What do you feed your doodles?

We have gone through blue buffalo, purina one, one ×, purina pro plan beef, and now sensitive stomach/skin salmon. Half way through a 30lb bag he stops eating the food dry. In two instances, he got sick so we temporarily switched him to boiled chicken and rice, then tried to switch him back but could not. I even get him the pro plan sensitive stomach wet food to mix with the dry. I even tried soaking the kibble. He starves himself until I mix the wet food in and even then he barely eats. When we adopted him last year he would eat so fast, I had to get him a slow feeder. He is a 2-5 yo, 68lb, male
