I will I wanted to try raw with her but I don’t know yet I’m doing research about it I don’t like her on dry food really I asked them to keep her on wet food

She loves wet Food but before I gave her up I would give her wet food. But I was gonna try freeze dried treats what’s your thoughts on that is it worth it is it healthier then the crunchy treats
