Alternatives to Prevent Dogs From Eating Grass

The sight of your furry friend grazing on your lawn may have you questioning if they’re part canine, part cow. This eating behavior, often perplexing to dog owners, is surprisingly common and usually harmless, unless the grass is chemically treated. Nevertheless, if you want to curtail this lawn dining, there are several alternatives to consider.

Why Do Dogs Eat Grass?

Before diving into the alternatives, understanding why dogs eat grass is crucial. While the precise reason remains elusive, several theories have been proposed, including:

  • Instinctive Behavior: Some suggest that it’s a throwback to their wild ancestors, who consumed grass as part of their prey.
  • Nutritional Deficiencies: Dogs might be trying to compensate for a lack of fiber or certain nutrients in their diet.
  • Stomach Upset: Dogs might eat grass to induce vomiting and provide relief from gastrointestinal discomfort.

However, if grass-eating is paired with other symptoms like vomiting or lethargy, it’s advisable to contact a vet immediately.

Nutritious Alternatives to Grass

1. High-Fiber Foods

If your dog’s grass consumption is driven by dietary deficiency, introducing high-fiber foods can satiate this need. Consider incorporating fibrous vegetables such as carrots, green beans, or sweet potatoes into their meals. Alternatively, fiber-rich commercial dog foods are available in the market.

2. Fresh Herbs

Certain herbs can be a healthy and flavorful substitute for grass. For instance, parsley can freshen a dog’s breath, while rosemary can enhance their coat. Always ensure that the herbs you introduce are non-toxic to dogs.

3. Cat Grass

Cat grass (wheatgrass) is another suitable alternative. It’s safe for dogs and provides a great source of nutrition. Ensure it’s grown organically to avoid any chemical contamination.

Behavioral Interventions

4. Engage in Training

Training your dog to avoid eating grass can be effective. Use positive reinforcement techniques like treats and praise to reward your pup when they resist the urge to munch on grass during walks or playtime.

5. Increase Exercise

Boredom may lead dogs to eat grass. Regular exercise can combat this, stimulating their mind and helping them burn off energy. Consider games, puzzle toys, or interactive play sessions to keep them engaged.

6. Scheduled Feeding Times

Irregular feeding times may also lead to grass eating. Establishing a consistent feeding schedule ensures that your dog is not hungry and less likely to look for extra snacks in the yard.

When to Contact a Vet

Monitor your dog’s behavior carefully. If their grass-eating habit is coupled with frequent vomiting, weight loss, reduced appetite, or other unusual behavior, consult your vet immediately.


While grass eating is typically harmless for dogs, if it’s a cause for concern, there are several viable alternatives. Implementing a diet high in fiber, engaging in consistent exercise and training, or introducing safe and beneficial herbs can keep your pet from grazing in your garden. It’s always important to keep an eye on your dog’s habits and consult with your vet if you observe any concerning changes.

Always use repellents under the guidance of a vet or a professional dog trainer.
