Dogs Eating Grass: Why Do They Do It - Is my Dog Poisoned?

Our Brighton veterinarians are frequently asked why dogs eat grass and whether it is safe. Today, our Horizon Veterinary Clinic team will share some insights on why dogs eat grass and when you should be concerned.

Why do dogs eat grass?

There are several theories as to why dogs eat grass. While we may never know the exact reasons for each dog, some common explanations include:

  • Nutritional Deficiency: One theory is that dogs may eat grass to compensate for a lack of nutrients. Grass contains specific vitamins and minerals that may be missing from their regular food.
  • Instinctual Behavior: Dogs' wild ancestors were known to eat grass and other plants, possibly to aid digestion or to help purge parasites. This instinctual behavior may still be present in domestic dogs.
  • Digestive Aid: Some dogs may eat grass to help with digestion. Grass can act as a natural laxative, helping to move things along in the digestive tract.
  • Gastrointestinal Upset: Dogs with upset stomachs may eat grass. This can induce vomiting, which might help them feel better if they've ingested something that doesn't agree with them.
  • Boredom or Anxiety: Dogs that are bored or anxious might chew on grass as a way to pass the time or to cope with their feelings. This is particularly common in dogs that do not get enough mental or physical stimulation.
  • Enjoyment: Some dogs enjoy the taste and texture of grass. It might be as simple as them liking the way it feels and tastes.

Is It Safe For Dogs To Eat Grass?

In most cases, dogs are safe to eat grass, especially if untreated and free from harmful chemicals. However, monitoring your dog's grass-eating behavior and how often and how much grass your dog is eating is important.

Occasional nibbling is usually not a problem, but frequent or excessive grass consumption might warrant a vet visit. Ensure your dog gets a well-balanced diet that meets all its nutritional needs.

This can help reduce the likelihood that they are eating grass due to nutritional deficiency. Watch for issues such as vomiting, diarrhea, lethargy, or changes in appetite or behavior. If you notice any of those symptoms, consult your veterinarian immediately.

Is eating grass an emergency?

While it's generally not harmful for dogs to eat grass, there are some instances where it could be a cause for concern:

  • Pesticides and Chemicals: Grass treated with pesticides, herbicides, or fertilizers can be toxic to dogs. If your dog eats grass from treated areas, it could lead to poisoning. Signs of poisoning include vomiting, diarrhea, lethargy, and seizures. Contact your veterinarian immediately if you suspect your dog has ingested toxic substances.
  • Choking Hazard: Sometimes, long blades of grass can cause choking or become lodged in a dog's throat or nasal passages, leading to discomfort or breathing difficulties.
  • Underlying Health Issues: If your dog eats grass and vomits frequently, it might indicate a more serious underlying health issue, such as gastrointestinal problems or nutritional deficiencies. It's best to consult with your veterinarian to rule out any health concerns.

Understanding why your dog eats grass can help alleviate your worries about this behavior. While it is usually not a cause for concern, it's important to be aware of potential risks and to ensure your dog has a balanced diet and plenty of mental and physical stimulation.
