Why Do Pets Eat Grass? There are various conjectures and theories on the subject of grass-eating. Eating grass seems to be a normal behavior for pets, despite what other things we think that their diet should consist of. There have been numerous studies that have tried to find a connection with grass eating and illness, vitamin or mineral deficiencies, or lack of roughage in the diet. Unfortunately, none have produced any tangible connection to any particular problem. Some pets may just like the taste or texture of grass. In the wild, dogs take in grass as part of their diet when they eat herbivores. As a result, they may be accustomed to the flavor of grass, and continue to require it as part of their daily diet. Pets may eat grass because their prepared diets are lacking in greens. As a result, pets sometimes seek out a certain type of grass to eat. Do Dogs Eat Grass to Make Themselves Vomit? Most veterinarians believe that vomiting occurs naturally as a consequence of grass eating, and not because the dog was trying to make itself vomit due to an upset stomach. When dogs eat grass, the grass can act as an irritant and causes vomiting. Is It Helpful or Harmful? Grass acts as an internal cleanser, which in turn may expel mucus and bile. It also cleanses the bowl and can expel worms. Cereal grasses contain enzymes, vitamins, minerals and amino acids. In addition, grass contains chlorophyll, which was once used for relieving pain, treating infections, ulcers, skin diseases and before antibiotics were used. Some pet owners grow grass specifically to give to their pets to prevent or treat diarrhea, anemia, cataracts, fleas, tumors excessive shedding and other pet health problems. Pets that are fed grass on a regular basis are less likely to crave outdoor grass. The problem with eating whole grass is that each blade is covered with microscopic barbs that can cause stomach and throat irritation.
