FAQs: Gabapentin and Dogs

1. What is Gabapentin?

Gabapentin, originally developed for treating epilepsy in humans, is now widely prescribed in veterinary medicine. Its primary use is for managing neuropathic pain, anxiety, and seizures in pets, especially dogs.

2. The Gabapentin-Seizure Conundrum

There’s a certain irony to the question: Can a drug used to treat seizures also cause them? Let’s dissect the available information:

  • Clinical Trials and Studies: As of 2021, few clinical studies directly link gabapentin to causing seizures in dogs. Many vets have found the drug beneficial in reducing seizure frequency in dogs with epilepsy.
  • Anecdotal Evidence: Some pet owners on platforms like Reddit have expressed concerns about potential side effects, including increased aggression or sedation in their pets. However, such reports are varied and often unverified.

3. Understanding the Side Effects

The most common side effects of gabapentin in dogs include:

  • Sedation: A common reaction, especially when the dog starts the medication.
  • Ataxia: This refers to a lack of voluntary coordination of muscle movements, making dogs appear wobbly or ‘drunk’.

Rarely, dogs might show signs of:

  • Aggression or restlessness: As observed in some humans, gabapentin might make dogs more irritable.
  • Gastrointestinal problems: Some dogs might experience vomiting or diarrhea.

4. Dosage Matters

An overdose can cause distress in dogs. Common signs include severe sedation, loss of coordination, and even seizures. Always adhere to the prescribed dose and consult with your vet if you notice any abnormalities in your pet’s behavior or health.

5. Withdrawal Concerns

Abrupt discontinuation of gabapentin can lead to potential withdrawal symptoms, including seizures. Hence, if there’s a need to stop the medication, it should be done gradually, under veterinary guidance.

6. A Word on Combination Therapies

Dogs on multiple medications, including gabapentin, require close monitoring. The interaction between drugs can sometimes produce unforeseen side effects.

7. Individual Responses

Remember, each dog is unique. What works for one might not work for another. It’s essential to monitor your dog closely when introducing any new medication and maintain open communication with your veterinarian.


Gabapentin is a valuable drug in the canine medical toolkit, especially for managing pain and seizures. However, like all medications, it should be administered responsibly. If you’re considering gabapentin for your pet, or if you’ve noticed any unusual side effects, always consult with your veterinarian to ensure your furry friend’s health and safety.
