It wouldn’t be “starving” her for a day. Most places that recommend raw diets, also recommend “fasting” for a meal, or even a day. I do that on Sundays. I will give my dog her a.m. meal and then not feed her again til Monday a.m. meal. Oh, my dog is also raw fed.
One suggestion, have you tried feeding raw green tripe? Most dogs LOVE it, I know mine does. Maybe offer a meal of that after you fast her for a meal, or a day and see if she will eat it. I bet she does.
I know you haven’t been feeding her raw for long, but have you been rotating proteins yet. Maybe try giving her something different for a while and then go back to chicken or something. There are somethings my dog has gotten tired of and refused to eat, so I pretty much just tried other things and left the stuff she doesn’t care for out of her rotation. I might try to go back to them after a while though…
Good luck!
