I just went through this with my almost 11 month of lab. The whole thing came about suddenly and one day eating everything and the next picky. I did everything you should not do, added can food, sweet potato and honest kitchen proper toppers. Nothing worked so I called the breeder. She told me to put him in his crate, leave him for 15 min and then take away what he didn’t finish. I have another lab, 7 years old, and she told me to feed her right next to crate…VOILA, he is eating perfectly again with no additions to his food except a probiotic. It is a bit like dealing with a very stubborn toddler.
