I feed raw so id say get her onto a proper raw diet (and mince alone is not that), and ditch the complete.
It suits my dogs and it suits a lot of other peoples dogs and honestly.. dogs that it DOESNT suit are unusual and without wishing to be offensive 'abnormal' (in that meat... is a dogs natural diet).
I have (and am and will again more than likely) fed very young pups on a raw diet and found it does them the world of good, encouraging chewing in an acceptable way, (which deflects unacceptable chewing of everything you own), creates nice firm relatively smell free poos, good skin and fresh breath.
Read through the threads on here, some feed raw and some feed complete, and some feed both so theres plenty of info on here.
