She has indeed been eating eating. Buttercups. Pieces of mushrooms. Goat poop. Horse poop. Interesting things in the woods and meadows. Good news is that she loves going outdoors and is able to get "manic puppy mode" worked out of her system when we walk off leash, just romping for half mile or so. But yes, there are delicious smells and tastes.
