Understanding the potential side effects of any medication we give to our pets is a crucial aspect of responsible pet ownership. Today we’re focusing on gabapentin, a common medication prescribed to dogs for various reasons. While it’s generally safe and effective, it’s essential to be aware of its potential side effects.

What is Gabapentin?

Gabapentin is a medication initially developed for treating seizures in humans. However, it’s increasingly used in veterinary medicine due to its efficacy in managing pain, especially neuropathic pain, and its ability to control seizures in dogs.

While gabapentin is generally well-tolerated by dogs, like any medication, it’s not without potential side effects.

Common Side Effects of Gabapentin in Dogs


One of the most common side effects of gabapentin in dogs is sedation. This is particularly prevalent in the initial stages of treatment or when the dose is increased. Dogs on this medication may often appear lethargic or drowsy, seemingly fatigued and less energetic than usual.

Loss of Coordination

As a consequence of the induced sedation, gabapentin may also affect a dog’s motor skills. This often leads to a noticeable loss of coordination, causing the dog to stumble or appear unsteady. It’s an important side effect to be aware of.

Gastrointestinal Upset

The last common side effect of gabapentin is that it can sometimes trigger gastrointestinal upset in dogs. This manifests as symptoms like vomiting or diarrhea, thus it’s crucial to closely monitor your dog’s eating habits and stool consistency while they are on this medication. Any drastic changes should be reported to your veterinarian to ensure the well-being of your pet.

Less Common, But Serious Side Effects

While less common, some dogs might experience more severe side effects. These could include:

Allergic Reactions

In some instances, dogs may exhibit allergic reactions to gabapentin. These signs can encompass a spectrum of symptoms, including difficulty breathing, swelling of the lips, tongue, or face, and the appearance of hives. Should you notice any of these alarming symptoms in your dog, it’s imperative to seek immediate veterinary attention to ensure their safety.

Changes in Behavior

Beyond physical reactions, gabapentin may also provoke changes in a dog’s behavior. This can manifest as increased aggression or anxiety in your furry friend. While these instances are relatively rare, they are nonetheless important to be mindful of. It’s crucial to keenly observe any sudden behavioral changes in your dog while they’re on this medication, as it could indicate an adverse reaction that needs addressing by a professional.

What to Do If You Notice Side Effects

If you notice any of these side effects in your dog, it’s vital to contact your veterinarian immediately. They may adjust the dosage or suggest an alternative treatment. Never attempt to adjust the dosage or discontinue the medication without consulting with your vet.

CBD as an Alternative to Gabapentin

In recent years, cannabidiol (CBD) has gained popularity as a natural alternative for managing various conditions in dogs, including pain and seizures, which are commonly treated with gabapentin.

CBD is derived from the hemp plant but doesn’t contain significant amounts of THC, the compound responsible for the ‘high’ in marijuana. This makes it a safe option for use in dogs.

Research on CBD use in dogs is still in the early stages, but preliminary studies and anecdotal evidence suggest that it may be effective in managing pain and reducing seizure frequency. Furthermore, the side effects of CBD appear to be mild compared to many traditional medications.

It’s important to note that while CBD can be a beneficial addition to your dog’s treatment plan, it should not replace any current medications unless advised by your vet.

Precautions While Using Gabapentin

While we’ve discussed the side effects of gabapentin, it’s also important to consider some precautions when using this medication.

Renal Issues

Gabapentin is eliminated from the body through the kidneys, so it should be used with caution in dogs with kidney disease. Your veterinarian may adjust the dosage or monitor your dog’s kidney function more closely if they have any existing renal issues.

Drug Interactions

Another important aspect to be aware of is that gabapentin can have interactions with other medications your dog might be taking, such as antacids, opioids, and certain anxiety medications. Hence, it’s of utmost importance to always keep your vet fully informed about any other medications your dog is on, to circumvent possible harmful drug interactions.

Pregnant or Nursing Dogs

For pregnant or nursing dogs, the impact of gabapentin is not entirely understood or defined. If your dog falls into either of these categories, it’s essential to have a comprehensive discussion about potential risks with your vet before commencing treatment with gabapentin.

The Role of Regular Vet Check-ups

When your dog is on long-term medications like gabapentin, the significance of routine vet visits cannot be overstated. Regular check-ups present an opportunity for your vet to monitor the medication’s effectiveness and adjust the dosage if necessary. Early detection of potential side effects or health issues can also make a huge difference, improving the prognosis and potentially saving you substantial treatment costs in the long term.

Wrapping Up

Gabapentin can serve as an effective tool in managing pain and seizures in dogs. However, like all medications, it comes with its set of potential side effects. It’s of critical importance to be aware of these side effects and maintain open communication with your vet regarding any concerns or changes observed in your dog.

While CBD may be considered as a natural alternative or supplement to traditional medications like gabapentin, it’s recommended to approach this option with thorough research and under the guidance of a vet.

Remember, at the forefront of all considerations is your dog’s health. By comprehending the side effects of gabapentin, you are proactively contributing to the best possible care for your canine friend. Always heed your vet’s advice and never hesitate to consult them with any questions or concerns. It’s this collaborative relationship between you and your vet that will secure your dog’s optimal health and well-being.
