Important Facts About Liver Disease in Dogs

Liver problems are a pretty common issue for dogs, so it is wise as a dog owner to understand what to look for and how to keep your dog’s liver function healthy. Sometimes it is even necessary to take proactive measures to protect some dogs’ livers. This post will explain everything about liver disease in dogs, including how CBD Oil can help.

What a Dog’s Liver Does

While not spoken about much, the liver is the largest organ of a dog’s body after their skin and it is incredibly important in helping their body function normally. It performs more than 1,000 crucial bodily functions impacting the blood clotting, nutrient management, toxin elimination, hormones, metabolism, and more.

Poor liver health is also much more common than most dog owners realize. Liver disease in dogs is one of the top five causes of non-accidental death in dogs of any age and one of the top four causes of death in older dogs.

Where is A Dog’s Liver Located

It’s natural to wonder this when thinking about the liver and potential problems with it. A dog’s liver is located in the center of the abdomen between their lungs and stomach. Kind of like the center of the dog’s belly, working toward the front half of the dog.

Liver Problems in Dogs

There are many liver disorders that can go wrong with a dog; acute liver failure, infectious canine hepatitis, endocrine diseases, liver cancer and many more. Most occur later in the dog’s life, but some can occur at any time and some occur at birth.

In this post, we’ll discuss most of the causes as well as the symptoms and treatment options for them.

What is Liver Damage in Dogs?

The liver becomes damaged before it becomes diseased, similar to how gingivitis left untreated becomes periodontal disease.

The problem is that liver damage has vague symptoms and an underlying cause that doesn’t seem obviously connected to the liver. Blood tests and testing liver tissue are needed for a definitive diagnosis of the most common liver disorders.

Symptoms of liver damage in dogs include:
  • loss of appetite
  • diarrhea
  • unexplained weight loss
  • darker urine
  • poor coat quality
  • hair loss
  • brittle, weakened, or infected nails
  • weakness
  • fatigue
  • irritability and/or aggression
  • generally seeming unwell

As you can see, most pet parents would get concerned about their dog when displaying these symptoms, but we probably wouldn’t think about their liver unless we knew to do so.

It is very important to be aware of this potential because catching liver damage before liver failure occurs in dogs makes a tremendous difference in the chances of recovery.

Investigate these symptoms to determine their cause, and be proactive about your dog’s liver health before they show these symptoms or as soon as you notice the symptoms.

What is Liver Disease and Chronic Liver Disease in Dogs?

Liver disease in dogs can be an acute disease brought on by poisoning or a chronic disease brought on by a vast array of factors like copper storage or another kidney disease like diabetes. No matter the cause, they all mean the same thing, the dog’s liver function is unwell.

The reason for the liver disease does impact how quickly the symptoms appear, so do not rule out liver disease in dogs because symptoms are either sudden or gradual. Both situations can happen with liver disease, depending on its cause.

Chronic Liver Disease in Dogs is not the same as Chronic Liver Failure. It’s a chronic, progressive disease that can lead to complete failure of the liver and death if left untreated or improperly managed.

What are some signs of Chronic Liver Disease?

Some symptoms may be yellowing eyes, vomiting bile acids-stained vomit, abdominal pain caused by enlarged livers pressing on other organs such as kidneys or intestines; occasionally bloating due to fluid accumulation secondary to hepatomegaly (enlarged liver).

Symptoms of liver disease in dogs include:
  • jaundice, yellowing of skin, gums, and eyes
  • vomiting
  • blood in pee
  • blood in poop
  • increased urination
  • increased thirst
  • fluid retention and swelling in the abdomen
  • lack of coordination
  • confusion
  • blindness

It is imperative to have liver disease diagnosed as quickly as possible. The disease ravages the body, damaging other bodily functions even up until 80% of the liver is damaged. This means your dog still maintains some appearance of health while the disease is growing ever more difficult to treat, eventually impossibly to do so. Do not wait until your dog appears seriously ill to have them checked for liver disease.

What Causes Canine Liver Disease and Damage?

There are many causes of liver damage and disease. Below we have listed and discussed some of the main factors in liver diseases.

