How CBD Can Help with Heart Disease in Dogs
Many people don’t realize their dogs can get heart disease just like humans do or that there is such as a thing as a dog heart attack. This post will explain all you need to know about heart disease and congenital heart failure in dogs as well as CBD heart benefits that may make a life-saving difference for your pet.
What is Heart Disease in Dogs?
There are several conditions that fall under the category of heart disease. Coronary artery diseases that humans are more likely to get from their diet, is not a huge problem for dogs, though they can get it.
There are unfortunately plenty of other heart diseases for them to potentially get. All of these diseases are very serious, leading to diminished quality of life and the potential for heart attacks and strokes in dogs.
Most Common Types of Heart Disease in Dogs
Canine Valvular Heart Disease
Canine Valvular heart disease is a thickening and breakdown of the valves of the heart. There are valves that are between the chambers of the heart as well as leaving the ventricles. When these valves get thick and breakdown they can not close properly causing a back-flow of blood.
Heartworm disease comes from a dog being bitten by a mosquito carrying heartworm larvae. These nasty parasites (are there any parasites that aren’t nasty), multiply in the dog’s vascular system, impeding the workings of the heart and larger blood vessels.
They can grow fast and live a long time, eventually completely clogging the dog’s vascular system if not treated. Treated heartworm disease can still leave permanent damage if the disease progressed far enough.
Myocardial disease is caused from the heart muscle overworking which causes thickening of the wall of the heart. This leads to a smaller chamber inside the heart for blood.
Mitral Valve Disease
Mitral Valve Disease involves the development of a weak valve between the left atrium and the left ventricle, and it usually more common in small dogs.
Canine Cardiac Arrhythmias
Canine Cardiac Arrhythmias are irregular heartbeats that come about because of a problem with the electrical impulses controlling heartbeat.
Canine Pericardial disease involves the buildup of fluid in the sac that surrounds the heart and restricts its normal beating.
Congenital Heart Defects
There are a host of congenital heart defects as well, meaning they are inherited and being at birth though the symptoms may not appear until later.
Congestive Heart Failure
Heart disease can lead to congestive heart failure, where the heart either becomes too thick and rigid to fill properly, too weak and unsubstantial to pump properly, or the valves become so dysfunctional that they cause severe lack of blood flow.
Symptoms of Heart Disease in Dogs
Most heart diseases in dogs will cause some of the same symptoms:
- difficult breathing
- shortness of breath
- reduction or increase in appetite
- weight loss or gain
- swollen abdomen
- unwillingness to exercise
- dry coughing after exercise
- dry coughing at night
Causes of Heart Disease in Dogs?
Sometimes dogs just inherited the tendency to get heart disease. If a breeder discovers one of their dogs has an inheritable heart disease, they are supposed to stop breeding them. But dogs not bred deliberately have no such protections and even those protections for bred dogs may not be foolproof.
Heartworms cause a specific kind of heart disease and the dog gets it from being bitten by a mosquito carrying heartworm larvae.
Obesity and/or a poor diet can cause heart disease in dogs, much like it does in humans. However, obesity in dogs causing heart disease is not very common.
Certain dog breeds are more likely to develop specific heart diseases. It is important to discuss risk factors for heart disease with your licensed veterinarian.
Dogs are also just more likely to develop a heart disease as they get older. It’s not guaranteed, but the risk naturally increases. You should be on the lookout for symptoms of heart disease at this point and proactive about protecting the dog’s heart.
Preventing Heart Disease in Dogs
Educate yourself on your dog’s breed and risk factors for heart disease. There may be particular recommendations for preventing the heart disease they are prone to.
Maintain recommended vet visits to catch heart disease early.
Do not fall prey to the fat dog is a cute dog temptation, no matter how tempting it is. Excess weight can hinder your dog’s quality of life and lead to heart disease.
Be mindful of diet. Dog foods can contain too much fat. Peas, lentils, legumes, and potatoes can be found in dog foods and they can cause Myocardial disease. Grain-free dog foods may also present problems.
