You may have noticed that your pet dog sometimes eats grass. This may even be followed by vomiting. This behavior has long been a mystery to experts and pet owners alike. Even today we are not completely sure why dogs eat grass, but there are three main theories to explain this behavior.
Why do dogs eat grass?
The first theory is that dogs eat grass because their stomach is upset or if they have something stuck in their throat. The idea is that the grass induces vomiting and helps them to feel better. Some experts believe that unchewed grass may have a tickling effect on the stomach, which induces vomiting.
The second theory is that eating grass relates back to the ancestors of the modern dog. These ancestors would have eaten various plants as a part of a balanced diet and when they were unable to catch or find other food. It is believed that modern dogs still carry these instincts and this is why some dogs seem to graze more like cattle.
The third theory is based on the fact that dogs require a balanced diet to remain healthy. The dog may simply crave, or enjoy the taste of eating grass. If you think this is the cause of your dog eating grass, it may be a good idea to give them some green vegetables to eat.
Of course, both these theories may be correct for different animals. For example, some dogs happily eat grass every day while others only eats it when they are feeling unwell. What we do know, however, is that eating grass is not something to be overly concerned about. The only times you should be concerned is if it is unusual behavior for your dog or if you have used poisonous fertilizers or pesticides on your lawn.
