Our younger lab will be 3 in March. We have survived the puppy stage and then the 1-18 month adolescence stage. Mostly he is great and trots on with his older 'brother' lab on walks and recall is fine. BUT sometimes, and it may be food related, he stops, sniffs the air and is off to the cricket club ground, or to see another person or to greet another dog. Today I was told by an acquaintance that it was about time he learnt to be disciplined. She has a black lab that just meekly follows in her footsteps - same age actually. So do they go through another stage of not listening or being over friendly? As you may tell her comment has upset me.
