dog by car in the summer months), or check the battery charge status. The app also allows users to easily set default stimulation levels and customize the collar according to individual needs for an optimal training experience 

Download the dogiffy EN application


Chameleon® IV is designed to visually and functionally meet the various legislative requirements of various countries where the use of stimulation collars may be restricted. Its design is discreet , which makes it different from traditional electronic collars, which many owners will appreciate.

This collar is equipped with a rechargeable battery that can be charged either via cable or induction, which adds to its practicality and user comfort.

Chameleon® IV represents a real revolution in the evolution of collars. Professionals know the reason.


*Note: the CTT 4 remote control is not included in the package

EN BE-111 MARTIN SYSTEM - Set K9® + Chameleon® III B (Large) + Finger Kick + charging kit-PhotoRoom EN

MARTIN SYSTEM® training collars are an exceptional tool in the hands of dog owners looking for an effective yet ethical way to shape their dog's behavior.

These collars are the only ones in the world that are not designed to correct behavior associated with punishment or aversion.

On the contrary, they offer a unique approach to training that allows owners to stimulate and motivate the dog to the desired behavior, to intervene in their dog's behavior at the exact moments when it is necessary, all while maintaining a fair and safe approach .

Communication with the dog at a distance takes place in a spirit of understanding and motivation , which not only does not traumatize the dog, but on the contrary stimulates a positive reaction and joy from fulfilling commands.

The uniqueness of MARTIN SYSTEM® collars also lies in their ability to provide stimulation through constant,  gentle, low pulses , which makes them the only training collar on the market that uses this approach.

This exceptional, patented capability of Martin System collars is key to safe, reliable and modern training that respects ethical standards while ensuring that the relationship between you and your dog remains strong and positive.
