It is puppy food (I feed proplan puppy) canned puppy food, whole milk (warmed) and hot water with a few globs of yogurt (get their gut bacteria started now). Remember I'm feeding 12, you are feeding a bit less, hhe.
Anyway, every creature in my home LOVES this mix. I make it pretty wet, they lap up the liquid andt hen eat the kibble bits. They are also starting to drink water, but get a lot of moisture from this mix.
I had to wrap my mind around using milk. I dont think we have puirchesed milk for a good 15 or more years, but now I have it down and there is a gallon of milk in my fridge.
I would not free feed. Feed every 3-4 hours. She can go the night. If you have to leave her for work, then leave food in with her. She needs to eat a lot. She wont eat huge amounts each meal but she should eat regularly.
