How Grass Acts As A Dog Laxative

Dogs eating grass is a common sight, and many theories attempt to explain this behaviour. One popular belief is that grass acts as a laxative for dogs, helping to move stool and relieve constipation. While there is limited research on why dogs eat grass, it is known that they cannot digest it, and it usually passes through their intestinal tract undigested. Grass may be dangerous for dogs to consume due to the presence of environmental toxins, parasites, bacteria, and viruses on it. If you notice your dog eating grass, it is important to monitor them for any signs of illness and ensure they do not ingest anything harmful.

Grass may serve as a laxative for dogs

It is speculated that grass may act as a laxative for dogs, aiding in moving stool along for constipated dogs. While there is limited research on why dogs eat grass, it is believed that it may be an instinctive behaviour that dogs have evolved from their wolf ancestors. Wild canids, including wolves, jackals, foxes, and coyotes, have been observed to eat grass.

Eating grass may be a way for dogs to supplement a missing nutrient or fibre in their diet. In one case, an 11-year-old Miniature Poodle with a history of eating grass and plants stopped this behaviour once placed on a commercial high-fibre diet. This suggests that the dog was trying to address a dietary deficiency by consuming grass and plants.

However, it is important to note that dogs primarily cannot digest grass, as it passes through their intestinal tract undigested. Additionally, grass-eating can be dangerous for dogs as it may be contaminated with pesticides, insecticides, parasites, bacteria, viruses, or other toxins. A significant amount of grass consumed could also get stuck in a dog's intestinal tract, causing an obstruction.

If you notice your dog eating grass, it is recommended to interrupt the behaviour calmly and reinforce alternate behaviours. It is also crucial to ensure your dog has access to grass that is free from toxins and other harmful substances.

While grass may serve as a natural laxative for dogs, it is always recommended to consult a veterinarian before giving your dog any type of laxative, including natural ones. Veterinarians can advise on the proper dosage and type of laxative suitable for your dog's size and age. They can also help determine if there is an underlying cause for your dog's constipation that needs to be addressed.

Dogs should not be given human laxatives

While there are laxatives specifically labelled for dogs, you should never give your dog human laxatives without first consulting your vet. Human laxatives can cause severe symptoms when given to dogs, leading to serious or even fatal complications.

Human and dog laxatives may contain similar ingredients, but they are given at different doses. There is a danger of overdosing a dog by giving them a human laxative without discussing it with a veterinarian. For example, Dulcolax® is a well-known human laxative brand that contains the active ingredient bisacodyl. Most veterinarians will recommend this for home use for the temporary relief of constipation in dogs. However, if your dog has an allergy or sensitivity to this drug, it should not be used. Dogs with gastrointestinal tract obstructions, tears in their intestinal walls, or rectal bleeding should also avoid this drug.

If your dog is experiencing constipation, there are some home remedies you can try to help alleviate their discomfort. Firstly, ensure they have access to fresh water and are drinking plenty of it throughout the day. You can also add supplements to their diet, such as canned dog food, to increase their moisture and liquid intake. Natural fibres, such as pumpkin puree or wheat bran, can also help move things along. However, if your dog has been constipated for two days or longer, you should schedule an appointment with your vet right away. Chronic constipation can quickly turn into an emergency situation that causes dehydration, decreased appetite, weight loss, vomiting, severe pain, infection, and more.

Laxatives can be dangerous for dogs

While laxatives can be a good way to treat constipation in dogs, they can also be dangerous. If you suspect your dog is constipated, it is important to consult a veterinarian before giving them any medication. There are other conditions that can mimic constipation, and giving a laxative for these conditions can have negative consequences. Additionally, human laxatives can be dangerous to administer to dogs.

Different doses for dogs and humans

According to Dr. Leilani Im, manager for the San Diego Humane Society, humans and dogs use similar laxatives but at different doses. Therefore, there is a danger of overdosing a dog by giving them a human laxative without discussing it with a veterinarian.

Laxatives can cause dehydration

Laxatives work by inhibiting water absorption in the colon, which can result in dehydration. Dehydration can cause constipation, so it is essential to make sure your dog is well-hydrated before offering a laxative.

Laxatives can cause diarrhea

Depending on the dose and product, your dog could end up with diarrhea after taking a laxative. Diarrhea can be dangerous for dogs, leading to dehydration and other health issues.

