The Question
“Hi Dr Paola,
What do I do if Bobby ate grass?” – Bob
Quick Info about Bobby
Hi Bob,
When a dog like Bobby eats grass, it’s often not a cause for immediate concern. Many dogs graze occasionally, and while it can seem puzzling, it’s a fairly common behavior. Some dogs eat grass simply because they enjoy the texture or taste, while others may do it when they’re feeling mildly nauseated or experiencing minor digestive discomfort. It can be a bit like us reaching for herbal tea when we feel our stomach a bit off. Other theories include that they might just need some extra fiber. In fact, several scientific studies have concluded that dogs on low-fiber diets are more likely to consume grass, and introducing fructooligosaccharides or a high-fiber diet can reduce this behavior. The behavior may also be instinctual; remember that dog ancestors consumed whole herbivores, including their stomach contents, which often contained plant material.
However, it’s important to keep an eye on how Bobby is doing afterward. If he seems perfectly fine, continues to eat, drink, and play normally, and passes normal stool, then a little grass likely won’t harm him. If, on the other hand, he starts showing signs like repeated vomiting, lethargy, reduced appetite, or abdominal discomfort, it’s best to seek veterinary guidance. Always be mindful of where he’s grazing, too, since treated lawns may contain chemicals such as fertilizers, herbicides, and insecticides that could be very harmful to him. If you know Bobby enjoys grazing, it’s best to allow him to do it in a yard you are sure is free of potential toxins.
Best,
Dr. Paola
