The Two Gentlemen of Verona
Lance to Proteus
When Lance tells us about all the beatings he's taken for his dog Crab's bad behavior (stealing pudding, killing geese, "a pissing" under the Duke's table, etc.), it becomes pretty clear that he's more devoted to his dog than Proteus is loyal to Julia and Valentine (4.4.1). Read more about this by going to our "Characters" section.