As you might tell from the foods already mentioned, human food should be withheld or greatly limited. You could speak to your vet about your dog’s diet in relation to their individual heart health.
Choose a heartworm prevention medication or natural prevention method to keep your dog from getting heartworms.
Outlook for a Dog with Heart Disease
We’ll start with the worst-case scenarios first.
Heart disease in dogs can lead to:
- heart attacks
- muscle wasting
- severe weight loss
- difficulty breathing
- no desire or ability to play or exercise
- trouble sleeping
- leg swelling
- limited mobility from lack of energy or severe muscle wasting
- nutritional deficiencies
- poor quality of life
The positive side is that your dog can live a long and happy life with heart disease, if you catch it early and are proactive with their health.
Routine checkups and preventative measures are the safest way to protect your dog from heart disease and to catch it early.
Second to that, you want to get them to the vet at the earliest signs of a problem.
Some signs you should take your dog to the vet (aside from routine checkups):
- if a dog has a cough that lasts longer than three days
- any sign of shortness of breath or difficulty breathing
- a change in behavior
- a decrease in excitement about exercise and play
- shortened play times
- restlessness at night
- a potbelly
- decreased appetite
Diagnosing Heart Disease in Dogs
The diagnostic process may include:
- listening to symptoms
- visual inspection of dog’s behavior and appearance
- listening to their heart
- cardiac catheterization
- blood tests
- urine tests
Treatment Options for Heart Disease in Dogs
Diet is important for improving symptoms and outcome for a dog with heart disease and heart failure. You will need to discuss this with your licensed veterinarian because there is no one diet that helps with heart problems.
Different conditions and stages have different diet requirements. Your dog may need to reduce sodium intake, gain muscle, lose weight, correct nutrient deficiencies, add nutrients that strengthen the heart, and more.
Heartworm treatments consist of killing or removing the heartworms.
It is common for heartworm treatments to cause:
- loss of appetite
- lack of thirst
- muscle tremors
- dilated pupils
One treatment method is surgery to remove all heartworms from the dog’s heart and blood stream.
Some heartworm treatments contain arsenic and cause inflammation. No one wants to give a dog an arsenic-based medication, which is one reason why vets so strongly urge heartworm protection.
When a dog’s heart disease has become congestive heart failure, veterinarians typically prescribe ACE-inhibitors, or angiotensin-converting enzyme inhibitors. These treat the symptoms and lengthen the life of the dog by relaxing the blood vessels.
ACE-inhibitors can cause serious side effects:
Long-term use of ACE-inhibitors and using ACE-inhibitors with other medications requires routine medical evaluation to ensure other health conditions do not occur, such as abnormally high levels of nitrogen in the blood or renal issues.
Dogs can be allergic to ACE-inhibitors. They also interact with a bunch of other medications and pregnant and lactating dogs can’t use them.
When fluid buildup is a factor, veterinarians sometimes prescribe diuretics to reduce the buildup.
Side effects of diuretics in high quantities include:
- excess thirst
- decreased urination
- low blood pressure
None of these are exactly bad drugs. They can be life-savers for your dog, if the side effects or other health concerns don’t make it impossible for them to take them.
Medicinal heartworm preventatives are controversial. Many people don’t like maintaining a constant or seasonal dose of a drug in their dog just to prevent a disease, particularly when the drug can have serious and life-threatening side effects.
Side effects of heartworm prevention medications include:
But heartworms can cause permanent damage to the dog’s vascular system and the treatments are at least as scary, if not often more so, than the preventatives.
If you decide medicinal heartworm preventatives are not right for your dog, discuss holistic alternatives with your vet, or seek a holistic vet. Unless your dog has virtually no chance of encountering a mosquito, some prevention is necessary.
How CBD Can Help with Heart Disease in Dogs
CBD oil is one of the most popular and natural ways to manage heart disease in dogs. It may also be used as a way to possibly ease the side effects of the traditional medications so that your dog can continue to use it.
