CBD oil has become a popular natural remedy for dogs dealing with anxiety, pain, inflammation, and even seizures. While many pet owners report positive results, it’s important to understand that CBD isn’t without potential side effects. Just like humans, every dog can react differently to cannabinoids. Before introducing CBD into your pet’s wellness routine, it’s essential to be informed about the possible adverse effects and how to use it responsibly.
10 Possible Side Effects of CBD For Dogs
1. Thirstiness
One of the most common side effects of CBD in dogs is increased thirst, even in cooler indoor environments. This side effect is similar to what some humans experience with CBD. However, it is easily manageable by ensuring your dog has constant access to fresh water. Without enough hydration, your dog may start drooling as a sign of dehydration, so keeping water available is essential.
2. Drowsiness or Sedation
CBD can have calming effects on dogs, which might lead to increased relaxation or sleepiness. This is especially common at higher doses and may be beneficial for dogs with anxiety but could interfere with their energy levels if excessive.
3. Dry Mouth
CBD may reduce saliva production in dogs, leading to increased thirst. You might notice your dog drinking more water than usual after consuming CBD.
4. Low Blood Pressure
CBD has the potential to cause a temporary drop in blood pressure, which may make your dog feel slightly dizzy or unsteady. This effect is usually mild and short-lived.
5. Diarrhea
Some dogs might experience loose stools or diarrhea, particularly when they are new to CBD or if the product contains certain carrier oils that upset their stomach.
6. Changes in Appetite
CBD can influence a dog’s appetite, either increasing or decreasing it. These changes vary from dog to dog and may depend on the dosage.
7. Lethargy
CBD’s calming properties might result in a lack of energy or sluggishness, especially if the dose is too high for the dog’s weight or tolerance level.
8. Allergic Reactions
Although rare, some dogs might exhibit allergic reactions to CBD or its ingredients. Signs may include itching, hives, swelling, or other symptoms of irritation.
9. Vomiting
Dogs with sensitive stomachs might vomit after consuming CBD, particularly if they have difficulty tolerating the oil or other additives in the product.
10. Interaction with Medications
CBD can interact with other medications, especially those metabolized by the liver. This could alter the effectiveness of certain treatments or increase the risk of side effects. Always consult your veterinarian if your dog is on medication.
What Is CBD?
CBD, or cannabidiol, is a naturally occurring compound found in the cannabis plant, specifically in hemp. Unlike THC (tetrahydrocannabinol), another well-known compound in cannabis, CBD is non-psychoactive, meaning it doesn’t cause a “high.” Instead, it interacts with the body’s endocannabinoid system (ECS), which plays a key role in maintaining balance and regulating functions such as mood, sleep, appetite, and immune response.
How CBD Works in Dogs
The endocannabinoid system (ECS) is a crucial part of your dog’s biology, responsible for regulating a variety of bodily functions such as mood, sleep, pain, and appetite. The ECS is made up of receptors located throughout the body, including in the brain, organs, and immune system. These receptors interact with naturally occurring compounds in the body called endocannabinoids, which help maintain balance, or homeostasis.
CBD, when introduced to your dog’s system, interacts with the ECS by binding to these receptors. Although it doesn’t directly activate the receptors like endocannabinoids, CBD helps to enhance their natural effects, leading to potential benefits such as reduced anxiety, pain relief, and improved joint health. By supporting the ECS, CBD can help your dog manage discomfort, stress, and other health issues, promoting overall wellness.
The Endocannabinoid System in Dogs
CBD (cannabidiol) interacts with the ECS differently than the body’s natural endocannabinoids:
- Indirect Activation: Unlike THC, which binds directly to CB1 and CB2 receptors, CBD doesn’t attach directly. Instead, it influences the receptors indirectly, enhancing the ECS’s ability to maintain balance.
- Enzyme Inhibition: CBD can inhibit FAAH, which slows the breakdown of anandamide, allowing it to stay active longer and promote its calming and pain-relieving effects.
- Receptor Modulation: CBD also interacts with other receptors outside the ECS, such as serotonin receptors, contributing to its anti-anxiety and anti-inflammatory effects.
Signs and Symptoms of Too Much CBD in Dogs
Mild Symptoms
- Lethargy or drowsiness
- Uncoordinated movement (ataxia)
- Excessive drooling
- Vomiting or diarrhea
Moderate to Severe Symptoms
- Disorientation or confusion
- Low blood pressure
- Increased or decreased heart rate
- Shaking or tremors
- Vocalization (whining or howling)
- Dilated pupils
Can a Dog Overdose on CBD?
In the conventional sense of the word “overdose,” CBD does not pose a fatal threat when consumed in large amounts. However, this doesn’t mean there are no consequences. A dog can experience an overdose-like reaction, where their body becomes overwhelmed by the compound and begins to exhibit a range of symptoms, some mild, others more concerning.
The risk is greater when the dog ingests an entire bag of CBD treats or consumes a high dose of full-spectrum oil (which may contain small traces of THC). The side effects of a CBD overdose typically involve gastrointestinal discomfort, fatigue, and temporary motor impairment, but more severe symptoms can occur if the product wasn’t meant for pets or contains additional cannabinoids or toxic ingredients.
How to Use CBD Safely for Dogs
Start with a Low Dose and Monitor Your Dog: Begin with a low dose of CBD, especially if your dog has never used it before. Monitor your dog’s behavior and any changes in their condition. This helps you assess how they respond to the product and ensures they don’t experience any adverse effects.
Adjust Dosage Based on Your Dog’s Response: Every dog is different, and their CBD needs may vary based on factors like size, age, and health condition. If your dog responds well to the initial dose, you can gradually increase it to find the optimal amount. However, always stay within the recommended dosage range to avoid overuse.
Importance of Reading Product Labels and Vet Guidance: Always read the product labels to ensure you’re using the correct CBD product for your dog’s size and needs. Consulting with your veterinarian is also crucial, especially if your dog has existing health conditions. Your vet can help you create a tailored CBD dosage guide for dogs and provide advice on using CBD for dogs safely.
Bottom Line
CBD can offer promising benefits for dogs, but it’s not without potential side effects. Always start with a low dose, monitor your pet closely, and consult your veterinarian, especially if your dog is on other medications. With the right approach, CBD may be a safe and effective addition to your dog’s wellness routine.
