Puppy food ideas

Hi, My puppy is no loinger enjoying his food. We gave him a bit of duck today and he loved it, serching round for more, lol
Is there any other things I can cook up for him or anyone have any recipes i can do for him in between his own food (something more interesting) cant be fun to eat the same thing bless him.
Thanks for your help

I'd be wary of fiddling about with his food as it can make a rod for your own back as they get fussier and fussier.

Pick a good food that suits him and you and stick to it