CBD oil can help dogs with heart disease by:
- decreasing inflammation
- managing pain
- calming anxiety
- reducing the frequency and severity of seizures
- potentially protecting the heart itself from arrhythmias and infarctions
- protecting the brain from and repairing brain damage
- reducing nausea
- improving appetite
- helping them sleep
- replacing nutrients
Risks Associated with CBD Oil
CBD oil poses few concerns. There is no known instance of a CBD oil overdose. if you give a dog too much CBD oil, they may experience side effects such as sedation, loss of appetite, or diarrhea.
CBD oil does alter how the dog’s liver absorbs medications, so their vet should know that they are being given CBD oil so they can dose any other medications accordingly.
The science is new regarding CBD oil, so no one is as familiar with the effectiveness or the risks as they are with traditional medications.
It makes a safe and alternative treatment for heart disease should the dog not respond to traditional medications, not being able to take traditional medications, or need relief from the side effects of traditional medications in order to continue taking them.
It is wise to keep your dog’s vet abreast of your use of CBD oil to ensure it is doing for your dog what you’re purchasing it for.
Using CBD Oil
The first step is to find a CBD oil product for pets.
CBD oil comes in several forms for pets to suit your needs and their tastes:
- oil tinctures
- extract concentrates
Treats are the most fun and therefore the easiest to get in a dog. If your dog hates taking medicine, these may be the way to go. They come in both crunchy and chewy forms to suit each individual doggy’s taste buds.
Oil tinctures are also pretty easy as they are often flavored and come in a convenient liquid form that can be administered by drops or sprays. Your dog may take this fine directly by mouth or you may apply it to their food.
Some tinctures are not flavored. If your dog doesn’t like them, you can always add it to a food that can mask the distinctive hemp taste. Tinctures offer the greatest control for varying doses, particularly ones with droppers.
Extract concentrates are like oil tinctures except that they are just CBD oil and come out in thick little beads. You can measure the number of drops to get the dose you want. These also can be given directly by mouth or applied to food.
Capsules eliminate any taste concerns and are easy to give to dogs who are tolerant of the powder in the pills.
Dosing CBD Oil
Some CBD oil products, like capsules and treats will have a certain dose per capsule or treat stated on the product packaging. You can increase the dosage as needed by giving another capsule or treat.
Other CBD oil products tell you how much cannabidiol is in one measurement of the product, a drop, spray, or bead. You then measure out how many of these to give to reach the dose desired.
Research the suggested dose of CBD for the dog’s ailment, whether it is the heart condition itself, to sleep, to improve digestion, etc. Then start with the lowest recommended dose and work up in increments to whatever achieves results for your dog.
It’s important to increase gradually, otherwise you won’t be able to accurately judge the effectiveness of the dose. Cannabidiol begins working immediately, but the full effects may not appear for a few weeks.
It would be needless to increase the dose before this time, unless the dog’s ailment is so dire or they are in so much pain that they can’t wait.
You can gradually increase their dose in as short a time as two days or use CBD oil with another treatment until the full effects can be seen.
Do be aware that very small, large, young, old, or sick dogs require different dosages. Consult a vet or our cbd dosing guide for specific dosing for the individual dog.
Purchasing CBD Oil
Before purchasing CBD oil, you’ll need to know some things to look for.
Full-spectrum vs CBD isolate
When it comes to full spectrum vs CBD isolate, it’s important to note their differences and what might work best for your needs. Full-spectrum CBD oil contains other cannabinoids, terpenes, and nutrients found in the hemp plant while CBD isolate is just cannabidiol. Most people actually prefer full-spectrum, attracted to the additional benefits, but some people say CBD isolate works best for their needs.
The choice of which one to start with is up to you, but if your dog has a digestive symptom, they may gain additional benefits from the nutrients in full-spectrum CBD oil.
Some CBD oil manufacturers are, tragically, not what they claim. The ones who are reputable prove this by providing third-party lab test results showing what is in their products and what is not. This way you know you’re buying what you think you’re buying.
