From what I've read, some vets, behavior specialists, & breeders disagree as to how long it lasts, but there is a developmental "window of opportunity" during which a puppy learns to be social, trust strangers, and develop a pattern of how to assess social situations. Of course your fur baby is way past that - but I'll bet you can rehab somewhat. Like what you would do with a new puppy - create social situations that are favorable. A little at a time & slowly increase. Maybe have people give him tiny pieces of treat so he learns they are fun? Also really, really praise him when he IS appropriate so he learns that behavior gets positive attention? A lot of work but worth the try. |
