I don't know what your previous issues were, but I'll state my opinion upfront -- No Pedigree.
Now, I don't think that kibble and raw can't be intermixed. There are some commercial foods (including kibbles) that are formulated with an eye toward raw. I like Instinct by Nature's Variety for this very reason (Nature's Variety sells raw products as well). But other
grain free foods, like Wellness, Evo, etc work well too. Why? Because these are premium-quality, high protein foods, similar to the raw food that you're feeding.
But honestly, the Instinct I buy (my GSD eats it in emergencies only) costs $49 for 23 lb bag. That's $2.13 per pound. That's more expensive on a per-pound basis than much of the raw meat that I buy for my dogs. So if my dogs LOOK like they're not getting enough food (and snorffeling around their plates after dinner doesn't mean they need more food. It means they really like the food they had, and want more. Kind of like me and the plate of brownies.
), I can give them an extra chicken drumstick for $1.19 per lb. That's a heck of a lot cheaper than
appropriate kibble.
If they're losing weight fast, I may need to rethink the meat I'm giving, or supplement something that's fattier than meat, like low-fat cottage cheese and eggs (my GSD eats these almost every day). But the thing is -- and I think we all do it at first -- we ALL have been, well, indoctrinated that commercial food is the only "complete and balanced" way to feed our dogs. We get nervous. We worry, what if they're not getting a balanced meal? What if I'm not doing this right? What if they're starving? (And they love the new food so much that they act like they're starving,
which doesn't help! ) But it takes time for your dogs to get used to their delicious new diets as well as for you to decide exactly how much each one eats and what, if anything else, you're going to feed.
I've been there. I recommend that you simply go with the process, as Patti recommends and work things out over the next week or two (it doesn't take very long). But you can supplement appropriate kibble if you want. A lot of people do with absolutely no harmful side effects. But you don't need to. And it may be cheaper to simply feed more meat if you need to.
BTW, my guy eats 4% of his body weight. He's an active working dog. So it does take some tinkering. He was hungry in the beginning. But he didn't starve. Though he sure acted like he was!
