When did your Collie start settling down from the puppy stage? My gorgeous boy is now 18 months old & slightly calmer than the manic small puppy stage, but he is still very bouncy.
I have had quite a few Collie owners I have met on dog walks mention to me that they saw quite a change in their dog once they got to 2. I was wondering if that was the case in your experience.
We have no particular issues really behaviour wise & have recently graduated on to advanced level at our weekly training classes. Just curiosity really.
