My 3 year old male presa canario mastiff isn't listening when it comes to walks and having other distraction around. If we are in the house he listen pretty good. But I can't control him when he is outside and he has bite 2 people and has went after 2 dogs..I had rescued him 1 year ago and I've looked into training but they all are thousands of dollars which I don't have. And I love him to bits and I really don't want him to be put down but we are on are last chance as I don't know what to do with him. And can't afford the law suits from the person he has bitten ..I really want him to be happy and have a good life ..
