There’s a toy you can buy, like a hollow ball, you put some nuggets of food inside, and the dog plays with the ball, and every few turns or so, a nugget pops out. Dog plays, eats a little, plays, eats a little more. Meal takes a long time to consume.

A service dog I know eats this way. It helped her digestion a lot.

Sadly, I don’t know what this thing is called.
