Isn't Cainan a lab? And isn't he still a puppy?
Any puppy I've had has had the attention span of a gnat. That's just a puppy for ya. The labs that live in my neighborhood I have watched over a period of years..........it takes them at least 2 years to calm down. There are 5 labs in very close proximity to me. It took the one across the street 3 years to settle down.
