My dog still got intestinal cancer anyway.

My title sounds like something Debbie Downer would say.

'Dogs and cats have been eating grass for a long time. In fact, grass is so popular among dogs that one species, dog grass, is named after them. Dog grass is also known as couch grass and quackweed, and it grows in all but the southern-most states.

You can think of grass as an herbal medicine. It acts as an internal cleanser, expelling excess mucus, bile, and other impurities. It also cleanses the bowels and expels worms. Cereal grasses contain enzymes, vitamins, minerals, and amino acids. Grass also contains chlorophyll, which was used for relieving pain, treating infections, ulcers, skin diseases, and anemia prior to the use of antibiotics.'

Why do dogs eat grass?
