Dogs and cows might be entirely different animals, but grass eating is on the top of their list of commonalities. (Right behind “mammals.”) Though dogs don’t graze like bovine, they still munch on grassy roughage regularly enough for you to express concern. Which brings about the question: Why do dogs eat grass?
First, be assured of the general safety of this snack. Now, let's highlight these facts:
- Dogs eat grass in the wild. In other words, it’s usually completely normal for dogs to chow down on greenery. If the amount consumed is large enough to be a concern, you might recommend a full examination.
- There could be several harmless causes for the behavior. Some people believe dogs do this when they are unwell in order to induce vomiting. There’s little evidence of that, though grass eating can make some dogs harmlessly vomit.
Some people are in the “nutritional deficiency” camp and usually suspect a fiber deficiency, a result of years of domestication. The idea is this: Wild dogs ate an animal’s full body, including the fibrous grains that the animal had previously ingested. Our beloved pets of the current day don’t do that. In fact, they rarely include grains or vegetables in their diets. But they are omnivores. A diet change or a good supplement can support comprehensive nutrition.
Still others are sure the act is meant to aid in overall digestion—a similar mentality. Again, diet changes or supplementation can help if you truly want to limit their pup’s grass intake.
- Pesticides and herbicides can be toxic. If you only catch your dogs eating on your own lawn, pesticides and herbicides are lesser concerns. But if they’re out at a dog park or other public arena, it’s always good to err on the side of caution.
Dogs like to eat. That’s no secret. Why they eat what they eat is kept a little more difficult to comprehend.
