The aging journey for dogs is remarkably similar to that of humans. As pets grow older, they often stop being as energetic as they used to be. While this can be due to natural changes in activity levels or preferences, a lack of liveliness could also be attributed to aches, pains, and even depression.
Helping a pet live a full and active life regardless of its age is a challenge for many owners. However, even a strong health routine may not be enough. That's why some owners explore alternative options like CBD.
CBD has the potential to improve your dog's quality of life. While more studies are needed to confirm its positive effects, many dog lovers around the world are already incorporating CBD into their pets' daily routines. Below are a few reasons why owners choose CBD and how it may work.
When Is a Dog Considered a Senior?
A dog's status as a senior depends on its size. Smaller dogs typically enter their senior years between 10 and 12 years old. Meanwhile, large dogs generally age faster and are considered seniors between 6 and 8 years old.
The reason for the discrepancy is the stress a larger body puts on a dog's organs. A dachshund's heart doesn't have to work as hard as a Great Dane's, so it typically ages more slowly.
When a dog enters its senior years, it starts to experience both physical and mental changes. Recognizing these changes early and helping your dog through them can significantly improve its quality of life in its later years.
Common Signs of Aging in Dogs
For some dogs, these changes can be sudden, while for others, they develop so gradually that they're easy to overlook. As your pet gets older, it's important to pay close attention to its behavior. Otherwise, you may miss opportunities to support your dog's health and comfort. Some of the most common signs of aging include:
- Slower movement: The dog moves much more slowly both around the house and during walks. It may be happier to go indoors after a few minutes outside rather than spend hours playing in the yard.
- Joint stiffness: You may notice that it is no longer as easy for the dog to jump while playing or climb stairs. It may also take longer to stand up after resting.
- Reduced activity: Your dog may not seem interested in playing as much as it used to.
- Sleep changes: Some older dogs sleep more than they did when they were younger, taking additional naps throughout the day. Others, however, may have difficulty falling asleep or staying asleep.
- Appetite changes: Senior dogs may experience changes in appetite that can go either way. Some pets start eating more than they used to, while others lose interest even in their favorite treats.
- Sensory changes: While these changes can be harder to notice, you may find that your dog doesn't hear or see as well as it once did.
All of these changes are a natural part of the aging process. However, if you notice any of them, your first step should be to consult your veterinarian. Sometimes, they may be caused by an underlying medical condition that requires treatment rather than normal aging alone.
How CBD Works
CBD interacts with the endocannabinoid system (ECS), a complex communication network found in all mammals. The ECS plays a role in helping regulate functions including:
- Mood
- Sleep
- Appetite
- Pain perception
- Immune function
The ECS has one primary job: helping maintain balance within the body. This process is called homeostasis, which helps the body adapt and function properly even as internal and external conditions change.
As dogs get older, maintaining this balance can become more difficult. Their bodies may not respond to physical stress, inflammation, or everyday discomfort as effectively as they did when they were younger.
CBD does not directly alter how the ECS works. Instead, it is thought to support the ECS's normal function by interacting with components of the system, although researchers are still studying exactly how this occurs. This may be one reason CBD has the potential to help support comfort and overall well-being in senior dogs.
Potential Benefits of CBD for Old Dogs
Studies on CBD's effects in dogs are still limited. However, early research suggests that this cannabinoid may have the potential to improve a dog's quality of life. For example, one recent study showed that CBD may help dogs feel less stressed. Another study demonstrated that cannabidiol may help reduce anxiety in dogs during car travel.
CBD may also help:
- Support joint comfort
- Promote mobility
- Encourage relaxation for hyper dogs
- Improve sleep
If the aging process is affecting your dog's mental health, CBD may also help promote a calmer demeanor in some dogs. However, more research is needed to better understand its effects on age-related behavioral changes, including aggression.
