Hi everyone, As you know, Yalom is 7 months old now. He was well socialised as a puppy and has always been very friendly. However in the past week he seems to have developed a sudden wariness to strangers. I haven't been aware of any events that could have triggered this, and I'm with him all the time. I have read mixed views around a second fear period but wondered if this could be linked to adolescence in some way? Thanks for your thoughts.
