When we bought our Presa Canario simba, we had no idea what a hand full he would be. He was disobedient and it was a nightmare to take him for a walk. We searched on line for a company that could help and found protection dogs. The team were fantastic with Leedor owning bull breeds him self we were sure Simba was in good hands. He has come back to me a different dog he is obedient and I couldn’t recommend them enough.
