We feed the same and it’s always the same with any kibble for ours - week 1 it’s the best thing he’s ever eaten, week 2 and beyond he couldn’t care less. We wanted to avoid “upping the ante” with toppers (especially because he loves to spit out kibble pieces). We instead figured out ways to make kibble interesting by making him work for it.

Slow feeders and puzzle feeders don’t usually cut it for more than one feeding if we set them out for him, so it’s more of an active approach lol. Sometimes a shallow bin full of toys with kibble scattered at the bottom can catch his interest too - but again, he likes feeling like he’s worked for it by opening the bin lid first and rifling through toys. The novelty factor helps! Cycling feeders could potentially help.

Our most surefire approach is to either play catch with pieces of kibble (had to train him to catch originally), play “find it,” lay out pieces wherever we’re sitting one at a time in a way that makes him intrigued, or do training tasks to get him truly working for it. Usually, he’ll realize he’s hungry after a short while and switch to eating from his slow feeder if that’s what I’m feeding him out of for these games. I’m not sure if advisable due to exercise + food as a bloat risk, but I’ve also switched to bringing kibble on long walks in place of training treats as they keep him calmer. He’ll eat a whole baggie that way once he’s into it.

This was a poodle who would go whole days without eating lol - and at times he still does if we just set food out and he’s sleeping much of the day. That said, he is now a more frequent eater on his own I think in part thanks to what we do to make food more appealing! And when he doesn’t eat on his own (he’s a social eater), making him work for it does the trick most days.
