Written by Adriana

It is a common problem for many dog owners, to find their dog chewing on grass and then inevitably throwing it up later! But why do dogs do this? In this article, we will look at the reasons behind your dog’s grass-eating habit.

Your dog may be chewing on the grass, but it’s not because he wants to eat it. It could be that your dog has a concern with his teeth or gums and needs some help. If you suspect this, then you need to take him to see an animal dentist as soon as possible.

The sooner you can get your dog checked out by a vet, the better chance there is of finding a solution to his issues. It is a common concern in dogs and if left untreated, it can lead to other health issues such as gum disease and tooth loss.

Why Is My Dog Eating Grass?

A dog that eats grass, or weeds for that matter, can cause a lot of problems for the owner and their family. The first thing to do when you notice your dog eating grass is to get it checked by a veterinarian.

Your vet will be able to tell if any underlying medical issues may be causing your dog to eat grass. If they find nothing wrong with your dog then they will try to figure out why your dog is doing this.

They might suggest that you change up his diet so he doesn’t have access to grass. Some dogs just like to chew on things and not necessarily food. This could also be the reason your dog is chewing on grass.

Dogs should not eat an excessive amount of grass. It can lead to stomach upset as well as other health issues such as worms. Dogs who eat too much grass can become very ill.

Reasons Why Your Dog is Suddenly Eating Grass

Reasons Why Your Dog is Suddenly Eating Grass

There are many reasons why a dog would start eating grass. Here are some of the most common ones:

  1. Boredom, stress, or anxiety – your dog may be bored, stressed, or anxious and needs to relieve these feelings by chewing on something. This happens when dogs are left alone for long periods. Dogs will eat grass when feeling boredom or stress because they have no other way of relieving their feelings. There are times when a dog just wants to play around. Sometimes they will choose to chew on something instead of playing. Chewing on grass is one way that a dog can entertain themselves while they are waiting for you to come home. Many dogs tend to eat more when they are anxious or stressed. When a dog is stressed, they often turn to eat something that makes them feel better. For example, if your dog is having trouble sleeping at night, he may decide to eat grass to calm himself down.
  1. It’s a natural behavior – dogs are naturally curious creatures and will often chew on things they find interesting. They also need to clean their teeth with their tongues, so it makes sense that they would chew on grass. This behavior can be seen in puppies as well as adult dogs. 
  2. He/she is looking for food – some dogs will eat grass if they are hungry or thirsty. If you see your dog eating grass, make sure he/she has eaten before you start worrying about him/her being sick. 
  3. They are looking for attention – this is the most common reason why dogs eat grass. When dogs feel neglected or lonely, they will look for ways to get attention from people. By chewing on grass, they are trying to get your attention. 
  4. They want to play – sometimes dogs just like to chew on stuff. Sometimes they do this out of boredom, but it could also mean they are playing. 
  5. They smell something – dogs love to smell everything around them. Some dogs will sniff at grass to figure out what kind of smells there are nearby. 
  6. Upset Stomach – if your dog eats grass after vomiting, then it means his stomach is upset. Make sure he gets plenty of water and rest. This is a common sign of an upset stomach and means nothing serious. Sometimes a dog will eat grass simply because they are feeling unwell. If your dog has diarrhea, he may think that grass is helping him to cleanse his system. 
  7. They are thirsty – if your dog chews on the grass while drinking, then he/she is probably thirsty. You should offer him/her some water. 
  8. It’s a habit – if your dog always chews on grass, then he might be doing it because it’s a habit. Try to break this bad habit by making sure your dog doesn’t have access to grass often, or that they are supervised. 
  9. Dietary Response – if your dog suddenly starts eating grass, then this could be due to dietary response. It means that your dog isn’t getting enough nutrients in his/her diet. Talk to your vet about adding more vitamins and minerals to your dog’s diet. 
  10. Digestive Issues – if your dog seems to be having digestive issues, such as diarrhea, then he/she may be chewing on the grass to try to help ease the pain. 
  11. They are lonely – Another reason why a dog may start eating grass is that they are lonely. If your dog lives alone all day long, he may want to spend time with another animal. Since he does not have anyone else to interact with, he may start eating the grass to make himself feel better. 
  12. He has a sensitive tummy – Sometimes dogs have sensitive tummies, and they don’t know how to properly deal with certain foods. In these cases, they will try to avoid anything that makes them uncomfortable. If your dog has a sensitive tummy, he may start eating grass because it feels good to him. 
  13. He has been fed a high-protein diet – A high-protein diet means that your dog gets more than 20% of his calories from meat. When a dog starts getting more than 20% of its daily calorie intake from meat, it becomes harder for them to digest carbohydrates. This causes them to crave more protein which leads to them eating grass. 
  14. Other – if none of the above reasons apply to your dog, then maybe he/she is just curious about grass. Don’t worry too much about it unless your dog continues to eat grass frequently.

