Is cbd oil safe for dogs with dementia

6 Reasons NOT to Give CBD Oil to Your Dog with Dementia

The plant cannabis, which provides both hemp and marijuana, has a complex chemical makeup. Besides providing many practical products in the hemp form, it contains more than 100 “cannabinoids.” These are psychoactive chemical compounds, i.e., they affect the brain. A major compound is cannabidiol, or CBD.

The molecular structure of the chemical CBD

Some people recommend CBD oil for senior dogs. This is with the intent of treating symptoms of canine cognitive dysfunction, anxiety, and more. Please be aware that in doing so they are making a medical recommendation. If they don’t have veterinary credentials, this is against the law in most countries. The Food and Drug Administration in the U.S. regularly warns the companies selling CBD oil for people and dogs that they must not market them as medications. The list below will tell you why.

Here are some reasons to think twice about adding CBD to your senior dog’s meds.

1. CBD oil has not been tested as a treatment for dementia in dogs. This one reason should be enough. Do you want to experiment on your dog with a substance that may affect their brain? Research on the many compounds from the cannabis plant is still in its infancy. There has been some progress, but it hasn’t gotten to dogs yet. So far, there are findings that CBD may provide mild help for humans with chronic pain, pain from multiple sclerosis, and with nausea from chemotherapy. There are indications that it might help with epileptic seizures. However, there is as yet no evidence that cannabinoids help with human dementia.

But even if there were evidence for CBD helping humans with dementia, we can’t assume that it works for dogs. Some helpful drugs for humans are actually toxic to dogs.

There are several clinical trials with cannabis going on for dogs. They are not for dementia or anxiety. One is for dogs with epileptic seizures. It does look promising. Here is a link to the clinical trial from Colorado State University, and here is an article about the study. Note that until the study is completed and replicated, there is not enough evidence even for this use of CBD. The two others, both for joint pain and arthritis, are through Cornell University and Colorado State. They are also said to be promising, and the Colorado State one will soon be published.

One peer-reviewed study published recently reported the testing of CBD for noise-induced fear in dogs. The CBD was used by itself and in combination with the prescription drug trazodone. The CBD not only didn’t show any fear-reducing or relaxing effects, it actually appeared to lower the efficacy of trazodone when used in combination.

2. Quality control for CBD products is poor. Some products advertised as having CBD oil don’t have a trace of the oil in them at all. Some products were contaminated with other compounds. The ones that do have it contain hugely varying amounts compared to each other. Here are the warning letters sent out by the FDA in 2015, 2016, and 2017 to CBD oil companies in violation of the law. They received the warnings because there was no CBD in the product, there was contamination with other substances, or because they made illegal claims. Buyer beware!

3. Safe dosages have not yet been determined. This is an offshoot of #1 but merits its own section. We often don’t realize all the things research needs to tell us. When a substance is studied, the research goes far beyond whether it “works.” It has to be determined whether the substance has any adverse effects or drug interactions (see #4). Dosage needs to be figured out. Some cannabinoids are toxic to dogs at certain dosages. For instance, this article reports the deaths of two dogs from marijuana-infused butter. Here is a large study of the toxic effects of marijuana (not CBD) in dogs. While cannabidiol is thought to be less toxic than some other compounds in marijuana, there is still a risk from amounts or contaminants, especially if you are buying from a company who has been cited in the past.

4. Interactions with other drugs and supplements are unknown. Senior dogs, with or without dementia, are sometimes on several medications and/or supplements. Veterinarians keep our dogs safe from negative effects because they know about drug interactions. With the exception of the one study mentioned above that showed an undesirable interaction with trazodone, the statistical information for CBD simply isn’t there yet.

5. Drugs that affect the brain and neurological system affect individuals very differently. Don’t forget: CBD oil affects the brain. Many psychoactive drugs have different effects on individuals. This is true for people and for dogs. Many people have to try several different antidepressants before finding one that works. The “wrong” antidepressant can make depression worse. Likewise, my fearful dog who takes medication didn’t do well on the first one we tried but did on the second. It’s unlikely that there is a “one size fits all” solution with this kind of drug.

6. When we try a remedy, we tend to be biased about it. We all want to believe that we are free from bias, but it is a hard thing to achieve. When we invest our time and money on a solution for a beloved dog, we desperately want it to work. There is a specific bias that pops up easily in this situation called “regression to the mean.” The way this works is that many diseases and conditions have symptoms that come and go, get worse, then better again. We typically look for help when our dogs are going through a hard time. Then whatever intervention we have chosen is likely to look effective. This is because what naturally happens after the symptoms have bottomed out for a while is that the dog gets better (for a while). Then we attribute it to the therapy we started, when actually there may not have been any relationship at all. Besides regression to the mean, there is also the placebo effect. Not for the dogs, but for the people. When we give medications, we believe they work, even if the evidence doesn’t necessarily say so. This has been shown to happen to dog owners and even vets regarding whether a certain medication worked.

For more information on how our brains are automatically biased in certain situations, check out Kahneman’s book, Thinking Fast and Slow. It has many, many examples.

