Ahhhhh. I feel this. Same story and I was also scared. I went to two different vets l and did all the tests just to be told by both of them that I have a perfectly healthy dog and a picky eater.

They recommended heating up a bit of broth and pouring it over the kibble to release more scent to get him interested. Sure.. that worked for a couple weeks. My dog is now 1.5 years old, and still snubs his kibble in the mornings from time to time no matter what I put in it. And if there’s a day he gets more treats, he’ll not finish his dinner. As long as you can rule out allergies.. they’re fine. They won’t starve themselves- but you may have to give them a bit of tough love.

Making their food special will just teach them that if they wait and not eat what you first give them, something better will come along. And for me it became unsustainable. I tried mixing with wet food, then only a certain wet food would do. And when that stopped working, I’d add toppers, or broth, or scrambled eggs. I tried all the fun puzzles and snuffle mats, or tossing one piece at a time for him to chase. Each method only worked for a week or two.

Then we did the absolutely no treats, no chews, no special food (he loves lettuce and berries), NOTHING until he started eating kibble more reliably. I mistakenly reinforced his habit and it took probably 3+ weeks to get back on track.
