What's the top dogs' dinner for taste?

I find food that smells good makes my picky eater much more interested. I guess it's obvious as dogs' noses are so much more sensitive than ours, but which type of food gets your dog's nose twitching the most?
I have a young dog that really seems to find little joy in eating her 'proper' dinner, it's so depressing picking up the bowl to find hardly any food gone so I have got used to trying to tempt her!
I have an enormous sack of dry food that breeder insisted I feed, but I find I have always have to add something extra to get her to eat any.
I don't always have a suitable leftover from our human dinner and would like a reserve of prepared food in the store cupboard to tart up her dinners.
What do you suggest?
When I have eventually finished this sack can I switch her to all wet food that she so obviously prefers? Which one is the tastiest? What's worked for you?
Hattie is a Cocker Spaniel, so not a huge dog. She's fully grown now - but how she's managed to grow eating so little I have no idea! The vet has checked her he can't find anything wrong with her apart from having gourmet tastebuds!
I've tried the 'pick it up and put it down' till she eats it philosophy but she held out for two days last time and I couldn't keep it up it made me so unhappy seeing her go hungry.
The breeder insists this dry food is the best, but my instincts say not for our Hattie! It really would make me happy to see her enjoying mealtimes.