Getting Older

Dogs are more likely to develop liver damage as they age. Like any other organ, it both starts to function less optimally over time and has had time to suffer from damaging things that have happened to it.


Prescribed medications can cause liver damage because they have to be processed by the liver. Medications contain chemicals that the dog’s liver must filter out like it does toxins, if the amount that passes through is larger than the dog’s liver can handle, it can cause damage and disease. This should not be a problem unless the dog is taking a very large dose of medication, has been placed on a medication for a very long time, or there is already something wrong with the dog’s liver, and your vet should discuss risks versus benefits for either of these situations.

Medications containing the most chemicals that may eventually damage the liver are flea and tick, deworming, vaccinations, and painkilling medications.


Lead, iron, salt, copper, mercury, phosphorus, cleaning supplies, poisons, insect bites and stings, mold, toxic foods, and toxic plants can lead to acute or chronic liver damage depending on the quantities ingested and the number of ingestions. Genetically predisposed dogs will be more at risk with these factors so pet owners should always be aware of their breeds genetic make up if possible.

Copper Storage

If the dog’s body retains too much copper, it will collect in the liver and cause damage and eventually disease. Some breeds like German Shepherds, Golden Retrievers, Labrador Retrievers, Poodles, and Yorkshire Terriers have an increased likelihood of developing copper storage disease.

Fatty Liver Disease

Toy breeds and small breed dogs are prone to developing fatty liver disease where triglycerides build up in the dog’s liver and lead to damage and disease. IT’s a good idea to monitor your dog’s diet in this situation.


There are some genes that do not breed-specific that cause a blood flow issue impacting the liver and leading to damage and disease.

Other Diseases

A dog with diabetes, heartworms, heart disease, pancreatic diseases, or viral and a bacterial infection can develop a damaged and diseased liver. It is important to be on the alert for liver issues, have routine checkups, and be proactive regarding liver health if you have a dog with any of these conditions or diseases.

What is Liver Failure?

If liver disease progresses far enough, it will become irreversibly fatal. At this point, it becomes a matter of quality of life. Liver failure can also come on quickly, such as after a dog ingests a sizeable amount of poison.

Symptoms of liver failure are the same as the ones for liver disease, but they are more pronounced. The dog may end up in a coma at this point.

Stages of Liver Failure in Dogs

Licensed veterinarians grade liver failure in stages, similar to how they do cancer.

The first stage is liver damage and it involves inflammation. The liver is being attacked and is trying to heal itself.

The second stage of liver disease occurs when inflammation has persisted long enough to cause the liver to harden and develop scars. This can be reversible if treatment is begun soon enough.

The third stage of liver disease involves permanent scarring. Treatment at this time consists of trying to preserve the health of the rest of the liver.

The fourth stage is liver failure and this is pretty much end stage liver disease. The liver no longer functions as it should and cannot be healed enough to maintain the health of the dog. Treatments involve maintaining comfort and quality of life for as long as possible.

How to Know Your Dog has Liver Damage or Liver Disease?

Diagnosis of liver disease consists of several potential steps.

The licensed veterinarian will observe the dog, looking for a distended abdomen, gastrointestinal signs, neurologic signs, jaundice, issues with the skin or coat, pale mucous membranes, signs of dehydration, lack of coordination, weight loss and lethargy.

If these symptoms and indications are present, they will move on to a blood test, a complete blood count, then test their bile and urine, and afterwards a biopsy may be needed.

Imaging may be needed to determine if any scarring is present.

How to Treat Liver Damage and Liver Disease

Prevention is the best treatment if you still have the opportunity.

Limit the dog’s exposure to chemicals and toxins like toxic foods and plants, cleaning products, pesticides, etc.

Avoid fatty foods and foods containing toxins, like some human foods.

Educate yourself on vaccinations and medications that are prescribed for your dog. Ensure that your vet is not overprescribing either and is taking into account the risks versus the benefits of the medication. Medications can be a life-saver for your dog, but they can also make them sick, so do not automatically assume all medications are good or bad for your dog. To protect your dog by double-checking the information and weighing out the situation yourself.

