First off OMG I didnt know it was $85 for a 29.7lb back this is the first time I got the big bag. Ok so my girl is around 95lbs...since this is a higher protein and high cal food...how many cups total do you recommend a day....she seems to love this food a lot better than the blue buffalo lamb and rice I had her on....so I don't mind the price but as far as serving what do you all suggest.
