Questions about Pug's eating habits?

I recently adopted a 1 yr. old pug from my cousin who had a baby and couldnt keep him anymore. When I got him,she warned me that he eats ALOT and that she had him on weight control food which she gave to me. Well partly because we were so excited to have him and we wanted him to feel at home, we gave him lots of treats and I the first few days, I mixed some gourmet dog pate in with his dry food. Now its all gone and he wont eat his dry food alone. He just lets it sit there all day and will only eat it if I give it to him from my hand. I dont want him to starve. What should I do?

Also wanted to mention that she was feeding him Beneful weight control and I switched it because the guy at the pet store said that Natural Choice was better cause it didnt have dyes and lower calories and he ate it just fine when I mixed it with the pate crap. Now he wont eat....ughhhh!
