Why Dogs Eat Grass – Causes, What It Means & When You Should Take Action

Fresh grass seems to be particularly tempting to dogs, especially in spring. Many dog owners therefore regularly ask themselves: Why do dogs eat grass? Is it a sign of stomach problems? A nutrient deficiency? Or simply normal behavior?

The good news upfront: In most cases, it is completely normal for dogs to eat grass. Nevertheless, the behavior can have different causes – from digestive problems to stress and even instinctive behavior.

Below you will find the most common reasons and when you should take a closer look.

One of the most common explanations for why dogs eat grass is gastrointestinal discomfort.

The tough blades of grass can tickle the throat and thus trigger a gag reflex. This makes it easier for dogs to vomit. Your dog may be trying to stimulate its digestive system or expel indigestible objects from the gastrointestinal tract.

If your dog regularly eats grass and vomits afterwards, you should take it seriously and seek veterinary advice. Especially if additional symptoms such as diarrhea, loss of appetite, or lethargy occur.

Another possible cause for dogs eating grass is an imbalance in their diet.

In addition to water, grass contains small amounts of vitamins and minerals such as calcium, magnesium, and iron. Some dogs may be trying to compensate for a lack of fiber.

The important question is therefore:
Does your dog receive complete food or only supplementary feed?

A balanced, nutritionally complete diet is the foundation for a healthy digestive system – and can reduce excessive grass eating.

In addition to vitamins and minerals, grass also contains water. Thirsty dogs therefore like to eat fresh, juicy grass during walks. On warmer and hot days, it is important to always have fresh water with you for your four-legged friend and offer it regularly.

It is not always due to a physical reason. Eating grass can also be a so-called displacement behavior.

• Is your dog bored?

• Is he overwhelmed or stressed?

• Is he in an unfamiliar situation?

Chewing can have a calming effect. In such cases, it helps to make walks more varied or to incorporate targeted training.

If your dog shows the behavior due to stress, you should identify the cause and help him to cope with the situation more calmly.

Puppies often observe their mother's behavior and adopt it. Furthermore, eating grass is an instinctive behavior that dates back to our dogs' ancestors.

Some experts believe that wolves consumed plant remains from the stomachs of their prey. Others suspect that it served to conceal their own scent.

In short: A certain amount of grass eating is evolutionarily determined and completely normal.

As a general rule: Grass itself is not toxic.

However, you should make sure that your dog does not eat grass that:

• has been treated with pesticides

• grows along heavily trafficked roads

• could be contaminated with pollutants

In addition, caution is advised if your dog eats unknown plants. Many plants are toxic to dogs.

Toxic plants for dogs (selection):

• Agave

• Snapdragon

• Wisteria

• Christmas star

• Ivy

• Golden rain

• Hydrangea

• Cherry laurel

• Lilies

• Oleander

• Rhododendron

• Tulips

If symptoms such as severe vomiting, diarrhea, abdominal cramps, lethargy, or unusually high thirst occur, you should seek immediate veterinary help.

Grass eating in dogs is in most cases harmless and natural. Nevertheless, it is worth taking a closer look:

• Does it regularly occur with vomiting?

• Does your dog show other symptoms?

• Is there possibly a nutrient deficiency?

• Could stress or boredom play a role?

In case of digestive problems or uncertainties, a veterinary examination is recommended. A review of the feeding can also be useful.

With a balanced diet, sufficient exercise and mental stimulation, the behavior can often be well understood and managed.
