That said, I’ve also dealt with both puppies and picky eaters.
(I have a very long history with dogs. I just turned 37 and have never been without a dog in my life.)
In my experience, it’s best to just pick a food and stick with it. I’ve limited treat intake and have even withheld treats in an effort to get my dogs to eat their food.
Just put the food in the bowl, put the bowl down and leave it. Eventually, the dog will get hungry and eat. Don’t let the dog get the best of you either. You’re the master or pack leader. If you want the dog to eat XYZ, then this is what they’re going to eat.
The only time I’ve ever switched foods is if there was a problem and it didn’t sit well with my dogs after awhile.
I don’t know a lot about food rotation though I know some people do it.
IMHO, it’s really best to stick with one food. It’s something I’ve always been doing from the very beginning of dog ownership and it seems to work just fine. If anything, I’ll usually switch up the different kinds of hard and canned food I’m giving. In other words, I just don’t stick with Blue Buffalo Wilderness chicken. I also buy and feed turkey, duck, beef, venison, etc… . Once I’m done with the bag of duck, I buy a bag of the chicken. When I go get cans, I make sure I have a variety, at least 2 of each protein.
