pedigree health&vitality large dog

Hi does anyone feed their dogs this semi moist complete.
Chloe our dane wont eat raw meat, we have been feeding her mixer and canned dog meat.
She is 3.5 years old and is 50kgs but very ribby and bony.
Have also looked at fold hill betterbake complete as well.
If anyone uses either of these foods i would like to know your views. MICK.
