Trust me. I had a picky eater....that I created. Yes, I created a complete monster.
You're not the only one.... I don't know how many of my clients accidently teach their dogs not to eat their kibble. It's true that a dog will not eat as much if he doesn't like his food.... My dog used to skip meals often (she went as much as 4 days without eating, and she's a chihuahua) on the first brand of food I had her on, and after about 6 months I switched brands. On the second brand I don't recall that she ever skipped a meal. BUT, I switched brands because I wanted to upgrade to a better brand, not because I felt sorry for her for not eating. Dogs will not starve themselves. If she doesn't like the food she might decide not to eat it.... but if you make the food more enticing after she decides not to eat it, you will be teaching her not to eat the plain kibble.
