As the title says really! My 9 month old Labrador is only our second dog so my experiences are quite limited. At the moment she is an absolute joy to walk, her recall is solid (she's whistle trained), she has almost zero interest in other dogs and people and she never strays far. I've been reading a lot about the dreaded teenage years but I can't find anything that confirms or not whether ALL dogs will forget all their training and turn into absolute horrors!
Is it possible that she might stay as she is or is it only a matter of time and should I be preparing myself?
