The best piece of literature I've seen regarding cow intelligence and social capacity was measured in terms of their ability to bond and empathize with other cows, their ability to bond with humans didn't come close to that of dogs
Rats form extremely close bonds with their human companions, and anecdotally I have family in Mexico who have told me about their cows that have tried cheering them up when they were sad.
