my pup wont eat

Question
I have a cocker spaniel she is now just 7 months old, I got her at 2 months old. She is surviving but I don't know how. I started her on Science Diet she didn't like that so I went to eukubana puppy food (dry) I tried putting in a spoon of wet food, bread, crackers anything in there to get her to eat something. She eats her food about every 3 days, I tried Benefiful by Purina , she turned her nose up to that to.  How do I get her to eat. She only weighs 13 lbs. shes so skinny.  She has been vet checked several times and tested for worms, she has had all her shots and was fixed at 5 and a half months old. If I accidentally dropped something on the floor she would eat that in a minute, My guess is she just don't  like her food. Any suggestions???

Answer
Yep. Throw all those foods away LOL. Get Flint River, Wellness, Natural Balance or Eagle Pack. They are pricier, but you will not be paying for fillers that are just being pooped out and cleaned up by you :). Your dog will eat less and in the end the food will cost less.
Put her food down twice per day for forty five minutes per meal.
No treats in between. Let her either eat or not eat. She eventually will,
Beyond that, take her to the vet and make sure there is nothing else wrong, thyroid , bloodwork etc,
Good luck
