Not quite. Family pets, guard dogs, ect, trust and serve their owners, not humanity in general. I'm not a party to any agreement or contract with dogs.
We have not bred cows to have the same level of attachment to us... their personalities have not been nurtured to adore and seek our affection, and they don't perform work for us in the hope of gaining our approval.
We couldn't get cows to be like dogs if we wanted to. What dogs do is half genetic.
Our contract with cattle is "free food".... I think our contract with dogs is higher.
I don't think "we" have a contract with either dogs or cows. The alledged parties are to numerous, varied, ignorant of this supposed contract, and in the case of the animals, unable to think abstractly for any contract to exist.
Obviously mine is an abstract argument that your aren't able/willing to consider either. OK.
