After a year and a half of absolute delinquent behaviour so bad I will never get another molosser puppy, my dog fooled me.... he has behaved perfectly for the last three months and I breathed a huge sigh of relief thinking that he may have grown up at last. Imagine my surprise and fury coming home the last two nights to a demolished back yard and a repair bill I can't bear to think about. Can anyone give me an insight as to what may have caused this reversion to his earlier behaviour? Nothing has changed in his surroundings, no new people no new anything... Any advice would be MORE than welcome regarding the why and how to fix. Thanks
