Write a short paragraph explaining to a 6-year-old why Wolfie, the family dog, has been eating grass. It's making him vomit and you need to explain why that's bad and how the family can try to get Wolfie to stop eating grass. Tell the child they can distract the dog by playing with it or giving it a treat.

Wolfie has been eating grass lately because his tummy doesn't feel good. He wants to eat the grass because his food doesn't have enough fiber. Can you say fiber? Grass has a lot of fiber, so his tummy tells his brain to eat it! But when he eats the grass, his tummy doesn't like it, so he throws up. So we're going to give Wolfie a new kind of food, so he'll have enough fiber, and his tummy will stop telling his brain to eat grass! If you see Wolfie eating grass, you can try to distract him by throwing his toy. Or you can tell him you'll give him a treat!
