The parent commenter has probably, like me, heard that pigs are remarkably intelligent. I haven't heard the same of cows.
That may very well be a skewed understanding, but it's likely why they choose that grouping.

They’re just as social and emotional as dogs are.
Intelligence wise, dogs are probably a bit smarter. But how much, I don’t know, they don’t seem that radically different.
I think pigs have just received enough good PR recently that they come to mind as another particularly intelligent animal.
