Full-spectrum CBD oil as an effective natural treatment plan for our pets has gained much traction and popularity in the last few years. Although the research that has been conducted is minimal and largely anecdotal, pooch parents have found this alternative treatment to be incredibly helpful for their pups, whether it be for mild or more severe conditions. It is essential to understand and be well informed with all the relevant information for the safety of our pets. Your vet will be able to offer support and give up-to-date information on the research that has been conducted.

We know that CDB oil does seem to have an array of benefits in treating various conditions, such as anti-inflammatory properties, reducing anxiety, providing effective pain management, reducing seizures, and decreasing nausea and digestive issues. However, are there any side effects, and what can you do about them?

It’s also absolutely vital to know the potential cons of giving your dogs CBD oil. Side effects are rare, but because not all CBD products have the same concentration of CBD, giving the correct dose can be tricky. There is no TCH in CBD oil, so there is no risk of your pup feeling any of the psychoactive effects, but you should keep an eye out for the following side effects:

  • Dry mouth If your dog is struggling with a dry mouth, it may result in bad breath, poor dental health, and in some instances, it can be uncomfortable for them to swallow. Once you’ve given them their CBD dose, have a bowl of water close by to help with the cottonmouth and keep them hydrated.
  • Lethargy or laziness This usually occurs if the dose administered is too large. Rather give smaller doses to your dog if you notice lethargy in an otherwise active dog after giving them CBD oil. A range of 1-5mg per 10 pounds of body weight is generally recommended.
  • Dizziness If your dog is falling over or can’t stand up properly, it could mean that the CBD you have used is poor quality or contains trace amounts of THC. This creates a greater risk for your dog feeling dizzy or out of sorts. High-quality full-spectrum products like those found on our online store
    are guaranteed to contain no traces of THC or cause dizziness.
  • Upset stomach or vomiting You have introduced something new to their tummies, so it might upset their stomach before they get completely used to it. Some dogs may have issues with diarrhea due to CBD intake (although many things can cause diarrhea in dogs). It could be due to a higher dose, or they might just not like the taste of the oil. Treats may be the best way to go as they’ll have tastier ingredients added to make them more palatable to your dog.
  • Low blood pressure CBD could cause a drop in blood pressure temporarily if it is given high doses. Again, it’s important to stop or lower the dose if this occurs.
  • Itching This is not a common side effect, but itching can occur after a dose of CBD. If your dog is scratching or itching a lot more than usual, then you might need to lower the dose or stop administering CBD altogether.
  • Tremors There have been many encouraging testimonials from dog owners who have shared how CBD has helped their furry friends with seizures and epilepsy. However, if your dog struggles with Parkinson’s Disease, CBD may potentially increase their tremors, in which case you should consult your vet before administering any CBD products.


If you’ve noticed that your dog is experiencing any of the above adverse side effects of CBD oil, contact your vet immediately. More often than not, this is due to dosages that are too high. Your trusted vet can advise and recommend what dosage will be ideal for your pet or if they should be taking CBD oil at all.
