After years of working with pet owners and perfecting our CBD formulas, we've seen firsthand how beneficial CBD can be when used correctly and how important it is to know the right amount to give. Understanding the symptoms of too much CBD in dogs helps prevent unwanted side effects and ensures a safe, positive experience for your pup.
We'll explore what can happen when a dose is too high, the signs that tell you your dog might have had enough, how to handle it if it occurs, and simple ways to find the perfect balance for their wellness routine. It's all about keeping your dog happy, healthy, and feeling their best.
What this article covers:Yes, you can give too much CBD to your dog. While a true overdose is extremely unlikely with hemp-derived CBD, giving more than your dog can comfortably handle can lead to mild but unpleasant side effects. Most often, this happens when the dose is increased too quickly or when a dog's individual sensitivity isn't taken into account.
The good news is that these effects are typically temporary and can be managed with simple care and a little patience.
When a dog is given more CBD than it needs, certain symptoms can appear. Knowing what to look for helps you act quickly and adjust the dose for your dog's comfort.
One of the most common signs of too much CBD is drowsiness. Your dog may suddenly seem tired, uninterested in playtime, or unusually calm. This usually means the dose is too high for their system and needs to be reduced.
CBD can temporarily reduce saliva production, leading to dry mouth. You might notice your dog drinking more water than usual or having a dry nose and gums. Keeping fresh water available helps, but you should also consider lowering the dose.
Vomiting or diarrhea can occur if your dog's stomach doesn't agree with the CBD oil or the carrier oil in the product. Some dogs are simply more sensitive than others. Starting with small doses and increasing gradually helps avoid this.
In some cases, dogs might appear wobbly or light-headed after taking too much CBD. This can be related to a temporary drop in blood pressure. If your dog seems unsteady, help them rest and reduce the next dose.
You may notice your dog eating more or less than usual, or just acting a bit “off.” Appetite changes are another sign that your dog's body is adjusting (or reacting) to too much CBD.

Even the most careful pet parents can accidentally give their dog a little more CBD than intended, and that's okay. You just need to know how to respond calmly and confidently so your pup stays safe and comfortable while the effects wear off.
Don't panic. Most reactions to CBD are mild and temporary. Keep your dog comfortable, offer plenty of fresh water, and stay nearby so you can observe any changes in behavior, appetite, or coordination.
If your dog shows signs of having too much, pause CBD for a day or two. Once they seem back to normal, resume with a smaller amount. It's better to reintroduce slowly than risk another reaction.

If your dog's symptoms seem severe, like vomiting, extreme lethargy, or loss of balance, call your veterinarian. Having the CBD product on hand, along with details about how much was given, will help your vet assess the situation quickly.
Sometimes dogs just need a little extra comfort. Make sure they have a quiet space to rest, keep them hydrated, and encourage light movement when they're ready. If they're refusing food, offer something gentle on the stomach, like plain boiled chicken or rice, once they're feeling better.

After your dog has recovered, take a moment to rethink how you're giving CBD. Double-check the product's strength, your measuring method, and your dog's weight to ensure accuracy. Using a CBD dosage chart or talking to your vet can help you fine-tune the right amount.
To make sure that you're giving your dog its CBD correctly, be sure to read our guide on how to administer CBD oil to dogs.
The right CBD dose varies for every dog, but there are solid guidelines to start with. For small dogs under 20 pounds, begin with around 1 to 2 mg of CBD per dose. Medium dogs between 20 and 50 pounds can usually start with 3 to 5 mg, while larger dogs over 50 pounds may need anywhere from 6 to 10 mg.
Give CBD once or twice a day, depending on your dog's needs and how they respond. If you're using a stronger oil, make sure to check the concentration so you're not giving more than intended. From our experience, gradual adjustments every few days help you find that sweet spot where your dog is relaxed, comfortable, and alert without showing any side effects.
Finding the perfect dog CBD dose can take a bit of trial and observation, but it's worth the effort. Every dog is unique, and with a little patience and consistency, you can discover the amount that delivers the best results for their overall well-being.
Always begin with a conservative dose and watch how your dog responds over a day or two. If there are no side effects and the results are positive, you can gradually increase the amount.

Only use CBD products formulated specifically for dogs. Dog CBD products are made with safe carrier oils and concentrations suitable for canine systems. Quality and transparency matter. Always choose brands that provide third-party testing and clear dosage guidance.
Every dog is different. Larger dogs can usually handle higher amounts, while smaller or older dogs may need less.
If your dog has existing health issues or takes other medications, consult your vet before adding CBD to their routine. While CBD can assist as part of a wider health regimen for certain medical problems, the CBD oil dog seizure dose is usually on the higher side and should be monitored closely with professional guidance.
Understanding how to recognize and respond to the symptoms of too much CBD in dogs is the best way to keep your pup safe and happy. By learning what signs to look out for, knowing how to adjust the dose, and taking simple steps if your dog gets a little too much, you can make CBD a positive part of their wellness routine.
The right balance helps your dog enjoy all the calming and supportive benefits without any unwanted effects. For high-quality pet CBD products you can trust, explore the King Kanine collection today and find the perfect fit for your furry friend.
