premise: We switched to Purina 1 what he got at the pound , but still he wo nt eat it . He went 2 days without eating before I just gave in and gave him the wet food , but I ca n't afford 1 can per 10 lbs ( 10 cans / day ) of wet dog food every day . I ' ve tried mixing the two nothing will get him to eat . He 's got no energy and he looks so sad . Why wo n't he eat it ?
hypothesis: Because I gave in .
