Why Do Dogs Eat Grass?

As a dog owner, you might have observed your furry friend munching on grass when they're outside. 

This may have you wondering why they do this. 

You're not alone in pondering this question; many dog owners have asked the same thing.

Reasons Why Dogs Eat Grass

1. Grass as a Source of Fiber

It's commonly believed that dogs chew grass to help with digestive issues. However, research shows only about 10% of dogs exhibit signs of illness before eating grass. Grass is a good source of fiber, which helps maintain your dog's digestive system. A lack of fiber can lead to digestive problems, so eating grass might be a way for dogs to improve their digestion.

2. Stress-Relief Behavior

Another reason could be related to your dog's psychological needs. Dogs are naturally attuned to their owners' routines, and when they're left alone, they might experience boredom or anxiety. Chewing grass could be a way for them to cope with these feelings, similar to how humans might bite their nails. To address this, you can introduce new toys or comfort items like an old T-shirt with your scent.

3. Natural Instinct

Dogs have an innate scavenging instinct, which may lead them to eat grass. While modern dogs don't need to hunt for their food, their wild ancestors relied on scavenging. Occasionally eating grass is usually not a problem and can even help prevent parasite infections. Interfering with this natural instinct might do more harm than good.

How to Discourage Your Dog from Eating Grass

While eating grass occasionally may not be harmful, there are potential risks to be aware of. Many lawns are treated with herbicides and pesticides, which can be toxic to dogs. Additionally, grass may contain intestinal parasites from other dogs' fecal matter.

To discourage your dog from eating grass, you can use treats as a reward for avoiding the behavior. When you take your dog for a walk, bring along their favorite treats. If you see them trying to nibble on grass, redirect their attention and offer them a treat instead.

If your dog is eating grass due to psychological stress, offering more affection and attention can help. Use positive reinforcement and reward them for good behavior.

When to Seek Professional Help

If your dog starts eating grass more frequently, it may be a sign of an underlying health issue. Watch out for symptoms such as vomiting, diarrhea, weight loss, loss of appetite, blood in stool, or lethargy. Additionally, be cautious if your dog has access to houseplants, as some can be toxic if ingested.

If you suspect your dog has consumed toxic plants, too much grass, or chemicals, contact your vet immediately. Your vet can conduct blood tests or physical exams to diagnose the underlying condition. If your dog appears to be in distress, keep them hydrated and let them fast for eight to twelve hours before gradually reintroducing food.

In summary, while eating grass is a common behavior in dogs, it may be a sign of something more serious. If your dog’s grass-eating habits change or you notice any concerning symptoms, it's best to consult your vet for professional advice.
