Hi people and little furriers

I am having some problems with feeding my little Pip she is 11mo wt aprox7pds . I am feeding her a freeze-dried food called Stella & Chewy's it is grain free as well as not having all the stuff you don't want artificial preservatives ,glutens color suger etc etc . She ate it really well at first and seemed to like it ,it comes in 4 or 5 different meat sources . I also give her raw bones from organic chicken as well as the meat she LOVES the bones ,I give them after she has eaten, partially frozen so she chews them well. In the last month or so she has been refusing to eat her food . I cut back on treats, she is eating a little more but not what she needs for proper health! I have tried mixing her organic chicken with the freeze-dried, but she just does not want to eat it . I even bought some Wellness puppy food ,she does not like it either . I cannot feed just raw chicken anybody have some advice for me????
