Do you want to feed dry only, wet only or a mixture of both?
Here are two dry types you can consider:
Merrick Puppy Plate
Wellness Super5Mix Puppy
And a wet food:
Merrick Puppy Plate Canned
And an adult food that I know is one of the tastiest foods out there (for later... They say you can switch very small dogs to adult food when they are neutered at around 6 months, but it's still somewhat debated..)
Solid Gold "Just A Wee Bit"
Compare the ingredients of those foods with the Euk (or as some people here call it, "Pukanuba"...
), and you'll see that the ingredients are much closer to real foods...
You can look around the dog food forum for other threads about picky eaters and about choosing food.
Also make sure you switch very gradually (over the course of a week or two) because switching foods is very hard on a doggy's stomach.