You should check the website for the CBD oil product to see where the manufacturer says they acquired their CBD oil or hemp. Some grow it themselves while others get the CBD oil from someone else. Both are okay as long as they say it was grown in a country with safe growing regulations.
Some extraction methods are better than others, like the CO2 extraction method. Choose it. It’s the safest and purest.
Select a CBD oil product that contains as few ingredients as possible and only ones that are necessary and safe. You should very easily be able to find natural and organic CBD oil products as well.

Heart Murmur in Dogs Grades, Life Expectancy and Dog Heart Failure
Heart Murmur in Dogs Grades, Life Expectancy and Dog Heart Failure
A heart murmur is an abnormal sound indicating turbulence in the flow of blood. While it’s not a disease it can indicate heart trouble. Some of the conditions that can be shown is endocarditis, valve abnormalities, or stenosis. If you hear a vibration or a sound that is coming from the heart it can indicate a heart murmur.
Causes of Heart Murmurs in Dogs
A heart murmur is different than a heart failure, but can pose potential life-threatening risks. Implications of a heart murmur can mean that the heart is having issues can lead into dog heart failure. Dog Heart Murmur can be inherited at birth, but is also known to be acquired as dogs age. Cavalier King Charles Spaniel’s have a very high risk of developing a murmur.
Dog breeders typical use dogs with healthy hard, but it is difficult to guarantee that dog heart murmur won’t exist or become a problem.
Here is a list of some causes of dog heart murmur
- Abnormality of the heart
- Swelling/Inflammation of the heart
- Incomplete closing of a valve
- Narrowing of the arteries
Diagnosis of Dog Heart Murmurs Can Show Possible Life Expectancy
Heart murmur for dogs is graded on a scale of 1 – VI and is based off of the sound and vibration of the heart murmur. Below we’ll highlight the different grades and a brief explanation of each.
- Grade I: Barely audible a vet would barely be able to notice the sounds or vibration.
- Grade II: Soft, but noticeable if the vet uses a stethoscope.
- Grade III: Heart murmurs related to mechanics of blood circulation are minimum Grade III
- Grade IV: Loud murmur
- Grade V: Very loud murmur. The vibration can be felt through the chest.
- Grade VI: The vibration will be felt through the dog’s chest wall and it will be very loud
Some medical imagine may also be needed to properly diagnose the underlying cause of the heart murmurs. Several conditions can be tied with heart murmurs such as valve abnormality, swelling or inflammation of the heart. An ultrasound can be used to detect these medical issues.
Usually puppies or younger dogs will have a Grade 1 heart murmur which does not signify any illness, but should still be checked out by your vet.
Dog Heart Murmurs Treatment Can Help With Life Expectancy
When being diagnoses with heart murmurs it is usually an indicator that it is a condition of the heart and the surrounding arteries. Various treatments can be used or provided, but usually we want to find out the cause of the heart murmur or the underlying issue to properly diagnose it and treat it. Sometimes this involved a change in diet and exercise . Other times it could be a small heart or valve defects that can cause a quiet murmur, but then medical imaging would be used to find out the serious defect of the condition.
CBD Oil for Dogs and Heart Murmur Life Expectancy
CBD Oil is for dogs is typically used for dog heart murmurs, but not as a cure all medicine. It is a health supplement that promotes good health and a healthy balance in the body. CBD oil is used to activate the Endocannabinoid receptors inside of your dogs nervous systems which allows them to stay calm, have less anxiety and control inflammation. The most important role CBD oil can play for dogs with heart murmur is its anti-inflammatory properties which reduce swelling and inflammation in the heart.
Dog heart murmur life expectancy varies on the age of your dog and the severity of the condition. If it leads to dog heart failure than the life expectancy will vary. CBD oil will not ensure that your dogs life expectancy will be prolonged, but it will help manage the pain and lower the symptoms making life easier for your dog. It is a supplement that will help with relief during this hard time.
