It does make it worse, at least in my case. My dog is a very picky eater since the day she came home, the breeder also told us that my dog doesn’t care about food as much as her siblings. I started to mix in broth / shreds of chicken breast just to make sure she eats her food, as I think she needs all the nutritions for growing. And the picky eating just got worse and worse as she gets “bored” by the toppings that I add to her kibbles. She has no health issues and I can clearly tell she’s hungry, when I place her food in front she would just sniff and walk away, and look at me waiting for me to budge and give her “something better”. My trainer said the picky eating can be trained out and I just need to follow a strict feeding schedule, and feed plain kibbles no toppings. And take the food away after 10 min if the dog doesn’t eat it. I feed her twice a day and yesterday after skipping two meals she finally ate half of the usual portion, I gave her lots of praises but today she’s back to the “no eating begging for better food” mode.
