No, this is a myth. When they eat grass, they are in need of chlorophyll and healthy greens, as they are not getting enough of it in their diet. Not sure how this translates to him eating twigs though.

When you feed a raw or homemade diet, rather than commercial foods, you are adding these healthy greens in the mixture. These dogs and cats don't eat grass.
