Oslo Hundeskole, established by Jan Geir Marring in 1992, is one of the oldest and largest dog schools in Norway, with 16 departments and over 100 instructors spread from Tromsø to Vestfold. The school specializes in a range of courses for dogs of all ages, including puppy courses, everyday obedience, passing training and competitive obedience. The instructors have a background from the school's own instructor training, which contributes to a high professional competence and quality in the teaching.
In addition to the traditional courses, Oslo Dog School also offers online courses for flexible learning and a summer camp for children and dogs, which promotes interaction between the two. The school has a particular focus on solving behavioral problems in dogs, and during its more than 25 years in the industry has developed a broad competence that few other dog schools in Norway can match.
