glad to know its not harmful. What about bark and pine cones? I turn around and my puppies go for the first pine cone they see. Then, about thirty minutes later, they are throwing it back up. I was up all last night with my pommy throwing up. I know it was the pine cone she ate earlier. I chased her all over the yard trying to get that thing!
By adding this sort of roughage to their diet, they can keep their digestive tract healthy and clear. It can induce vomiting for an upset stomach. Another reason: wild dogs eat all of an animal, including the grass that it was on. They don't get that in their diet anymore. The last reason is that it just plain tastes good.
