we had the same issue. Sweetpea is 6 weeks post amp and we started her on a grain free diet a few days postop and she was none too thrilled. She refused can food (which she never did before) and so I went and bought chicken breast in a can and mixed it were her dry food and we had success - good luck:)

I switched Dakota and Evelyn to Honest Kitchen after amputation, though not immediately. In fact, my motivation was Dakota's gradual refusal of almost any food. I don't ever feed him HK alone, though. I mix it with raw ground beef, chicken gizzards and livers, ground turkey, all kinds of stuff. I also mix it with a very high quality kibble that I found, Nature's Logic. (It has millet in it but I had to read about millet and carbs and sugars to understand that it is a very low carb hit.)

Try mixing the HK with a canned food or cooked meat that your dog already likes. If you want to switch to raw meats at some point, you can. If you don't want to, you don't have to. But most people use HK as part of their dog's diet and not the entire diet.

Not all HK forumulas are created equally. I generally use Thrive because it is high in protein, very low in carbs and more affordable than the other recipes that are high protein. Dakota can't stand Thrive on its own. He consents to eat it with enough goodies in it. He really loves Embark. I haven't tried the more expensive ones because he will eat these and I'm not going to completely break the bank. Evelyn, of course, will eat the cardboard box the food comes in. But she's a bulldog.

(For what it's worth, HK seems to be on sale for 20% right now. I bought 2 boxes yesterday at my local Whole Pets, and I am on the regular delivery program from Pet Flow because their price is pretty good.)

Chico didn't like the Honest Kitchen either.  And it comes highly recommended from the Labrador Chat board where I am also a member.  My cats don't like the cat formulas, either.

I'm looking into Earthborn Holistic as his next grain free food.  It's not low carb, though, too many potatoes for that.  I'm not sure I like potatoes but I thought I'd give it a try.

Huh, I thought I posted this too.  With Miller being picky, you could try the raw goats milk that Additional makes.  I've never seen a dog refuse that.  You just put a couple tablespoons over his food.
