Wondering if I've done this right.
A month ago I started my now 8month old pup on a ready made pre packed raw diet. It's working really well and happy with it. I add a sardine nearly daily as my pup is OBSESSED with them 
Now, I thought I'd be generous and when doing my food shop picked up a pack of beef chunks and a pack of lambs liver. I've separated 1 liver and 2 chunks into sandwich bags and whacked in the freezer. Can I take them out, let them defrost in the fridge like I do with his food, then just add them on his food?
