Ah pfr, I think you've hit on the most important part of the subject:
'simply by devoting many hours each day to bonding and walks'.
I wonder if people nowadays don't have the time? Glued to their gadgets and mobile phones, glued to the TV, glued to their sofas.
It must take dedication to devote hours each day to training and exercising a dog/dogs.
I also think breed is important. Some breeds, as I understand it, need lots of outdoor time and stimulation (the gundogs, and spaniels, German shepherds, terriers etc) They aren't simply toys for silly folk to pop in a handbag, dress up in daft outfits or leave indoors all day long completely alone.
