I have taken Lulu off commercial dog food, and I am feeding her meat and vege. in 80/20% proportions (not quite the raw diet yet, but we'll see in time). What I want to know now is how much to feed her? Before I just fed her the amount it said on the bag, but now what if I don't give her enough? I can't stand the thought that she might get hungry quicker between meals--especially in the middle of the night because I have only been feeding two times a day. I need advice on portion size and times per day with human food. Thanks so much!
