What is Gabapentin Used for in Dogs?

Gabapentin is a very common and useful drug to relieve the pain and anxiety of your canine companion.

Initially, gabapentin was designed for humans, and after evolving, it is now used for animals like cats and dogs. It is used for animals more than it is used for humans.

No exact mechanism has been discovered, but it works by readjusting the nervous system, which signals the brain.

Gabapentin is either given in a liquid form or a tablet form. As it takes time to fully effect, veterinarians recommend this drug for chronic pain rather than temporary pain.

Gabapentin is used to treat different health issues in dogs, such as:

1. Anxiety Control

Anxiety Control

Gabapentin is often used to ease anxiety disorders in dogs. There is a specific medication named trazodone which is an anti-anxiety medication.

Many people are curious and often ask if it is safe to combine trazodone with gabapentin, so the answer is yes, you can combine. Many pharmaceuticals even provide a combined solution to treat anxiety.

2. Preventing Seizures

When no other medication is effective in controlling seizures, Gabapentin is advised by vets as it contains anticonvulsant properties, which are very useful in preventing seizures and nerve control.

3. Pain Management

Pain Management

A dog in chronic pain is prescribed gabapentin, which is useful for treating chronic pain. It is often given with other pain-relieving drugs, such as carprofen.

It is given for chronic pain relief or conditions like osteoarthritis and joint pains, as chronic pain changes the brain’s pain pathways. It is also given for post-surgery pain.

Other conditions where Gabapentin is used are:

  • Chronic pain.
  • Nerve pain.
  • Chronic arthritis pain.
  • Back and Neck pain.
  • Intervertebral disc disease.
  • Muscle Spasms.
  • Excessive Thirst.
  • Nystagmus.

What are Potential Gabapentin Side Effects in Dogs?

Side effects of Gabapentin are rare, but as with all drugs, there may be some side effects that may occur in some animals.

Consult your veterinarian immediately if your pet shows any of the below-mentioned signs of side effects.

1. Lethargic or Sleepy

Lethargic or sleepy

Dogs are likely to be sleepy or lethargic if they are sensitive to this drug. It may also depend on the dosage, and this is the primary potential side effect of gabapentin.

2. Ataxia or Loss of Balance And Coordination

This is another side effect of gabapentin, as your dog may seem drunk or too tired to work properly.

A swaying, staggering gait often characterizes it. Contact your veterinarian immediately if your dog displays this sign. The vet may modify the dosage or change the drug altogether if it gets complicated.

3. Diarrhea


Though often uncommon, some dogs may display diarrhea as a side effect of gabapentin. This is a rare side effect of gabapentin medication and varies from dog to dog.

All these signs are potential side effects of gabapentin, and their seriousness and severity will depend on the drug’s dosage, the dog’s condition, and the dog’s age.

What Should I Do if My Dog had a Double Dose of Gabapentin?

This is often a common and big question many new pet parents ask. What will happen, and what should I do, as my dog had a double dose of gabapentin?

The first thing a dog owner should know is to not panic in these situations as it will only worsen the situation, as you won’t be able to see the current symptoms your dog is displaying.

Here’s what you should do. Start looking for any above-mentioned symptoms of side effects your dog might display after a double dose of gabapentin.

If your dog is wobbly or showing signs of imbalance, keep them away from heights and other areas or objects from which your dog may fall or get hurt.

Next, refrain from giving home remedies or supplements to make him vomit or get better. It may unknowingly worsen the situation.

Call your veterinarian, and ask for instructions. Your vet will guide you on how to proceed further.

Precautions to Take When Offering Gabapentin to Your Dog

Prevention is better than cure, and taking precautions while offering gabapentin will help your dog get healthy quicker with fewer complications.

A few points should be considered while offering gabapentin to your dog.

1. Give The Prescribed Dosage

Give The Prescribed Dosage

Always ensure your dog gets the accurate dosage of gabapentin as your veterinarian prescribes.

2. Do Not Compensate For The Dosage

If your dog misses a dose, do not offer a double dose in the next schedule to compensate for the missed one.

To note here is the timing; if you have missed the dose for your dog and the next schedule is only minutes away, do not offer a dose; just let it pass.

If the next fixed schedule for the dosage is hours away, you can give it but never compensate or double the dosage.

3. Do Not Give a Dose After Overdosage

Do Not Give a Dose After Overdosage

It is important to understand the effects of over-dosing gabapentin in your dog.

If your dog has overdosed, talk to your vet about how to proceed with the medication schedules, and your vet will prescribe a new one.

Do not offer a dosage after an overdose; always let it get metabolized and completely out of your dog’s system.

4. Inform Your Vet of Other Medications

When you take your dog to see the veterinarian who prescribes gabapentin dosage, inform the vet about any other medications your dog has been prescribed before the visit.

Informing your veterinarian about other medications will lower the chances of side effects and interactions caused by consuming a combination of drugs like hydrocodone and morphine.

Also, ask your vet to prescribe a lower dosage and, more often, a tablet than the liquid ones in the market.

It is better for the dogs if they consume less gabapentin. And avoid liquid solutions of gabapentin, as they are often sweetened and harmful to dogs.

5. Avoid Sudden Stoppage of Gabapentin

Avoid Sudden Stoppage of Gabapentin

Avoid stopping the medication as it may cause wind-up pain and seizures in dogs.

It is better to talk to a veterinarian and slowly decrease the gabapentin offering. Abruptly discontinuing gabapentin can cause side effects.

If you see an allergic reaction to gabapentin, tell your veterinarian, and he/she may recommend other drugs.

6. Keep Drugs Away From Reach

Keep your gabapentin and other drugs or harmful chemicals away from your dog’s reach.

Your pet can often jump up to a good height, and if they come across any chemicals or drugs, it can lead to many fatal health issues like overdose or skin burns and other harmful chemical reactions.


Q. How long does it take for Gabapentin to work on dogs?

It usually starts working in an hour or two, and you can see its effects on your dog, and the medicinal effect will last up to four hours; this is for most dogs. It also varies on the breed and the dosage of the medication.

Q. Can gabapentin cause diarrhea or constipation in dogs?

Dogs can get these health issues after gabapentin dosage, but it is very uncommon. Vomiting, diarrhea, and constipation are some of the very rare side effects which are only seen when dogs are administered at high doses of gabapentin.

Q. How to know if gabapentin is treating my dog’s pain?

It is very easy to know if gabapentin suits your dog and works. Observe your dog; if it is jumping, climbing, or running as it used to before getting ill, it means the drug is working well. They will climb up the stairs and furniture and start playing. If not, let your vet know after a few doses, and then they’ll decide further.