Should Dogs Eat Grass?

Should Dogs Eat Grass

Dogs should not eat grass. There are many health risks associated with consuming grass. Not only does it cause gastrointestinal problems, but it can also lead to heart disease, liver damage, kidney failure, and even cancer.

If your dog consumes grass, it can cause:

  1. Gastrointestinal Problems – The main concern with eating grass is that it causes gastrointestinal issues. Eating grass can cause an upset stomach, diarrhea, constipation, gas, nausea, vomiting, bloating, and weight loss. These symptoms usually go away within 24 hours. However, if your dog keeps eating grass, these symptoms can become worse over time. 
  2. Heart Disease – Grass contains high levels of oxalate which can cause calcium oxalate crystals to form in the kidneys. Over time, these crystals can block the blood vessels in the kidneys, causing chronic kidney disease. 
  3. Liver Damage – Oxalates can also enter the bloodstream and travel through the body where they can cause inflammation and damage to the liver. If left untreated, this can result in cirrhosis of the liver. 
  4. Kidney Failure – Oxalates can cause stones to form in the urinary tract. Stones can obstruct the flow of urine and cause kidney failure. 
  5. Cancer – Oxalates can stimulate the growth of certain types of tumors. Studies show that people who consume large amounts of oxalic acid (grass) have higher rates of bladder cancer than those who do not. 
  6. Weight Loss – Grass has been shown to contain substances that make you feel full, so when dogs chew on it, they don’t get hungry again until long after they’ve eaten all the grass. This leads to them losing weight. 
  7. Hair Loss – Grass contains chemicals called phytoestrogens that can affect hair follicles. When this happens, the hairs will fall out or grow sparsely. 
  8. Skin Rash – Grass can irritate the skin and cause rashes. 
  9. Allergies – Grass contains proteins called lignins that can trigger allergies.

How Can I Prevent My Dog From Chewing On Grass?


There are several ways that you can prevent your dog from eating grass. You can use a product like “Grass-Off” to keep your dog from eating grass, or you can simply remove the grass from your yard.

”Grass-Off” is a product that works by coating the grass blades with a sticky substance. Once the grass is coated with the material, your dog won’t want to eat it anymore.

It’s important to note that “Grass-Off” doesn’t work for every type of grass. For example, it won’t help your dog stop chewing on Bermuda grass.

Here are some more tips to prevent your dog from eating grass:

  1. Keep Your Grass Short – If your grass is tall, your dog won’t be able to reach it easily. Make sure that your lawn is short enough for your dog to play in safely. 
  2. Cut It Off – If your dog starts to eat grass, cut off the grass right away. Do not allow him to continue chewing on it. 
  3. Train Your Dog To Avoid Grass – Teach your dog to avoid grass by rewarding him whenever he doesn’t touch it. Use treats like peanut butter or cheese as rewards. 
  4. Remove Grass From Your Yard – If your dog continues to eat grass even after you’ve tried everything else, then you may need to take action. Contact a professional landscaper to trim your grass and remove any weeds.

Why is My Dog Being Sick After Eating Grass?

Why is My Dog Being Sick After Eating Grass

If your dog eats too much grass, he could develop an upset stomach. He might vomit, throw up, or experience diarrhea. These symptoms are usually caused by the toxins found in grass.

The most common symptom of poisoning is vomiting. Other signs include diarrhea, excessive salivation, muscle tremors, weakness, seizures, and coma. Dogs who ingest grass often become lethargic and lose their appetite.

They may also try to lick off the grass because they’re trying to clean themselves.

What Should I Do If My Dog Has Been Poisoned By Grass?

The first thing that you should do if your dog has ingested grass is to call your veterinarian immediately. Your vet will give your dog fluids and medication to treat his illness.

He will also recommend that you contact poison control services to find out how to properly dispose of the grass.

What Should I Do If My Dog Has Already Eaten Grass?

If your dog has already started to eat grass, there are things that you can try to help him recover. The first thing that you should do is to give him water. Water helps flush the toxins from his system.

After giving him plenty of water, you can offer him something sweet to drink. Sugar is an effective way to reduce the number of oxalates that he ingests.

You can also put some ice cubes in a bowl of warm water and let him lick them. Licking cold ice cubes reduces the temperature of the tongue and makes it less likely that he’ll swallow the oxalates.

If these methods fail, you may need to contact a veterinarian. They can perform tests to determine what exactly is causing your dog’s illness.


Your dog needs to eat healthy food. However, sometimes dogs get into trouble when they eat grass. This article discusses why this happens, what causes it, and what you can do about it.

Hopefully, you now have a better understanding of why your dog is eating grass and what you can do to stop him from doing so.
