What if every meal was replaced with an enriched one

What if instead of having their meal placed in a bowl twice a day. I hid their food in towels/slowfeeders/around the house.

My thought is, these dogs were hunters and hunted for their food in the past. why don't we enrich and feed them at the same time for every meal? This would keep them busy for at least 2 hours a day and exercise their brain.

I will do this when the puppy is older of course. let me know your thoughts, I'm getting a puppy soon.