Take your dog to yearly checkups. This is particularly important for dogs that are more likely to develop liver disease.

Once liver damage or liver disease has been discovered, treatment may consist of:
  • fluids, electrolytes, and oxygen for acute liver disease
  • liver medications
  • SAM-E or milk thistle
  • changing diet to one higher in vitamins and minerals
  • rest
  • treatment of another condition causing the liver damage

CBD Oil for Canine Liver Disease and Liver Failure

CBD oil could help manage liver damage, and studies show it can also improve the symptoms associated with liver disease and liver failure.

CBD is cannabidiol, a hemp-derived cannabinoid that helps a dog’s body regulate its own cannabinoids. Yes, scientists have discovered that humans and dogs have an endocannabinoid system, cannabinoid receptors all over the body, that play a huge part in managing health and wellness. External cannabinoids like cannabidiol jump start the body’s ability to do what it is already supposed to be doing but may be struggling at.

The many benefits of CBD is dazzling scientists with its ability to impact a broad spectrum of health aspects, some of which may be a huge benefit to your dog with liver disease or an increased risk of developing liver disease.

CBD oil studies show that it is a powerful anti-inflammatory and since inflammation is what damages the liver, you can see how using CBD oil could be beneficial to managing liver damage and its symptoms.

CBD may also:
  • alleviate pain
  • improve mood
  • reduce stress
  • boost energy
  • soothe digestive issues
  • provide nutrients
  • help dogs sleep with higher doses
  • prevent and lessen seizures
  • improve balance

While undergoing treatments for liver disease, or dealing with a failed liver, CBD can improve the dog’s life, easing symptoms that make treatments less effective and making them feel better.

Are there downsides to using CBD oil for liver failure in dogs?

CBD comes from the cannabis family, and it may share many health benefits with marijuana, but it does not contain THC, so you don’t have to worry about your dog being “high.” Minimal, if any.

CBD is not a healthy hammer, whopping a dog’s body with feel good benefits and then leaving them to crash. It manages and regulates functions that help the dog’s body maintain its own health.

There are virtually no side effects. If the dog takes a very large dose of CBD, they may experience diarrhea, changes in appetite, or sedation. That’s a far safer sounding list of side effects than most prescription medications can offer.

CBD is not tried and true like traditional medications. The science is still new regarding it, and while it does show great promise and even veterinarians consider it a worthy secondary or primary treatment in many cases, you don’t want to rule out the possibility that another route may prove necessary. CBD is best used when other treatments are proven ineffective, the side effects of traditional treatment are threatening its success, or a disease has gone too far to be treated with conventional means.

Using CBD Oil

There are several types of CBD oil you can purchase for your dog with liver disease:
  • oil tinctures
  • extract concentrates
  • capsules
  • treats

CBD Oil tinctures come with a dropper or sprayer so the oil can be applied directly to the dog’s mouth or to their food. It is often flavored to mask the distinctive and often off-putting taste of hemp.

CBD Capsules avoid the whole taste issue and can be easier to get into some dogs. They should contain only CBD oil and what ingredients are necessary to turn it into a capsule. CBD Extract concentrates contain nothing but CBD oil and can be applied to the dog’s mouth or their food. These are the most cost-effective option and guaranteed to be free of any weird ingredients, but they may be harder to get into a dog because of the taste.

Hemp Dog Treats are the easiest delivery method for CBD as treats are fun. You can add these to your pet’s diet or replace a current treat with them. Check the ingredients list for fat, copper, or any other substance a dog shouldn’t have for liver concerns. They shouldn’t be in there, but it’s wise to look.

Dosing CBD for pets instructions come on the package of the CBD product and will be based on the dog’s size. Very small, large, young, old, or sick dogs may have special dosing requirements. It is wise to consult your veterinarian to discuss CBD use so they can help you determine the exact dosages for your individual dog and so they’ll know the dog is taking CBD should it impact their treatments.

Purchasing CBD Oil

There are certain things you should look for when purchasing CBD oil.