While CBD is not a replacement for a healthy routine or regular veterinary care, it may help support your dog's overall comfort and emotional well-being, potentially helping some dogs feel calmer and more at ease.
Which Senior Dogs May Benefit?
Some dogs may stay active well into their senior years, while others begin slowing down much earlier. Senior dogs that may benefit from CBD include those who:
- Move slower than they used to
- Act stiff after walks
- Have trouble getting up after lying down
- Seem restless at night
CBD won't stop the aging process or cure underlying health conditions. However, it may help encourage a more active lifestyle.
Choosing a High-Quality CBD Product
When humans use CBD, they can describe how it affects them. Dogs don't have that privilege. That's why it's up to you to choose a product carefully and monitor your dog for any changes after introducing CBD. The golden rule is to choose a high-quality product.
Here are a few things to look for:
- Third-party testing: Independent lab reports verify how much CBD is in the product and screen for unwanted contaminants, such as heavy metals, pesticides, and residual solvents.
- Clearly labeled hemp source: Reputable companies are transparent about where their hemp comes from and how it is grown.
- THC-compliant formulas: Hemp-derived CBD products should contain no more than 0.3% Delta-9 THC on a dry-weight basis, in accordance with federal regulations.
- Simple ingredients: Avoid unnecessary fillers, artificial flavors, colors, or ingredients you don't recognize.
Whenever possible, choose CBD products that are specifically formulated for dogs, as they are designed with canine use in mind. However, if those products aren't available, look for a high-quality CBD product with simple, transparent ingredients and verified third-party testing. The cleaner and more transparent the product, the better.
How Much CBD Should You Give an Older Dog?
The right amount depends on factors such as:
- Weight
- Age
- Overall health
- Sensitivity to CBD
The safest approach is to start with a small amount and increase gradually (if needed). This gives you time to see how your dog responds while reducing the chance of unwanted side effects.
When calculating dosage for your dog, remember that some senior pets respond well to very small amounts because their metabolism slows with age.
Possible Side Effects
When you give CBD to your pet, watch its reaction closely. The unwanted side effects can include:
- Sleepiness
- Temporary digestive upset
- Changes in appetite
If you notice these signs, reduce the amount of CBD. If the symptoms continue, stop using the product and contact your veterinarian. CBD may interact with certain drugs, so if your dog is taking meds, consult your vet before implementing cannabidiol into the routine.
Frequently Asked Questions
Can senior dogs take CBD daily?
Many owners include CBD as part of their dog's daily wellness routine. However, before adding CBD to your dog's routine, consult your veterinarian to make sure it's appropriate for your pet's individual needs.
Is CBD safe for old dogs?
Current research suggests that many dogs tolerate CBD well. However, studies are still ongoing. Always choose a high-quality product and consult your veterinarian before getting started.
Can CBD help support mobility?
CBD may help support joint comfort and mobility in some senior dogs. While it is not a treatment for arthritis or other medical conditions, it may help some dogs feel more comfortable during everyday activities.
How long does CBD take to work?
CBD oil may begin working within 30 to 60 minutes, while CBD treats and chews can take longer to produce noticeable effects. Some dogs may also need several days of consistent use before you notice changes.
CBD oil or CBD treats?
Both can be effective. CBD oil makes it easier to adjust the amount given, while treats are often more convenient and appealing for dogs. The best option is the one that fits both your dog's preferences and your ability to use it consistently.
Final Thoughts
Growing older is a natural part of every dog's life. While you can't stop the aging process, you can take steps to help your pet stay comfortable and maintain a good quality of life. Supporting your dog's overall health and well-being may also contribute to a longer, happier life.
CBD is not a substitute for regular veterinary care. However, it has the potential to support comfort and promote mobility as part of a comprehensive wellness plan.
If you decide to try CBD for your pet, always choose a high-quality product and introduce it gradually. Working together with your veterinarian is the best way to develop a safe and effective wellness routine tailored to your dog's individual needs.
