Yep, soooo agree. There is a whole generation of kidparents who haven't a clue in the rules of owning a dog. They think 'oh, we're home all day now, we'll get a puppy for the kids'. Give me strength.
As a dog owner of many years, and talking to other regular dog walkers, we're experiencing the same thing re dog poo. Noticeable (and look away if you're of a sensitive nature) is the size of the turds !! that get left. Clearly larger dogs leave their deposits the size of submarines, yet owners of these monsters never pick up after them. And again, in all my years of walking, I rarely, if ever, see a man walking a dog with a poo bag in his hand.
