Robin, I know some people with dogs that eat so fast that they inhale, and seem hungry afterwards so they feed in things like a Buster Cube. One of my agility friends feeds 1/2 portion as a “Regular” meal in a bowl, and then the other half portion in something like a Buster Cube to slow him down and extend the time it takes for him to eat. It’s not a weight loss tool in itself, but I think sometimes dogs eat so darned fast that they think they’re starving because feeding time is over in .0005 seconds 😉
Even if you’re concerned about calories (in yogurt), you can literally dilute the yogurt with water if you choose to feed and freeze (in a kong).
I know some Golden Retriever people who swear by green beans to help with weight loss, as Goldens seem to put weight on easily. Rapid weight loss in encouraging at first, but not always safe, so be cautious if you see dramatic loss early on.
