A vet's guide to gabapentin for dogs: everything you need to know
Why do veterinarians prescribe gabapentin for dogs, and what should you know about this medication?
Veterinarians use gabapentin in dogs for a number of different purposes. This drug (brand name: Neurontin®) was initially developed to treat partial seizures in humans, but it was later also found to be useful in the treatment of neuropathic (nerve) pain. Although its precise mechanism of action is poorly understood, it has a number of beneficial effects on the canine nervous system, Gabapentin is most commonly used in dogs to treat anxiety and chronic pain, but it can also be useful in the treatment of seizures and muscle tremors.
Gabapentin carries a low risk of serious side effects, combined with an affordable cost that may be even lower if you have the best pet insurance for your dog. These factors make it a practical and helpful medication, when medically indicated.
Gabapentin for dogs: anxiety
Gabapentin is often used for the management of mild situational anxiety in dogs. For example, if your dog is terrified of veterinary visits, your veterinarian may prescribe a dose of gabapentin (given alone or in combination with another medication) to give before vet visits, to reduce anxiety. When used in this way, gabapentin can help “take the edge off” a dog’s situational anxiety.
Gabapentin is not typically used as an everyday medication or to treat severe anxiety. There are other drugs that are far more effective in that context. Gabapentin is only beneficial in some cases of mild situational anxiety.

Gabapentin for dogs: pain
Gabapentin can also be used as a pain medication, specifically in the case of chronic nerve-related pain. Your veterinarian might prescribe gabapentin if your dog has intervertebral disk disease, any other condition leading to compression of the nerves or spinal cord, or even in some cases of arthritis pain.
While controlled studies on the role of gabapentin in pain management are limited, many clients and veterinarians have seen favorable results in their pets. Given the low risk of side effects associated with gabapentin, it’s reasonable to try in dogs with chronic pain that cannot be controlled with other medications.
Gabapentin for dogs: dosage
The dose of gabapentin varies significantly, based on your dog’s weight and the intended goal of the medication. A 10 pound dog may receive as little as 50 mg of gabapentin prior to a veterinary visit, while a 100 pound dog with severe pain may receive as much as 1000 mg of gabapentin every eight hours. Gabapentin is typically given every eight to twelve hours, with peak benefits occurring roughly two hours after dosing.
Your veterinarian will prescribe an appropriate dose of gabapentin for your dog, depending on your dog’s weight and treatment goals. Veterinarians typically start with a lower dose, and then gradually increase the dose as needed. This helps maximize treatment benefits, while minimizing the risk of side effects. Contact your veterinarian if you feel that your dog’s dose is too high or too low. It may take several dosage adjustments to find the optimal dose of gabapentin for your dog.
Gabapentin may be given with or without food.

Gabapentin for dogs: side effects
The most common side effects of gabapentin are sedation and incoordination. These effects are usually short-lived. Your dog may appear slightly sedated for a few hours after their first dose, and then tolerate the drug well after that point. In some cases, these effects may last a few days, resolving as your dog gradually becomes acclimated to the medication.
If your dog experiences continued sedation or incoordination after several days of treatment, or if these effects are severe or otherwise concerning, contact your veterinarian. Your veterinarian can determine whether your dog needs a reduction in dosage or a change to a different medication.
The sedating effects of gabapentin may be more obvious if your dog takes other sedating drugs, such as antihistamines, mirtazapine, or narcotic pain medications. Talk to your veterinarian if you are concerned about potential drug interactions.
Gabapentin should be avoided during pregnancy.
How much does Gabapentin cost?
Many veterinary practices stock gabapentin in their practice pharmacy. Alternatively, you may receive a written prescription that you can have filled at a human or veterinary retail pharmacy. Be aware that gabapentin is considered a controlled drug in some states, which may limit your ability to order it through online pharmacies.
Because gabapentin is typically given in its generic form, the cost is quite low. Depending on your dog’s dose and where you purchase the medication, you can expect to pay anywhere from $10 to $50 per month for continuous daily gabapentin dosing. This cost may be even lower if you have pet insurance or a prescription plan that you can use for your pet. If your dog is going to be on gabapentin long term, you may want to familiarize yourself with Pet insurance vs prescription plans. Also, while most pet insurance plans will not provide coverage for pre-existing conditions, if your dog has a medical condition that requires gabapentin treatment, look into whether the Best pet insurance for pre-existing conditions may help you cope with the financial aspects of your pet’s treatment.
Gabapentin in dogs: a summary
Veterinarians use gabapentin in dogs to treat a number of conditions, including situational anxiety, chronic pain, and (less commonly) seizures or muscle tremors. This medication is very affordable and low in side effects, making it a low-risk option for many dogs. There is significant variation in gabapentin dosing requirements, depending on your dog’s size and medical condition, so you will need to work closely with your veterinarian to find the optimal gabapentin dose for your dog.
