I dogsat for the two of these and I’m not 100% sure of their names, which makes me a bad person. But I do think the little scruffer is Horacio (or possibly Horatio?) and the big goofball is Dara.
Horacio the Yorkie is an older pup, Dara is a young goofball. And Horacio steals all of Dara’s food because of course he does.
