This sounds like my Izzy for the moment we got a=her at 13 weeks old till about 2 months ago.... We tried EVERY kind of wet, dry, food roll food under the sun..really.. we even tried BABY food...although out of all of them we had the best luck with wet food... she ate Natural Balance venison and sweet potato but only about 1 tablespoon at a time...sometimes she would eat more.
Then that got old and we went to the Food roll that natural Balance made...kind of like sausage for dogs... she liked that for while... then we went to Wellness... that was "ok" but didnt last long..lol
Finally I took the plunge and tried the RAW dog foods... SHE LOVED IT!!! She's been on it for about since end of July and she still loves it... Right now we are on Natures Variety because the one i want is not sold anywhere near me... Which is Primal....but for now Natures Variety is fine... they have lots of different flavors so we switch it up every time she needs a new bag.
I really recommend feeding RAW...Her coat is beautiful and she's at a good weight...and i know she's eating. That itself is worth it.
Good luck!!!
