Hi All! My nuggie just turned a year and a half and we recently moved. All of the sudden if we take him with us somewhere or go on a walk if he sees a runner or walker coming by him he will start to get aggressive and lunge at them when they get close. This is a new behavior that he has just recently picked up since the move. Wanted too see if anyone else has gone through this and what we can do. Already looking into trainers as I believe this is fear based because he is a super happy loving dog! Any advice/tips would be great. Also, the hard part is he is hard of hearing so would have to be non-verbal training. Thank you in advance
