Yeah I've listened Americans and Europeans love dogs and cats, even Chinese do. But here I guess it's changed in recent times, maybe because there's not much retired population atm.
Actually we live near a canal and there have always been a pavement in both sides of it for about 3 kms, as a kid when I used to go down for a walk there, I remember there used to be 100s of dogs, if not thousands. But now I hardly see only a few.
