What's the difference between slavery and having dogs?
I mean when they do good we give them treats
same as when a slave does good we give them small incentives
when they are bad we punish them
the same thing with human slaves
we either are good dog lovers or dog abusers
the same as good masters and bad masters
we transport them numerously
the same with human slaves
we breed them
the same with human slaves
we give them this food called "dog food"
which is a low quality  food given to human slaves
and the most obvious of all is dog collars and chains as to categorized them as property and to subconsciously "oppressed" them.
So is having a dog wrong?
A lot of people seem to treat dogs correctly
the dogs seems nice and happy
So was slavery okay?
I really don't know