Natural Treatment of Canine Cognitive Dysfunction

Many natural remedies and supplements are available that claim to help dogs with dementia. But only a few have been shown to work in clinical studies. Check out the treatment page on this blog for a list. And most important, talk to your vet before even considering trying these supplements. Supplements are made of chemicals, just like prescription drugs, only are much less controlled. Supplements can interfere with each other and with prescription medications. Only your vet can tell you if they are safe for your individual dog.

But It Worked for My Dog!

As noted above in #6, most of us are hopeful when we try a new treatment for ourselves, a human loved one, or our dog. What usually happens, because of regression to the mean and confirmation bias, is that we perceive a benefit right away. Then it seems to dwindle. How many times have you seen someone report, “This treatment helped at first but it’s not helping anymore.” It may not have been helping at all; it could just appear to help from the timing.

If you are serious about testing a medical intervention or supplement for dementia, work with your vet. And be sure you keep a journal of your dog’s symptoms starting before you give them the treatment. That will give you an objective measure as a benchmark to help you determine whether your dog is actually improving.

CBD Oil for Dog Dementia

Have you started to notice that your older dog may no longer know where they are? They may also be wandering around the house and seem like they are lost, or easily get stuck in a room and cannot figure out how to get out. All these are signs of dementia in your dog.

There are many things that can be done to help your dog suffering from dementia. If you have noticed any of these signs in your dog, it is best to consult with your vet to find the best course of treatment for your dog, but you should strongly consider CBD as an option for helping them.

What is dementia in dogs?

Dog dementia can also be called canine cognitive dysfunction or CCD. This is very similar to Alzheimer’s in people. Your dog will have a slow deterioration of mental function. This is something that is commonly seen in older dogs.

There are not any specific signs that would lead you to think that your dog would have dementia, and many of these signs could also be due to a different disease. Symptoms of dementia in dogs include:

Pacing behind doors

A dog who has dementia will usually pace around the house. Many times, they will act like they are lost. Your dog will usually never settle down and sometimes barely sleep. Dogs who have dementia will have trouble remembering normal things like where their food and water bowls are located. They may even go to the wrong door in the house to go outside, or they may go to the opposite side of the door than what they are supposed to. All these signs are commonly seen in a dog with dementia.

Increased anxiety

If your dog has dementia, they may be more anxious than they use to. You may notice that they always want to be right beside you, and when you are gone, they are pacing more. Most dogs will start to want you to be near them more and seem more anxious when you are gone.

Hiding from activities

Your dog may not want to participate in some of their normal activities. They may have loved to go for a walk or love to chase the ball. If they have dementia, they may no longer be excited about these activities. Many times you may find your dog hiding under the bed or behind the furniture when you normally do these activities.

Not recognizing family members

If your dog does not easily recognize someone or another animal that they are used to being around and have always known, this could be a common sign of dementia. Your dog may now bark when a family member or friend comes over. The other animals that they have lived with all of their life they act as they do not know them is very commonly seen in dogs with dementia.

Defecating and urinating indoors

Dogs that have been potty trained are now starting to have accidents in your home. This can be a sign that your dog has dementia but could be due to a urinary tract infection or another disease. If your dog is having accidents, your vet can test your dog’s urine to help you rule out other conditions.

Barking for no reason

Some dogs with dementia will bark at things that have always be present in the house or just randomly start to bark. This may be in the middle of the night or during the day. Some dogs will bark non-stop all day long. If your dog just starts to bark for no reason at all, they may have dementia.

CBD is cannabidiol and is found in the hemp plants. Unlike what some people may think CBD does not contain any THC. THC is the chemical that is found in marijuana that is responsible for the euphoric state. CBD interacts with the endocannabinoid system in the brain to produce a variety of effects on the body.

How do you know if your dog has dementia?

CCD is a dysfunction that is usually referred to as dog dementia. There are no definitive signs that can help you determine whether your dog has dementia or not. However, you still can notice dementia due to a few common symptoms below:

2. Persistent Barking
barking louder and more often than normal is also the sign of dementia for dogs. They can bark at any time and anything for no apparent cause. Some dogs even do not need to take breaks and continue to bark, this is one of the most obvious symptoms of dementia.
3. Physical Activity Limitations
Is your dog used to going out for walking in the park but they just lost interest? Or Does your dog seem uninterested in anything? When your dog is trying to stop their normally physical activity, or if you see him lie under the bed, it is reasonable to say that they’re suffering from dementia

Suffering from anxiety or another underlying disorder can be the reason that make your dog lost control of his bowels. It is better to assist him and reassure him that everything will be well.
6. Loss of Appetite
With CCD or dementia, you can experience a decline or rise in appetite. This is mostly attributed to increased anxiety, although it’s also possible that he just forgot to feed. He won’t be able to feed until he remembers, or until you put his food bowl in front of her.
7. Hearing and/or vision changes
There is one thing to note that hearing or vision changes will trigger some of the same symptoms. A dog who cannot be able to hearing or vision as normal, can become disoriented and anxious as, this is obvious. To rule out CCD, ask the veterinarian for testing hearing and vision faculty.
