Maybe when we were nomads and the dogs roamed around freely around the tribe.
But most dogs today are locked in, most of the time and when they get outside, they are on a leash. Totally dependant on their human masters.
I don't think I would describe that relationship as a partnership.
Then there is the concept of breeding them, to establish certain "cute" traits, but cause great pain and misery to the animal:

I would argue, the native american tribes, who also did eat their dogs, treated them better overall, than humanity does today on average. So many dogs bred for running around, are lucky today, if they get to walk around outside for more than 20 minutes. This I would call betrayal.
