If you've ever watched your dog happily munching away on the lawn, you've probably wondered why they do it. Is it to settle their stomach, because they enjoy the taste or because they're looking for something missing from their diet?
There are a few possible reasons dogs eat grass, and understanding their behaviour can help you work out what's going on with your own dog.
1. Dogs May Eat Grass When They Have an Upset Stomach
Some dogs eat grass when they're experiencing digestive discomfort, nausea or bloating. They may eat larger amounts than usual and sometimes vomit afterwards.
Possible reasons include:
-
Gastrointestinal upset
-
Nausea or digestive discomfort
-
Gas or bloating
-
Eating something that doesn't agree with them
-
An underlying illness
However, not every dog that eats grass is trying to make themselves vomit. Research suggests that vomiting isn't the usual outcome of grass eating, and many dogs eat grass without showing any signs of illness beforehand.
If your dog regularly vomits after eating grass, it's worth looking more closely at their diet and digestive health rather than assuming it's simply a natural way to clear their system.
2. Dogs May Simply Enjoy Eating Grass
Sometimes, there's no obvious problem at all. Your dog may just enjoy the taste, texture or experience of eating grass.
You might notice them carefully selecting particular grasses, nibbling with their front teeth and moving from one patch to another. Others may graze while exploring the garden or during a walk.
Boredom may also play a part for some dogs, particularly if grass eating becomes a repetitive activity when they're looking for something to do.
Occasional grass eating, without other changes in behaviour or health, is generally a normal canine behaviour.
3. Dogs May Be Seeking Fibre or Other Plant Nutrients
Grass contains fibre and plant compounds, and eating vegetation is a behaviour seen in many dogs.
It's possible that a dog's interest in grass is influenced by its texture, taste or digestive effects. However, we can't assume that a dog is deliberately seeking a particular vitamin, mineral or enzyme simply because they're eating grass.
If your dog frequently seeks out grass, it's worth reviewing their diet. A varied, fresh-food diet can help provide the fibre and nutrients dogs need, alongside suitable sources of protein and essential fats.
Should You Let Your Dog Eat Grass?
In many cases, occasional grass eating isn't something you need to prevent. However, be mindful of where your dog grazes.
Avoid grass that may have been treated with pesticides, herbicides or other chemicals. Also, make sure the area doesn't contain toxic plants or other substances your dog could ingest.
It's also worth paying attention to changes in the way your dog eats grass. Suddenly eating large amounts, repeatedly vomiting or showing signs of abdominal discomfort is different from casually nibbling a few blades on a walk.
What If Your Dog Eats Grass Frequently?
If your dog is constantly eating grass, particularly alongside vomiting, changes in appetite or digestive discomfort, take a closer look at their diet and overall wellbeing.
Even a premium or expensive food that your dog has eaten for years may not suit them as well as you'd expect. Their needs can change over time, and the overall composition and digestibility of their diet matter.
If your dog regularly vomits after eating grass, or vomits weekly or more often, don't dismiss it as normal. Repeated vomiting deserves investigation rather than simply changing foods and hoping the problem resolves.
Consider whether your dog's diet provides appropriate protein, essential fats, fibre and other nutrients. Their food should also suit their individual digestive needs.
Supporting Your Dog's Digestive HealthÂ
If your dog is a frequent grass eater, these are some natural feeding and digestive support options to consider.
-
Review their diet. Moving towards a suitable fresh-food diet can help you take a closer look at the ingredients your dog is eating and how well their food suits them.
-
Consider digestive support. Synbiotic 180-S Probiotic Enzymes combines probiotics and digestive enzymes to support digestive function and a healthy intestinal environment.
-
Explore complementary digestive support. HomeoPet Digestive Plus is a homeopathic product intended to support digestive function.
- Herbal Digestive support. Digyton drops are a natural support to aid digestive upsets.
The right approach depends on what's driving your dog's behaviour. Grass eating alone doesn't necessarily mean something is missing from their diet, but frequent grass eating alongside digestive symptoms is a good reason to take a closer look.
Ultimately, knowing your dog's normal habits makes it easier to recognise when something changes and when their diet or digestive health may need some extra attention.
