I would have to say that even when Bruno was a little puppy, he received at least one out of 4 meals per day in a puzzle toy of some sort. Either a wobbly tower thing that he had to push around for the kibble to come out (with awesome adjustable levels for varying difficulties and kibble sizes); a treat-dispensing ball; or a small Kong. Normally within just a couple minutes he had figured out the toy and was happily finished with his meal within 5 min or less overall, from serving to the last bite. He also seemed to have a lot of fun and is always excited to see those toys, because they mean fun and food for him.
Nowadays he has about 2 meals per week (randomly chosen, without toppers, just the kibble) come out of toys and he still loves it. We have gotten 2 new puzzlers and use those, and the good ole tower and ball (the Kong got lost in our last move, still need to get a new one). Also, the RMB he gets every Sunday evening he doesn’t get in a puzzle or treat, but spends some extra time working on as it is, well, an RMB.
Personally, I wouldn’t feed ALL meals from a Kong or a treat dispenser/puzzle of any sort because I like to keep using toppers for his kibble and don’t want the mess, but on occasion, I would totally use them for some of his kibble-only meals. 🙂 And I wouldn’t put raw in a Kong or a puzzle toy either.
