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 TUV-certified for safety. TUV-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. The toys are tested to human standards and do not contain toxic or harmful chemicals.
