Why Do Dogs Eat Grass?

A dog's stomach is not designed to break down plants. Ingested grass is often excreted undigested or surrounded by mucus. Diarrhea or vomiting can also occur as a result of high consumption. However, a dog's occasional tendency to eat grass reflects a normal behavior of the four-legged friend.

But why do dogs eat grass? Which behaviors and symptoms pose dangers? And how should dog owners react if they suspect an illness?

Dogs eating grass: something quite common

Dogs are omnivores and occasionally dedicate themselves to blades of grass marked by other dogs. Researchers suspect that the behavior is due to an ancient instinct and serves to eliminate the markings.

Furthermore, it is possible that grass-eating is due to the behavior of their ancestors. They had to go on a tedious search for food and occasionally had to make do with consuming herbs and wild greens.

Another theory attributes dogs' grass-eating to boredom or a preference for the taste of grass blades. Some dogs are said to eat grass out of boredom during walks, while others consider the plants a welcome change in their diet.

Dogs learn grass consumption from their mothers. It could therefore also be a learned behavior. However, if the dog eats too much grass, this can cause the four-legged friend to vomit. Some dogs even refrain from chewing when eating grass. As a result, digestive problems and diarrhea can occur.

Dog owners worry at this moment. And indeed, in this case, a veterinarian should be consulted to examine the animal thoroughly. A tip: To have all important data available, dog owners should keep a diary of the frequency and consequences of grass consumption.

Dogs eat grass for many reasons

Concrete reasons for a dog eating grass have not yet been scientifically proven. However, the following triggers could exist:

Digestive problems: Bone remnants, hair, or other foreign bodies can cause stomach upset. To vomit, the dog eats grass. In this way, the disruptive factors leave the body. However, not every dog vomits after ingestion. Alternatively, foreign bodies can be excreted via feces. The blades of grass thereby perform a similar function to sauerkraut, which should be administered for stomach upset. The stomach and intestinal walls thus remain unharmed.
Intolerances: If the dog is sensitive to certain food components in its food, this can manifest itself as diarrhea or vomiting. In this case, many dogs show a tendency to increased grass consumption. If dog owners notice an intolerance, the food should be changed.
Nutrient deficiency: Grass contains water, proteins, carbohydrates, and minerals. If the dog is undersupplied, it will become a grass-eater to compensate for the deficiency. It should be noted that a nutrient deficiency is usually due to an incorrect diet. In this context, dog owners should use the age and activity of the four-legged friend as a basis for energy requirements.
Thirst: Grass has a high water content. Thirsty dogs consume grass to quench their thirst.
Stress: Stress can cause blood sugar levels to drop. Grass contains sugary components, so the dog instinctively begins to chew grass.
Boredom: Not every dog is content with the usual walk. If the dog gets bored, it may tend to eat grass or look for other activities.
Illnesses: Excessive grass consumption can also be interpreted as an indication of illnesses such as kidney weakness or liver weakness.

A calming effect

Stress can cause the dog to consume grass during walks. It should be noted that dogs can react sensitively to noise, hustle and bustle, and other dogs. Similar to chewing gum in humans, the furry friends can relax when consuming herbs and wild plants.

Furthermore, the four-legged friends are also said to increasingly eat grass to divert the behavior of other dogs. To reduce grass consumption, it may be worthwhile to avoid crowded parks or the walking route along the main road. Instead, a sensitive dog benefits from quiet environments.

Dog eating grass: When is it problematic?

Vomiting, diarrhea, constipation, or blood-stained feces: If the dog eats small amounts of grass, there is no cause for concern. However, if the dog suffers from gastrointestinal problems and at the same time eats noticeably a lot of grass, caution is advised. Blood in the feces or vomit should also be taken seriously.

In all cases, dog owners should immediately consult a veterinarian and have the pet examined. Because in addition to inflammation of the gastrointestinal tract, for example, an intestinal obstruction can occur.

A blade of grass protrudes from the anus? This should not be removed on its own. Anyone who pulls on a protruding blade of grass may injure the mucous membranes of the rectum or anus. A veterinarian, on the other hand, removes the blade without injuring the animal.

Observation of poisoning symptoms

Datura, Angel's Trumpet, Euphorbia, Bryony, Gorse, and many other plants often adorn public places such as parks and numerous gardens. Highly toxic and weakly toxic plants are differentiated.

If a dog ingests such a plant, poisoning can manifest itself through symptoms such as vomiting, restlessness, fever, excessive salivation, rapid breathing, or an increased heart rate.

In case of unusual behavior

Changed behaviors can indicate that an illness is present. Thus, frantic eating of grass, the consumption of grass and soil, and the refusal of dog food should lead pet owners to consult a veterinary practice.

Danger of lungworms

Lungworms use creatures like snails as intermediate hosts. If the dog eats the snail, the four-legged friends can become infected with the parasites. Young, curious dogs tend to eat snails directly.

Older dogs often ingest the parasites when snails settle on grass and the furry friends consume them. In the dog's intestine, the larvae then leave the intermediate host and migrate to the dog's lungs.

The adult worms lay eggs, from which larvae hatch. The larvae, in turn, attack the dog's lung tissue.

Dog eating grass: When and how to act

That the dog eats greens from time to time is no cause for concern. Vomiting after consumption is also considered normal, provided it occurs rarely. It is possible that the consumption serves the expulsion of foreign bodies in the dog and is instinctively used by it.

However, if the dog eats grass in large quantities and then vomits or reacts with diarrhea, an examination by a veterinarian should be carried out.

In addition, pesticides are used in gardens, parks, and even fields for pest control. If the dog has consumed contaminated grass blades, a veterinarian should be consulted immediately. On busy roads, pollutants from cars can also settle on the grass along the roadside.

In the veterinary practice, the doctor makes a diagnosis, which is followed by the individual therapy.
