Dogs eating grass is a common phenomenon that has puzzled many pet owners. Some dogs eat grass regularly, while others only do it occasionally.

Research suggests that dogs may eat grass for a variety of reasons, including boredom and stress relief.

In fact, a study found that dogs that eat grass tend to have higher levels of stress hormones in their system.

Many dogs will eat grass in the spring and summer months when they are feeling particularly energetic and playful.

Why Do Dogs Eat Grass?

Dogs eat grass for a variety of reasons, but the exact reason is still unknown.

Some theories suggest that dogs eat grass when they need to vomit, but this is not a common occurrence, affecting fewer than a quarter of dogs that eat grass.

Dogs are omnivores, which means they can eat both meat and plants. In fact, wild dogs include plants in their diet, and may even ingest them secondarily by consuming the stomachs of their herbivorous prey.

Grass does contain some essential nutrients, but even dogs with a balanced diet will sometimes eat grass.

Eating grass may be a way for domesticated dogs to make up for the plants that are missing in their kibble, since wild dogs would naturally eat a variety of plants in their diet.

Health Risks and Symptoms

Dogs eating grass is a common phenomenon, but what are the potential health risks and symptoms?

Only 8% of dog owners reported seeing signs of illness before their dog ate grass, and of that group, only 22% reported that their pups actually vomited after doing so.

There is no consistent link between illness and eating grass, and research doesn't support the theory that dogs eat grass because they're sick.

A study found that a healthy dog was actually more likely to eat grass than one with diarrhea.

Diarrhea wasn't a motivator for dogs to eat grass, according to this study.

If your dog is vomiting frequently or has other signs of illness, they need to be evaluated by a vet right away.

Bilious vomiting syndrome is a possible cause of vomiting in dogs, especially if they're eating grass early in the day before a meal.

This condition causes vomiting when the stomach is empty for too long.

Is Normal Behavior?

For most dogs, eating grass is a normal behavior that's been passed down from their wild ancestors. In fact, studies show that 11-47% of wolves eat grass, and it's likely that dogs do the same for similar reasons.

Some dogs may eat grass to pass the time or to aid in digestion, while others might just enjoy the taste. Whatever the reason, it's clear that grass-eating is a natural behavior for dogs.

If your pup likes to graze now and then, it's probably harmless, and you can allow it. But if they're consistently eating grass every time they step outside, it's worth investigating further.

Eating grass may provide dogs with a source of fiber, which has many health benefits, such as preventing constipation and increasing feelings of fullness without added calories.

What Causes?

Dogs eat grass for a variety of reasons, and it's not always a simple explanation. There are numerous theories, but no concrete evidence to prove them.

Some dogs may eat grass due to a psychological need, as it can be a way to self-soothe and settle boredom. Many domesticated dogs live an anxious life, struggling with separation anxiety or specific anxiety triggers.

A diet deficiency could also be a reason why dogs eat grass. This condition is sometimes caused by a diet lacking essential vitamins, nutrients, or minerals.

Dogs who are fed a well-balanced diet shouldn't experience this issue, so it's worth considering a change in dog food if your dog repeatedly eats grass.

Gardening and Safety

Gardening and Safety is a top concern for dog owners who let their pets graze on grass. Garden organically, for the sake of both the planet and your dogs.

Growing your own organic garden is a great way to create a safe space for your dogs to explore. Using natural and non-toxic methods to control pests and diseases is a key part of organic gardening.

By gardening organically, you can minimize the risk of your dogs ingesting toxic substances that might be present in conventional gardening products.

By taking a few simple precautions and choosing dog-friendly plants, you can enjoy the benefits of gardening while keeping your furry friends safe.

Beware of Rough

Long, rigid grasses with sharp edges can cause throat abrasions in dogs.

Dogs who eat this type of grass can experience intestinal blockages, which is a serious medical issue.

If your dog is coughing, vomiting, not eating, or showing signs of irritation after eating these kinds of grasses, contact your veterinarian immediately.

This type of grass can be found in many lawns and gardens, so it's essential to be aware of its potential dangers.

What to Do

If your dog is eating grass, it's essential to identify the underlying cause, as it could be a sign of a gastrointestinal issue or an attempt to self-medicate. Many dogs eat grass due to a nutrient deficiency, such as a lack of fiber.

Some dogs may eat grass due to boredom or anxiety. According to research, dogs that eat grass are more likely to be anxious or stressed.

If you suspect your dog is eating grass due to a gastrointestinal issue, try a bland diet for a few days to see if symptoms improve. A bland diet consists of boiled chicken and rice.

Monitoring your dog's stool quality and overall health is crucial to determine if the issue is resolved. Regular check-ups with your veterinarian will also help identify any underlying health issues.

In some cases, eating grass may be a sign of a more serious health issue, such as gastrointestinal foreign bodies or gastrointestinal disease.

Pica and Illness

In some cases, eating grass may be a sign of pica, a desire to eat non-food items. Pica is a well-recognized phenomenon, but its causes are still not fully understood.

Dietary deficiency is one possible explanation for pica in dogs. However, research suggests that only a small percentage of dogs eat grass due to illness.

Some experts believe that pica may be linked to nutritional deficiencies or parasite treatment. In fact, one study found that only 25% of dogs regularly vomit after eating grass, which suggests that grass may not be a natural purgative after all.

Here are some possible explanations for pica in dogs:

  • Dietary deficiency - to correct a nutritional deficiency in the diet
  • Anti-parasite treatment - to purge worms or larvae from the stomach
  • Exploratory behavior - in a similar way puppies chew anything and everything
  • Learned behavior - it becomes a habit
  • Hunger - puppies especially will exhibit pica if they are underfed
  • Stress - the repetitive action of chewing is soothing to some dogs

It's worth noting that seeing your dog eat a few servings of grass occasionally is not a cause for concern. However, if your companion seems to be looking for grass to eat at every opportunity, a veterinarian check-up with a stool analysis may be in order.

Possible Illness

Eating grass is not a consistent sign of sickness, with only 8% of respondents reporting seeing signs of illness before their dog ate grass.

In fact, one study found that a healthy dog was actually more likely to eat grass than one with diarrhea.

Research suggests that only around 25% of dogs regularly vomit after eating grass, which contradicts the idea that grass is a natural purgative.

While some dogs may have learned to associate eating grass with solving digestive problems, there's no scientific evidence to support this theory.

If your dog is eating grass at every opportunity, it's worth taking them to the vet for a check-up with a stool analysis.

May Be Pica

Pica can manifest in various ways, including eating grass. Some dogs may crave unusual substances, just like pregnant women may have strong cravings for certain foods.

Pica is a recognized phenomenon with no clear explanation for its cause. It's possible that a dog's diet is lacking in essential nutrients, leading them to eat non-food items to correct the deficiency.

Dogs may also exhibit pica as a result of anti-parasite treatment, which can cause them to purge worms or larvae from their stomach. Exploratory behavior is another potential cause, similar to how puppies often chew on anything and everything.

In some cases, pica can be a learned behavior, where a dog develops a habit of eating non-food items. Hunger can also be a contributing factor, especially in underfed puppies.

The repetitive action of chewing can be soothing for some dogs, which may explain why they engage in pica as a coping mechanism for stress.