Full-spectrum versus CBD isolate

Both of these types of CBD are quite good, but you should know which one you are buying because some people find that one works better than the other for their unique situation and you need to know which ones do work for your dog so you can buy it again.

CBD isolate is just CBD, while full-spectrum is CBD with other cannabinoids, terpenes, and nutrients found in the hemp plant. Full-spectrum is actually the most popular option and may be the best one to choose for your dog with liver disease as it also contains additional nutrients. Should full-spectrum let you down, don’t give up on CBD altogether. You may find that CBD isolate works for your dog.

Third-party Testing

Tragically, all CBD products are not legitimate. Some manufacturers sell CBD products that do not contain enough CBD or any CBD at all! This is why reputable CBD manufacturers supply their third-party lab test results to prove they are offering what they say they’re offering.

Extraction Method

Choose manufacturers who say they used the CO2 extraction method as this is the safest and purest one.


Look for CBD products with only necessary, safe, and natural ingredients. Organic is best. As mentioned in the treat section, take special precautions to check for ingredients that may be harmful to the liver.

How Can CBD Oil Help Treat Dogs with Liver Issues

Many dogs will experience liver issues during their lifetime. Liver problems are common in dogs so every pet owner should be aware of and understand the symptoms of liver failure. Being cognizant of this will prevent potential liver issues down the road.

Recently, CBD oil has become very popular. Many dog owners are starting to learn how CBD oil can treat their dogs with liver issues and act as a great supplement. In this blog, we’ll touch on liver function and how CBD oil can help dogs with liver issues.

Liver Function

The second-largest organ in the dog’s body is the liver. The first largest is the skin. The liver plays a key role in metabolism and filters out toxins and waste found in medications and foods.

It is responsible for over 1500 different biological processes including:

  • Creating bile to aid digestion and break down fats
  • Metabolizing minerals, vitamins, carbohydrates, protein, and fat
  • Filtering the blood
  • Regulating blood levels of amino acids
  • Producing proteins that are responsible for blood clotting
  • Storing iron that’s used in the hemoglobin process
  • Filtering bacteria from the bloodstream to fight infections

Liver Disease

When a dog has liver disease, its liver is compromised so it doesn’t function properly. It may have trouble performing some or all of the biological processes. This can negatively impact the dog’s health and quality of life.

There are different types of liver disease in dogs. For instance, liver tumors can put pressure on the liver and surrounding organs in your dog’s body. Some dogs may have a bile duct obstruction in which the tubes that carry bile from the liver to the gallbladder get blocked.

Other dogs may have a liver shunt or portosystemic shunt. The blood from the spleen, pancreas, intestines, and stomach bypass the liver so the blood is not properly detoxified.

Symptoms of Canine Liver Disease

Depending on the type of liver disease your dog is experiencing, the symptoms will vary. Visiting your dog’s vet regularly is crucial. During these visits, have the vet test your dog’s blood and thoroughly examine the body.

Being aware of these symptoms and getting regular exams is important to prevent putting your dog to sleep early as often times you may not initially see any symptoms. By the time you notice it, the liver disease may have progressed far enough to late stages that it will be too late to treat your dog. Thus, early detection is key.

If you see any yellowing in your dog’s eyes, skin, tongue, or mucous membranes, it may be a sign that your dog’s liver may not be functioning normally. Other symptoms of dog liver issues include:

  • Vomiting
  • Loss of appetite
  • Swollen abdomen
  • Diarrhea
  • Lethargic or low energy
  • Unsteady gait or loss of balance
  • Seizure
  • Fever

Top 3 Daily Exposures That Can Lead to Liver Issues in Dogs

Dogs live in the same environment as humans. Because of that, they are exposed to the same chemicals humans are exposed to, which can affect their liver health.

Below we will discuss three primary exposures that can compromise your dog’s liver health and function.

If you’re feeding your dog commercial dog food, you may not be aware that they are often contaminated with a toxin called aflatoxins. Aflatoxins are produced by certain fungi found in agricultural crops such as tree nuts, corn, peanuts, and cottonseed.

Eating commercial pet food can contribute to poor health in dogs. The aflatoxins can not be killed in high temperatures so even if you heat up the pet food, the toxin is still in there.

