Mmmmm...semi-frozen, raw meat...sounds so tasty.
Just kidding, I'm sure to a dog...or most dogs...it's a yummy treat.
I would just give her time. Make sure that she doesn't go
too long without eating though. I tried that whole 'she'll come around and eat it eventually' theory, had a dog that would eat only what she absolutely had to and got to visit the ER vet as a result.
And this was all in a matter of less than 3 days time.
Maybe you could gradually switch her over...add some of her other, cooked food in with it and gradually change the ratio to include more raw?
I'm not an advocate of raw in the least bit, but regardless, I don't think I would change food cold turkey (no pun intended) on any dog.
Good luck!
