MAJORDOG products were developed in Sonneberg Germany, the Toy Capitol of Europe, through intense collaborative efforts between trainers and dog owners.All of the training items and toys are designed, tested and TÜV-certified for safety. TÜV-certified means that our dog toys have undergone and passed the same rigorous contaminant testing as a child's toy. MAJORDOG toys are the world's first to do so. Our toys are tested to human standards and do not contain toxic or harmful chemicals. MAJORDOG's development phase lasted several years in order to guarantee the highest standards for quality and function. MAJORDOG products are perfectly designed to meet your dog’s needs and are distinguished by their high-quality, durable materials. MAJORDOG uses a high quality natural rubber which is stronger and safer than standard dog toy rubber which makes it very robust and durable while still remaining gentile on a dog’s mouth. The rubber is also safe for the environment. MAJORDOG’s Whirl toy has a unique four armed shape ensuring that no matter how you throw this toy it will always land with one arm sticking straight up, the arms also allow for some unusual movement to keep you and your dog guessing where it will land.