When the aflatoxins enter the body, it binds with your dog’s DNA and causes cell mutations. Constant consumption of aflatoxins has been linked to an increased risk of liver cancer. No matter if the commercial pet food is cheap or premium quality, they contain aflatoxins.

The plants in our backyard or in our neighbor’s front yard may be toxic to our dogs. When our dogs head out for their daily walks to do their business, it’s natural for them to sniff around and even chew on plants that they see.

For example, many pet owners grow aloe vera in their backyard or patio. Although aloe is considered a medicinal plant for humans, its level of toxicity is considered mild to moderate for dogs. Other plants that are considered toxic to dogs are autumn crocus, begonia, castor bean, daffodil, lilies, sago palm, and tomato leaves.

Many dogs naturally lie on the floor, on the furniture, bathe in the bathtub and even counter surf. Pet owners frequently clean their floor or bathtub with household cleaning products that contain highly toxic ingredients.

For instance, bleach or chlorine is very dangerous for dogs. Bleach can be found in toilet bowl cleaners, dishwashing detergent, and laundry detergent. If dogs swallow it, the bleach can burn the inside of their mouth or throat, causing them to vomit and have seizures.

Not only are dogs breathing in the toxins, but they are also absorbing them through their skin when lying on the floor or through their paw pads when they’re walking around the house. Constant exposure to many household cleaning products can cause liver damage and poisoning.

How can CBD Oil Help Treat Liver Issues in Dogs

If your dog has liver issues, CBD oil can help improve its life. You can use CBD oil as nutritional supplements, in diet, and under veterinary supervision.

Pet owners should not overlook CBD oil as a treatment option because it provides huge potential benefits for dogs with liver issues. The CBD oil helps manage liver damage and improve the symptoms associated with liver issues.

The dog’s body has an endocannabinoid system in which the cannabinoid receptors help to manage their health and wellness. When dogs take CBD oil, it helps their body regulate their own cannabinoids.

Many vets will also prescribe high-quality CBD oil that is carefully sourced, organically grown, and carefully tested for dogs with liver disease.

There are many positive benefits of CBD oil. It can reduce the inflammation that is damaging the liver and help manage liver damage and symptoms.

Here is a list of benefits from taking CBD oil:

  • Alleviate symptoms including diarrhea, vomiting, nausea, vertigo
  • Maintain a healthy appetite especially if your dog is losing appetite
  • Better sleep
  • Reduce pain and inflammation
  • Prevent or slow down tumor growth
  • No harmful side effects
  • Easy to metabolized
  • Reduce or prevent seizures
  • Improve your dog’s mood and physical balance
  • Boost your dog’s energy level
  • Alleviate digestive issues
  • Provide nutrients

By taking CBD oil, your dog will feel more comfortable and start to enjoy his life again. His quality of life will improve significantly after taking CBD oil.

When Not To Use CBD Oil for Dogs with Liver Disease

While there are no side effects for dogs taking CBD oil, it’s a good idea to avoid taking very large doses of CBD. This can cause diarrhea and a change in appetite.

There are two cases when you should not use CBD oil to treat liver disease. The first is when your dog has congenital liver shunts. The second is when your dog is on pharmaceuticals. CBD can interfere with the medication that your vet prescribed.

4 Types of CBD Oil for Dogs with Liver Disease

The good news is that there are four types of CBD oil available for dogs with liver disease. If one of them doesn’t work for your dog, the others may.

With capsules, you can put it in the dog’s food or directly into their mouth. Your dog won’t taste it and it is easier to get them to have it.

When it comes to extract concentrates, the amount of dosage varies depending on your dog’s size and the stage of the disease they are in. Ask your vet for the appropriate dosage amount.

Oil tinctures come with either a sprayer or dropper. This way the oil is applied directly to the dog’s mouth or into their food. Fortunately, it is flavored so your dog doesn’t taste the hemp flavor.

Treats are fun so you can replace your dog’s current treat with CBD treats. Make sure to check the ingredients first before you give these treats to your dog.
