Have you ever spotted your beloved canine companion nibbling on the lush green blades in the backyard and found yourself pondering the reason behind this seemingly peculiar behaviour? This intriguing habit has fascinated pet owners and experts for generations. In this blog, we will explore the various factors that might drive your furry friend to indulge in this grassy feast, unfolding the mystery behind their seemingly strange dietary preferences and habits.

Why do dogs eat grass?

Dogs have been known to display a liking towards occasionally nibbling on grass. While the exact rationale may differ from one dog to another, several theories attempt to shed light on this behaviour, providing explanations for this habit. Understanding the underlying motivations can provide valuable insights into our furry friends’ dietary preferences. Your dog could be eating grass due to various causes, some of which are listed below.

  • They like it

Some dogs simply relish the taste and texture of grass, which might be due to the change in taste, texture, or smell during different seasons. For them, indulging in a bit of greenery might be akin to us savouring a favourite snack. It may not necessarily serve any particular purpose other than fulfilling a canine craving for something different and intriguing, making it a harmless pastime that satisfies their curious taste buds and offers them a brief moment of sensory delight amid their daily routines.

  • They are bored

In certain instances, dogs may resort to grass as a means of alleviating boredom and seeking sensory stimulation. Particularly for those lacking sufficient mental or physical engagement, exploring the various textures and tastes of the outdoors can serve as a form of entertainment, helping to pass the time and provide a temporary distraction from their otherwise monotonous routines. This act of grazing on grass could serve as a form of mental enrichment, offering them a much-needed change of pace and an opportunity to engage their senses.

  • They need fiber

Dogs, like humans, require a certain amount of fibre in their diets to maintain a healthy digestive system. Since grass is a natural source of fibre, sometimes dogs can eat grass instinctively to aid in digestion, especially if their regular diet lacks adequate fibre content. This act of consuming grass could potentially help them regulate their digestive processes, promoting better overall gut health and ensuring smooth bowel movements, contributing to their overall well-being and physical comfort.

  •  It helps them fight parasites

Surprisingly, grass contains certain properties that could aid dogs in purging their system of any potentially harmful intestinal parasites. By inducing vomiting through grass consumption, dogs might instinctively attempt to cleanse their digestive tract, ridding themselves of any unwelcome parasites that could be causing discomfort or distress. This natural mechanism could be a part of their innate self-care routine, serving as a means of maintaining their overall health and well-being while safeguarding them from potential health risks posed by internal parasites.

Pay attention to your dogs' grass-eating habits 

Keeping a close eye on your dog's grass-eating habits is essential for understanding their overall well-being. Despite common assumptions, the act of consuming grass does not necessarily indicate an underlying illness, with reports suggesting that only about 10% of dogs appear to be unwell before indulging in grass. This emphasises the importance of paying attention to other cues to gauge your pet's health accurately and understand if grass is good for dogs.

Furthermore, it is worth noting that most dogs, approximately 25%, who consume grass do not end up vomiting regularly after grazing. This challenges the conventional notion that grass consumption leads to subsequent vomiting. Some experts propose that this behaviour might aid in digestion or cater to specific nutritional requirements, such as the need for additional dietary fibre, indicating a potentially intuitive dietary mechanism in canines.

However, as mentioned previously, it is plausible that your dog simply relishes the taste or texture of grass, viewing it as a form of sensory stimulation. By closely observing your dog's grass-eating patterns and any accompanying behaviours, you can discern whether this habit is a matter of preference or indicative of underlying health issues that require attention. This vigilance allows for a comprehensive understanding of your pet's dietary preferences and potential nutritional needs.

Know whether you should stop them from eating grass, and if so, how?

If you suspect your dog is eating grass out of boredom, it is crucial to ensure it is getting sufficient exercise and mental stimulation. Consider incorporating engaging activities into its routine, such as playing interactive games like fetch or providing it with durable chew toys to keep it occupied and mentally stimulated.

In cases where your dog's grass-eating behaviour stems from a potential nutritional deficiency, transitioning to a higher-quality dog food, particularly one rich in dietary fibre, could help address the underlying issue. Consulting with a veterinarian to determine the most suitable dietary adjustments for your dog is advisable to ensure it receives the necessary nutrients.

While most experts agree that grass consumption itself isn't harmful, it's important to remain mindful of potential hazards. Some lawn treatments, including herbicides and pesticides, can be toxic if ingested. Similarly, several common household and garden plants are toxic to dogs, leading to health complications if consumed alongside grass. Being vigilant about the types of plants and substances your dog has access to will significantly mitigate potential risks associated with their grass-eating behaviour.

    How much do you know about the food you’re buying for your puppy? When shopping for puppy food, pay attention to these three sections of a dog food label.


    1. The Ingredient Panel

    This section lists all the ingredients that make up the product. The ingredients are listed in descending order according to weight before cooking. In dry food, look for a source of high-quality animal-based protein: chicken or lamb, for example. Dogs thrive on animal proteins.

    Manufacturers who use large amounts of vegetable proteins might be saving money by providing basic — but not optimal — nutrition. You should also avoid artificial colors and flavors, which offer no nutritional benefits.


    2. The Guaranteed Analysis

    Near the ingredient panel should be a chart of percentages called the 'guaranteed analysis.' These figures reveal the basic nutrient makeup of the dog food's formula and protein content. The minimum percentages of protein and fat and the maximum percentages of fiber and moisture (water) should be listed.


    3. The Manufacturer’s Name and Address

    This information must be included on the label by law. A toll-free number or web address for the manufacturer may also be listed. Manufacturers who list a phone number, such as IAMS™, generally have a high-quality product and welcome consumer calls and questions. If you would like information about IAMS products, visit our website or call us toll-free at 800-525-4267.