Laxatives can mask underlying issues

If your dog is constipated, there may be an underlying issue such as a poor diet, insufficient exercise, or a more serious condition. Giving your dog a laxative without addressing the underlying issue may provide temporary relief but could make the problem worse in the long run.

Laxatives can be habit-forming

Long-term use of laxatives can be dangerous for dogs, as it can lead to dependency and cause health issues such as dehydration and electrolyte imbalances.

In conclusion, while laxatives can be an effective treatment for constipation in dogs, they should only be given under the supervision of a veterinarian. There are also natural remedies for dog constipation, such as increasing your dog's water and fiber intake, that may be effective in mild cases.

Natural laxatives are available for dogs

There are several natural options that may assist with the symptoms of dog constipation. These include:

• Pumpkin Puree: Pumpkin is high in fibre and moisture, which helps regulate the digestive tract. It is recommended to feed dogs one to two tablespoons of pureed pumpkin—not pumpkin pie filling, which could contain spices and sweeteners—once or twice a day.
• Mineral Oil: Although considered "old school" by some veterinarians, mineral oil can be applied around the dog's rectum to help them pass stool.
• Psyllium: A soluble fibre that has a laxative effect in dogs. It is recommended to mix one to two tablespoons of wheat bran or one to four teaspoons of Metamucil (a psyllium product) into a dog's food up to two times per day.
• Probiotics: Probiotics can help promote beneficial gut bacteria and prevent constipation. However, they should be administered with caution to dogs with compromised immune systems.
• Coconut Oil: Coconut oil can be used as a stool softener and lubricant for the interstitial tract.
• Olive Oil: Olive oil can help soften stools and lubricate the interstitial tract, making it easier for dogs to pass stool. However, it should not be given frequently, as it can cause diarrhoea.
• Bran: Bran can be added to a dog's food regularly to help prevent constipation.
• Powdered Psyllium Seed: Psyllium seed powder pulls water into the stool to help move it along.
• Aloe Ferox: Aloe Ferox has a beneficial effect on digestive functioning and acts as a natural system cleanser.
• Increased Exercise: Exercise will massage internal organs and increase blood flow in the colon, promoting normal movement within the gastrointestinal tract.

In addition to these natural laxatives, it is important to ensure that dogs are properly hydrated and are consuming enough fibre and water.

Consult a vet before giving dogs laxatives

While there are laxatives specifically designed for dogs, you should never give your dog human laxatives without first consulting a vet. Laxatives for humans can cause severe symptoms in dogs, which can lead to serious or even fatal complications.

Always consult a licensed veterinarian before giving any medications to your dog, including over-the-counter medications such as laxatives. Your veterinarian will be able to advise you on the correct dog laxative for your dog's specific case. They will also be able to advise on the correct dosage for your dog's size and age.

If your dog has been constipated for two days or longer, or is straining or crying out when trying to defecate, schedule an appointment with your vet right away. Chronic constipation can quickly turn into an emergency situation, causing dehydration, decreased appetite, weight loss, vomiting, severe pain, infection, and more.

If you have already given your dog a human laxative, don't panic, but do call a vet or the Pet Poison Helpline. Make sure you have the following information to hand when you call:

• The name of the medication
• The strength of the medication (listed on the container)
• The amount you gave your dog
• The time you gave the medication to your dog
• Any symptoms your dog is experiencing

Also, bring the medication container with you to the veterinary hospital.

There are several different kinds of laxatives, and each type has a different physiological effect on the body. The five main types of laxatives are: bulk-forming, lubricant, emollient, osmotic, and stimulant. Bulk-forming laxatives, for example, are dietary fibre supplements that absorb water, soften faeces, increase mass, and naturally stimulate the colonic smooth muscle, making it easier for your dog to pass excrement. Lubricating laxatives such as mineral oil and white petroleum make faecal transit easier but are only useful in situations of minor constipation. Emollient laxatives such as docusate sodium and docusate calcium increase the amount of water the stool can absorb within the gastrointestinal tract. Osmotic laxatives pull water from surrounding tissues into the intestines, creating excess moisture in the intestine, resulting in softer stools that are easier to pass. Finally, stimulants trigger the contraction of the intestinal muscles to create a bowel movement. This is a more serious approach and should only be used under close veterinary supervision.
