We haven't fed Preference because it isn't considered a complete food, you MUST add meat to it.
The review I wrote was of Keen & Embark. That's here: https://www.chihuahua-people.com/show...Kitchen+Review
If you feel you can be dedicated about adding healthy amounts of meat to Preference, you might as well. For me I wanted convenience but I didn't want kibble. So...we can add nothing or we can add lots of different things to our dogs THK, which I like.
I generally add in things like Ziwipeak, Eggs (raw or scrambled, shell always included), Cottage Cheese, Yogurt, cooked hamburger meat, raw or cooked ground turkey, or sometimes (I know many will shake their finger at this one ha ha ha), but just the tiniest bit of shredded cheddar or mozzerella. I don't see why my dogs shouldn't enjoy their food too, and man do they ever!
Sometimes they also get a bit of canned meats mixed in, the ones with NO SODIUM added. They still have some sodium but my dogs aren't getting so much of them that I worry.
I am sure to include raw meaty bones in their diet. This includes chicken wing drummettes that aren't enhanced (be careful, some are pumped full of salt) that are entirely RAW. They eat the bone too. This is their evening meal a few times a week. Bryco is allergic to chicken so we are still working out what seems to work for him but are trying bone in turkey but its not the easiest to find in small bone-in portions. Its important that they get the bone for dental health. They also get soup knuckle bones, but be aware if your pup is a STRONG chewer, they CAN BREAK THEIR TEETH
Laurel doesn't get the beef knuckle bones because she is too strong of a chewer, but the other three get a good workout from them.
In my mind, with THK, you want the convenience of kibble with some of the healthful benefits of raw, which I have seen occur in my dogs. They are doing much better on this diet than they ever did on kibble. Is it more expensive? For us, yes. It's about twice the cost of kibble. We were paying so little for food as it is doubling the cost was feasible for us, but some don't feel they can do that and so you do what you can do
I'll be honest and say I personally don't see the point of preference because it's not complete. If I need to slap down some food on the fly I want to be able to do that. Having to add meat makes that a little more difficult. The first ingredient in most of the other THK foods is MEAT, which can actually be trusted as the #1 weighted food in the mix, because all the ingredients are listed per their wet weight...to me its invaluable to already have some meat there and in a semi-raw state just waiting for me to add water
